Leaded Atmosphere May Have Delayed Global Warming
The lead in gasoline used until the 1980s may have been responsible for keeping the earth cooler than it would have been otherwise. Researchers at Pacific Northwest National Laboratory in Richland, WA, say that lead "supercharges" ice-nucleating dust particles in the atmosphere. This may have delayed global warming during the middle of the twentieth century and offset it until about 1980, when global temperatures began rising steeply.

AIA Announces Awards for Green Projects
The Portola Valley Town Center and other Peninsula buildings were among the awardees of the recent American Institute of Architects Committee on the Environment "Top Ten Green Projects for 2009." Recipients included The Chartwell School, overlooking Monterey Bay, which uses natural ventilation, daylighting, radiant heating, and photovoltaics; and, the affordable housing complex Gish Family Apartments in San Jose, which features high-density development, passive heating and cooling strategies, and a photovoltaic system. The Portola Valley Town Center is a group of civic buildings that boast a small construction footprint, restoration of site environment, and passive design features.

Projects Show Affordable Homes Can Be Green
Builders in Harrisonburg, VA, are using EarthCraft-certified homes to show that a small initial cost can yield a lifetime of green savings, even in pricier markets. The secret "is getting everybody to do the little things right," according to Aaron Yoder, owner of AM Yoder & Company, who built homes there. That includes good insulation and properly-sealed ductwork. Central Valley Habitat for Humanity has also been building in the area. Their EarthCraft homes cut utility bills. "I was shocked," said one of their residents, who saw her utility bill drop by more than half after moving in. Energy efficient homes in western Massachusetts are also affordable. Homes in Wisdom Way Solar Village have double-wall construction, dense-pack cellulose insulation, rooftop photovoltaics and solar-thermal arrays. While these homes cost about $38,000 above code (mostly for solar), they generate about 80% of their needed power and require heating units about half the size they otherwise would.

Thin Film Solar Tiles Blend In: Solé Power Tile from SRS Energy is practically indistinguishable from plain tile at a distance. The company claims their tiles perform as well as others on the market and are easy to install.

Plastic Cups Boost Biodiesel Performance: Polystyrene, the common material in plastic cups and other foam containers, can be used as an additive to biodiesel fuel. A study by mechanical engineers at Iowa State University shows that the plastic can be dissolved in biodiesel and then used to run a diesel engine. Concentrations up to about 5% by weight increase performance. In biodiesel, the plastic simply disolved, but doesn't break down as readily in petroleum-based diesel.

Heart of Green Awards Honor Green Progress
The Heart of Green Awards honor individuals and organizations for their work helping green go mainstream. Winners included Alicia Silverstone, Deidre Imus, and Summer Rayne Oakes. Awards included local winners, such as Greg Perry, who brought environmentalism to Beachwood High School in Ohio by developing the Ultimate Green Classroom.

Affordable Housing Developers Congregate
Members of the Council for Energy Friendly Affordable Housing (part of NHRA) will meet next week in Los Angeles for a Green Housing Symposium. About 6% of homes are federally assisted, and developers are looking for ways to leverage money from the recent stimulus package, which should result in the development of green affordable homes. The synmposium will be followed by the National Housing & Rehabilitation Association's 2009 Spring Developers Forum.

Carbon Nanotube Lamp Begins to Glow
A 1.4 micrometre nanotube has become the smallest incandescent lamp in an experiment to study quantum effects. The filament will be used to test Planck's black-body-radiation law (which predicts how light will be emitted by matter under the assumption it is made up of discrete packets of energy).

UK Moves to Collecting Food Waste: Homes in South Oxfordshire will get new recycling bins that include a small bin for food waste with a lockable lid and a smaller caddy to keep in the kitchen. Almost any kind of food will be accepted and will then be diverted to be composted.

Lights Out in Harmony: The town of Harmony, FL, is the recipient of the Dark Sky Development of Distinction Award of the International Dark-Sky Association. The award honors communities that actively promote a more natural night sky. The community tries to incorporate and protect nature using elements of the urban design, and is among the first master planned communities to consider the night sky in this equation. Naturally dark night skies are disappearing as urbanization spreads around the world, and the IDA seeks to preserve some of this historical environment.

Original Green Roof Builder Enjoying Big Sur: Architect Mickey Muennig moved to Big Sur, CA, in the early 1970s, while developing eco-minded architecture, including green roof construction. His new home blends into the countryside, and required both environmental and earthquake reviews before it could be built in an area with some of the most stringent building requirements. An exquisite blend of native plants (coastal grasses, chaparral, bush lupine and ceanothus) set off spectacular views.

Editorializing

Consistency Is All I Ask: Noted green building consultant Jerry Yudelson says that we need support for green building that does not falter. When government subsidies and guidance went away in 1985, he said, "the industry collapsed overnight." To avoid a repeat, we need building codes that accurately reflect realities of global warming, governmental incentives that will not go away after a few years, and a lasting infrastructure connecting owners, managers, and agencies over green practices.

Scientists Establish a Carbon Budget for Humanity
To avoid serious environmental damage, scientists say that humanity cannot afford to add more than one trillion tons of carbon to the atmosphere. This sets a limit of about one-quarter of the remaining known fossil fuel reserves available to use. More than that risks pushing average temperature up by more than two degrees Celsius over pre-industrial levels.

Robert Redford Resists New Green Development
Despite a history of supporting environmental causes, Redford is against a proposed development of 275 green housing units near his home in the Napa Valley village of Angwin, CA. Some there say they are preserving the "beautiful agricultural and rural heritage" and complain that the development will increase traffic. However, the houses would be built on property now owned by a local college, and likely some of the homes would be sold to people that work their.

California Cities Look at Public Funding of Solar Panels
Cities are looking at how they can use California law (known as AB 811) to help their citizens finance solar panels. The law allows borrowers to pay back investments in solar panels through property tax payments over a 20 year period.

NY Naval Yard Captures Green Firms: The remade Naval Yard in New York has been repurposed as an incubator, a facility specializing in supporting startup companies. One of them, IceStone, took advantage of the benign environment to overcome early difficulties manufacturing their green product, as shown in this video.

Twitter Quitters: While Twitter is going through an expansion as celebrities join up, its retention rate is less than stellar. Twitter tends to keep only about 40% of new users after they've tried it for a month. This compares with 70% or more for Facebook and MySpace.

Palo Alto Bans Foam Containers: The Palo Alto, CA, city council has banned expanded-polystyrene containers from local food establishments. The new ban will not immediately take effect to allow establishments to work off their existing stocks. Foam containers break down very slowly, and discarded containers can end up in streams and the bay, where they pose a risk to wildlife.

Understanding Complexities of Solar Panels Necessary to Proper Purchase: Solar panels have become complex machines for generating electricity. Minimum warranted power, STC/PTC ratings, efficiency ratings, and other independent information is necessary to understanding what you may be purchasing.

CO2 Soaring in Arctic
A study of CO2 levels at Zeppelin research station on Svalbard, Norway, suggests levels have reached a record high. Pre-industrial-revolution levels were around 280 ppm, but the station measured levels at 397 ppm. The new data suggests levels are changing 2-3 ppm per year, a rapid rate. Scientists believe that levels above 450 ppm would result in temperature increases of two degrees Celsius on preindustrial global average temperature.

NAFTA Challenge for New California Low-Carbon Fuel Rules
California's recently adopted rules requiring energy producers to take 10% out of the carbon intensity of their products by 2020 may be in for challenges from producers that claim NAFTA and WTO rules would prohibit the requirements. Canadian officials think the rules discriminate against dirty sources of fuels like tar pits. The rules force refiners to consider the carbon footprint of the fuels they produce. Since oil refined from oil sands requires large expenditures of natural gas, this puts a strain on synthetic fuel producers. But, nothing in the regulations appears to be different based on where the fuel is produced.

Electric Car Resurging
The all-electric car is about to make a comeback, based on lighter, more sophisticated and efficient batteries. Billed as second cars with a range of about a hundred miles, they will be used for running errands, taking kids to school, and similar tasks. Nissan expects to have a model out by the end of next year. This will be a full car that seats five and can charge to 80% capacity in less than a half-hour. One lesson automakers learned from the last cycle was to field test their cars. So, they have them out in government fleets before putting them on the market for consumers.

Green Necessity Forces Real Estate Industry to Learn: The sudden change of sustainability from a fringe interest to a mainstream trend has forced many in the real estate industry to go looking for information on green homes and construction. This is creating a demand for green building education for a wide segment of the industry. A number of institutions are developing to fill the gap. But, the best place to learn may be on the job, as property teams put their employees through LEED-EB certification and similar training.

20 MW Solar Thermal Plant Comes Online in Spain: A new solar farm that can generate enough power for 10,000 households is going online near Seville, Spain. The Abengoa Solar facility boasts a 531-foot tower, the world's largest, and captures energy from 1,255 mirrored heliostats.

New Material Maximizes Gas Absorption: A new material of zinc oxide made with nanocluster crystals maximizes the surface area of the substance, allowing it to capture gases (such as hydrogen) in tiny pockets. An once of the material has the same surface area as a football field and may help researchers overcome storage problems that currently make hydrogen power storage impractical for most applications. The substance makes use of tiny variations in the electrical charge of hydrogen molecules that cause them to stick briefly. Large surface areas magnify this effect.

Home Ventilation Required in Tighter Houses: According to the EPA, houses can have air pollution levels two to five times that of outside air (at the same location). Many homes are gaining energy-efficiency through tightening up the envelope to stop air leaks. But this can lead to increased indoor air quality problems unless the home is properly ventilated. Controlling air flow is the key to saving heating and cooling costs, but requires positive measures, such as ventilation fans and heat exchange ventilators. Fortunately, newer equipment is Energy-Star-rated and can be whisper quiet.

Economics of Net-Zero Homes Shifting: After last year's price increases in energy costs, architects and homebuilders have re-evaluated the economics of energy efficiency. While ecologically-friendly housing for many years has been sold on its environmental merit, future energy pricing is being factored into current building equations. "Actually saving money has been considered the last hurdle for the green movement, which got sideswiped by the economic crisis." But, the pace of technological change is making buying decisions tough, not unlike the situation in the home computer market during the 1990s.

Producing Biofuel Can Be Dangerous to Your House
Producing your own biodiesel in your garage can burn your house down. Fire officials are warning of the dangers and considering new restrictions. "Ferocious" fires and explosions blamed on backyard refining operations have been reported in many states, as the ingredients are highly flamable. Even those who advocate the practice warn of the dangers, asking people to take precautions such as storing chemicals in metal cabinets and keeping fire extinguishers on hand.

Obama Calls for More Science Spending
President Obama wants more than three percent of the nation's GDP to go to research and development. In remarks at the annual meeting of the National Academy of Sciences in Washington, DC, the President also called for a renewed commitment to math and science education.

Is the Cost of Environmental Repair Being Understated?
Robert Samuelson of Newsweek report that claims being made about the relatively low cost of addressing global warming are understating the actual costs. He cites a claim from the Environmental Defense Fund that it would only cost ten cents a day per person to solve climate change, which would be true only under the most optimistic economic conditions. While this may be true, motivating the public to take action is not an easy task, and possibly overstating the costs risks demotivating the exact people that need to make changes.

Amish Survive on Hard Work: You might think that the recession has affected everyone in the country, but one large sector of people are buffered from the downturn: the Amish. But, even their isolated economy is feeling the effects from their customers, who are not buying as much. Still, a lot of customers come from upscale households, which are still spending. "If they want to spend, they want quality," says Raymond Bontrager of Maple Lane Woodshop in Wisconsin. Since the Old Order Amish eschew most modern conveniences and thrive on self-sufficiency, they are relatively isolated from the typical ups and downs of the wider economy.

Cities Step in to Foreclose
The City of Riverside, CA, is using money from the federal government to help it buy and renovate foreclosed homes. The homes are then sold back, typically to first-time buyers. Cities are stepping in to stabilize neighborhoods. Areas with multiple foreclosures create maintenance issues, and "It's demoralizing, it threatens neighborhood stability, and it will lower property values," according to Erik Strunk, community partnerships director from Glendale, AZ. By providing support for mortgages and money to do repairs, cities mitigate the damage and can bring families back into neighborhoods.

Insurance Industry Beginning to Adjust Policies to Address Climate Change

SIPs So Impressive They Sold the Company: On doing his research to build a community, Jimmy Farlow became so impressed by structured insulated panels that he bought his own SIP company in North Carolina and moved it to Blairs, VA. Improving on his experience with SIPs to build energy-efficient houses, he is now seeking funding to use polymers and energy cells in construction, which would produce reduced energy savings of as much as 90%.

Ring City Maximizes Green: South Korea is considering building a new eco-city named Gwanggyo. As envisioned by Dutch architecture group MVRDV, the city center would be designed as rings so that the areas available for plants could be maximized.

Disappearing Waste Water: "What percentage of water that goes down the drain is actually lost forever?" This was a question World Changing took on recently; a question from a reader answered by Sarah Kuck and Julia Levitt. I quibble only with a few minor points. Mass can be destroyed. That's what makes nuclear reactions so powerful. And a certain amount of water is being lost by the earth all the time as it evaporates into space. That said, it's pretty clear that the questioner had a point. Just because water goes down the drain doesn't mean it disappears, never to be heard from again. And, Kuck and Levitt's point about the cost of making it useable and carting off the remains hits that point on the head.

Mixed-Use Complex Complex to Build: The East College Street Project in Oberlin, OH, is finally under construction. But Sustainable Community Associates became somewhat reluctant real estate developers in order to overcome the many obstacles to funding, planning, permitting, and building the project. "We began what was in retrospect a fantastically foolish endeavor, but over the last three years have cobbled together a mix of public, private, and philanthropic funds and are moving through predevelopment architecture and legal work," said Ben Ezinga, one of the project founders. The project is described as a "multi-party, multi-layer financed, mixed-use, mixed-income housing and retail project", but it has the capacity to change the economics of Downtown Oberlin and can act as a model for similar projects in other locales.

Buyers Rein In Luxury Items: Kitchen and bathroom remodelers want efficient and renewable fixtures, while demand for luxury items has taken a sharp downturn, according to a survey by the AIA. Accessible and easy-to-use areas are also gaining popularity, but high ceilings are meeting resistance, as people worry about heating the extra space. Buyers are aware of the value of green products, and perhaps want to impress their neigbors with sustainable homes.

It Came From Outer Space
They may say that in a few years about electricity if startup Solaren is able to launch its power satellites. They got a boost from PG&E, which has agreed to buy up to 200 MW of power from the company at a fixed price, should it be able to put its satellites in orbit. The satellites would microwave the power to Fresno, CA, where it would be converted to electricity.

Refurbishing Existing Buildings Important for Carbon Goals
A report from the UK Economic and Social Research Council and Technology Strategy Board says that buildings will need to be radically refurbished to meet government goals. The study, "How people use and 'misuse' buildings", notes that domestic buildings release far more carbon than commercial, public or industrial buildings, and will need serious changes to approach net zero carbon. Taking on this task in Britain would keep 23,000 teams of people busy for 40 years, according to the study.

Green Volts Shifts Course
San Francisco company Green Volts announced that it has replaced the CEO and is shifting course from building its own power plants to licensing its product.

Give Me Back My Water!
Southern Nevada Water Authority wants its water back. It claims that water it sells to homeowners belongs to it after they finish using it, and they want it back to put into Lake Mead. Water returned to the lake can be taken up again, processed and resold to residents around Las Vegas, NV, which the agency claims reduces the need to take water from the Colorado River. So, the agency wants to prevent property owners from catching and recycling water they buy, and has now made it official policy to oppose graywater recycling. Manuevering may have killed an assembly bill that would have permitted graywater recycling, despite the increased efficiencies of recycling the water on site, where it doesn't have to be shipped back to the lake and then cleaned again.

New Transmission Lines Create Potential Environmental Problems
As renewable energy facilities (solar plants, wind farms and geothermal production) start to replace older technologies, they often create the need for new transmission lines, sometimes in environmentally sensitive areas. A recent agreement by Southern California Edison, rerouting transmission lines from a solar plant in the Mojave desert to San Diego around a protected State Park may be an example of things to come. The plants themselves are sometimes concerns. One proposed solar farm would cover up to 9% of New Mexico. Placing production near the consumer reduces the need for these tradeoffs.

Pennsylvania Making Energy Efficient Buildings Easier
A new $25 million High Performance Building program will provide grants and loans to construct or renovate buildings meeting standards for overall sustainability. Governor Edward Rendell hopes that the money will help reduce energy consumption, which he expects to again bump up against production limitations.

Saving Winter: Many places have plenty of cold to get them through the summer; it just arrives during the winter in the form of snow. One Canadian official (Gloucester-Southgate Councillor Diane Deans) wants her city to store some of that snow to use for cooling buildings the rest of the year. This is a proven technology that has been used in Sweden, where a snow dump is used to cool a hospital. The snow is mixed with wood chips to help prevent it from melting prematurely.

Carbondale Revises Standards: The energy efficiency code in Carbondale, CO, has served as a model for other communities, but will come under revision after only two years because some think it has become too easy for builders to meet.

Tighter Homes Endanger Indoor Air Quality
Airtight homes lower carbon emissions and significantly save energy, but require special efforts to prevent air quality problems. The tighter envelopes can trap pollutants, especially if the home is filled with synthetic building materials, which outgas harmful chemicals. Reduced air flow can also allow moisture to build up, resulting in toxic molds. To ensure proper air flow, newer ventilation fans, like those in Panasonic's WhisperGreen line, can respond to conditions and selectively expel steam and odors, while low-rate continuous ventilation removes indoor air pollutants. In climates with wider temperature variations, a heat-recovery ventilator can exchange air while retaining about 85% of the heat during the exchange.

Fire on Ice May Sequester Carbon
Clathrate hydrate, which looks like regular ice, is a lattice structure that holds methane molecules. Scientists are looking at ways to replace methane with carbon dioxide, sequestering the carbon while releaseing methane to burn. If a way can be found to pump carbon dioxide into clathrate hydrate containing rock, the methane can be captured while reducing the impact of the carbon released.

Afforable Housing Struggles to Pay for Green Features
The limited pricing for affordable housing makes it difficult for these projects to recoup investments in green features. Governments are beginning to find ways to bridge the funding gap. One example is the Massachusetts Green Affordable Housing Initiative, a program to help fund small photovoltaic systems. And the California Solar Initiative has two programs that specifically finance solar systems for existing buildings. California also has a program for solar on multifamily housing.

Energy Efficiency Raises the Rent
A report from the Royal Institute of Chartered Surveyors shows that green rental properties command 3% higher rents (per square foot) and sell for 16% more than similar non-green buildings in Britain.

Vinyl Floors Implicated in Autism
A recent study indicates that children who live in homes with vinyl floors are more likely to have autism. The likely factor is phthalates, emitted by the vinyl. The study by researchers in Sweden and the U.S. is not conclusive and was not focused on autism, but it turned up the apparent link by accident. Representatives of vinyl floor makers note that the low levels of phthalates emitted by their floors do not tend to evaporate because they have low volatility. The study suggests that more specific research is indicated.

Detroit Housing Sees Some Revival
With housing prices in Detroit hitting extreme lows, the city may be fertile ground for the build-out of sustainable homes. Gina Reichert & Mitch Cope started a mini-boom when they acquired a house for just under $2000. Others jumped in, with one couple buying a home for $100. Now Reichert and Cope have established Design 99, an architecture firm in a store front that offers design for 99¢ a minute, hoping to create an open dialogue with the general public.

Michelle Kaufmann Addresses Water Usage
Michelle Kaufmann, award-winning green architect, has released a new white paper, "Turning the Tides of Crisis: Prioritizing Water Conservation Before It's Too Late", addressing the looming water crisis.

Cuba Provides Examples of Coping With a World Without Oil: After the collapse of the Soviet Union, Cuba was left without ready access to oil. This "Special Period" led to a fundamental reorganization of food production, with a boom in urban organic agriculture. Prior to the Special Period, much farm land had been depleted by oil-based chemical fertilizers. It required careful application of manure to restore fertility. The experience may be a paradigm for dealing with peak oil, but if the pain of this experience is going to be replicated on a worldwide scale we might hope that other means are available.

China Rolls Out Subsidies for Their Solar Industry: While solar power is a small factor in power production in China, the government has begun subsidies to the solar industry. The move is seen as an effort to capture green jobs, which have increasingly become a strategic economic move. The subsidies cover about half the cost of installed solar power.

Most of these professionals believe that framing energy efficiency as an economic issue was the best way to make the case for action.

Combining Fresh River Water and Salty Sea Water Generates Electricity
Researchers have started to develop two new ways to harvest the energy potential of mixing river water with sea water. One method allows fresh water to flow across a membrane into sea water, a process that increases pressure on the salty side. The increase pressure is used to drive turbines. Another method allows positively charged sodium ions and negatively charged chloride ions to selectively flow into fresh water cells. The difference in electrical charge can then be harvested, similar in concept to tapping a battery. A prototype plant, using the first scheme, is being constructed at Södra Cell paper pulp factory in Tofte, Norway. The technology has the potential to provide a significant percentage of world power needs with a new source of renewable energy.

Dimming Skies May Impact Solar Power
New studies show that increased pollution is resulting in somewhat dimmer skies. New data has been collected over land to go with data already available over oceans. Skies in Europe, however, are getting clearer as declines in pollution there take hold. Researchers warn that proposals to use high-altitude particle release to combat global warming would also reduce the effectiveness of solar cells. This would affect crystaline cells more than flat panels and solar thermal, which react better to diffuse light. [The effect would probably be negligible. No solar shading proposal would likely reduce sunlight by more than 1%, the amount needed to combat global warming.]

California Testing Water Replenishment
How do you keep millions of people alive in a desert? That's the question California water officials must ask themselves every year. To help, Orange County has developed a Groundwater Replenishment System, which treats wastewater (that stuff from the sewers) to high quality before injecting it back into the ground. Some keeps ground water pressure high enough to prevent seawater intrusion. Other water leaks through to aquifers where fresh water is drawn for municipal water. Treated wastewater may someday be piped directly to spigots. The water, purified with microfiltration, reverse osmosis, ultraviolet light, and hydrogen peroxide disinfection, is at least as pure as water sourced from steams and wells. But so far, officials have not put it directly into the drinking supply (as in other countries). [Note: The definition of gray water in the article is wrong. Gray water is leftover wash water where the only significant contaminant is soap.]

Wisconsin Lumber Stays Around: Laws in Wisconsin are changing to allow lumber to be used locally. State building standards have prevented small sawmills from cutting locally-harvested lumber. But a change will allow these sawmills to sell directly to local homebuilders, although not to retailers. This will help reduce the embedded energy in local woodframed homes.

Green Buildings Should Avoid the Ugly Stick: Should you be able to tell at a glance that a building is green? Should green buildings have a distinct look that proclaims their sustainability? At least, a growing number of architects say, green buildings don't have to be ugly.

Trends

Out Is Out: Make room for the infill invasion, as studies confirm the growing demand for compact, infill development over suburban sprawl. Increased commuting costs have buyers looking for homes near hubs and transit stations. A study by the American Institute of Architects shows buyers believe infill homes will retain more value because their locations offer more convenient access to employment centers, commercial opportunities, and other daily household activities.

Economy Punctures Bloated Houses: Designer Russell Versaci is taking advantage of the recession to design smaller, well-built homes. He calls his style "The Pennywise House", and his "Simple Cottage Sampler" provides plans for manufactured homes ranging from 400 to 950 square feet.

Not Part of Any Trend: National Association of Home Builders unveiled its 26th annual New American Home in Las Vegas this year. While it incorporates many green aspects, including 12,000 khz worth of PV and spray-foam insulation up to R-50, some question whether it's really green. Billed as gold level under the NAHB National Green Building Program, it only qualifies under the Model Green Home Building Guidelines, not the more stringent ANSI ICC 700-2008 National Green Building Standard. And, an 8,800 square foot in the desert? No wonder it's surrounded by native plants and drought-tolerant, non-native species rather than grass!

Home Remodeling Continues: Even though remodeling has been reduced, National Association of Home Builders predicts more than $200 billion will go into remodeling this year. People who are looking for the best place to put their money are considering upgrading windows, insulation and their HVAC systems.

Upgrading Existing Homes: Window and door maker JELD-WEN lists three new trends in building: (1) affordable green options allow homeowners to move without blowing their budgets, (2) overstressed homeowners want maintenance-free products so they can use their time for relaxing, and (3) with less movement to new homes, maximizing existing space now has increased priority.

Standards

California Builders Get Behind Standards: The California Building Industry Association is endorsing two building standards: the California Green Builder program from the Building Industry Institute and the GreenPoint Rated program from Build It Green. CBIA wants to see more help to insulate and install modern window systems, rather than tougher energy standards.

New Products

Office Pops Out of the Box: Two architects have developed a green office maximizing the use of cardboard. The Nothing office uses cardboard for walls, signage, beams, tables, shelving and even stairs.

Heliostat Brings Light: Practical Solar has introduced a new heliostat that allows homes and companies to redirect sunlight for better use. The system can concentrate or spread sunlight. It is being used to beam sunlight onto the north side of buildings to light up businesses that would otherwise have to use artificial lighting.

Editorializing

Population Collides With Global Warming in the West: Scientists say climate change is shriveling the snow pack in California's Sierra Nevada. Urban sprawl has forced farm land out of production. While the recession has bought some time, officials in California cities are trying to figure out how to expand the flow when the economy picks up. Are we going to see highly-treated waste water reused in Los Angeles and San Diego?

Bay Area Mayors Unite on Green Direction
The mayors of San Francisco Bay Area's three largest cities are united on goals for fighting climate change. In a Climate Change Compact signed Friday the cities will pool their resources in developing green programs. The compact includes 10 measurable goals. The cities want to promote green jobs and green education.

USGBC Names New SVP of LEED
The U.S. Green Building Council named Scot Horst to the new position of Senior Vice President, LEED. Horst is widely recognized as a leader in the sustainable design movement and participated in a broad range of work related to Life Cycle Assessment. Rick Fedrizzi, president and CEO, said that the new position "underscores our intent to continue LEED's upward momentum as the market's tool of choice for advancing green building."

ICC-700 Encourages Better Glazing
The International Code Council's new ICC-700 standard may encourage better use of windows in buildings. Industry consultant Thomas D. Culp, Ph.D., says, "[the standard] will promote low-E in all regions [of the country], and possibly some triple glazing in the north. There are also credits for sun-tempered design, passive cooling design and passive solar heating design."

Green Education Getting Hot: Colleges and universities are gearing up to offer the best green programs they can, hoping to cash in on the green wave. Oregon State University and Portland State University are collaborating to create $1.6 million of green building research programs. Many other schools have started programs or reoriented existing environmental programs. Our Schools and Training Institutions page provides a list of the educational organizations we know that have such degrees and programs.

Getting the Green Goods: NewHome is planning to open full-service showrooms for green building needs in April, starting with a store in San Rafael, CA. Formerly a conventional store, the new superstores are intended to compete with Home Depot and Lowe's. Along with a retail website, the stores will carry about 20,000 "eco-friendly" products.

New Technique Quickens the Charge for Lithium Ion Batteries: Two scientists at MIT have found a way to radically increase the speed with which lithium ion batteries can be charged and discharged. The technique sets up tunnels through the surface of the lithium iron phosphate cathode using a thin layer of lithium phosphate glass. Batteries with lithium iron phosphate are already in commercial production. This technique could allow electric cars to charge very quickly (if the means can be found to deliver that much current to a car safely). More information here.

Better Pay for Green Energy: Gainesville, FL, has become the first U.S. city to offer higher payments for solar power than grid energy, creating an incentive to buy that is more common in Europe than the States. The city pays homeowners twice the going electricity rate, and the better rates are guaranteed for 20 years. Hawaii and other states are considering following suit.

Organic Dyes Increase Solar Cell Efficiency: Researchers at the Chinese Academy of Sciences have achieved 9.8% efficiency with the new organic dyes for dye-sensitized solar cells. The stable, solvent-free cells are cheaper to produce than previous cells.

Green Jobs Visionary Gets Job at White House
Van Jones will join the White House Council on Environmental Quality as special advisor for green jobs, enterprise and innovation. Jones was author of the 2008 best-seller, The Green Collar Economy, and founder of Green For All, an organization for creating green jobs in impoverished areas. In addition to serving on the council, he will advance the administration's energy and climate initiatives, with a special focus on vulnerable communities.

After 10 Million Years, Women Get Houses Built for Them
While there are some obvious flaws in this story, I think it's worth noting that modern consumer research has finally helped builders to find out what women (and I) have known for many years: homes need storage. When home builder NIH Homes of St. Paul, MN, started experiencing the downturn in 2006 they turned to a sales consultant for help. The result was homes designed for and marketed to women. Their new "woman-centric" homes not only have a lot of storage, but other features designed to draw in women, such as better vanities, spas, and special lighting. [Personally, I can do without the mood lighting, but there's got to be enough storage that I don't have to hide my toolbox in the living room.]

The Good Housekeeping Green Seal of Approval
After a century, Good Housekeeping is adding a second seal of approval later this year. Like the current Good Housekeeping Seal, which reassures buyers that some 5,000 existing products are fit to be used, the new seal will help buyers distinguish products that they can safely buy. This includes evaluating the product's health value and toxicity. The seal puts the organization's reputation on the line. See more information here.

$1 Million of Green Trouble: Here's an opportunity to learn from someone else's mistake. After five years of construction, neighbors of a green home project have had enough. They asked the city of New Hope, MN, to come up with a traffic mitigation plan for their cul-de-sac for when the home "goes on exhibit". Council members acknowledged that it sounded like neighbors had suffered in the execution of the project, but said any extended remodel by any of them would have resulted in much the same thing. Still, one neighbor labeled the house "a massive science project."

Man's Metal Roof Flashes HOA: A homeowners' association in West Austin, TX, is suing one of the residents after he installed a metal roof without their permission. The HOA complains that the roof reflects light in an unacceptable manner. Homeowner Joe Sigel notes that he was not asked to stop the construction of the roof until it was near completion. States are now moving to pass laws that prevent homeowners' associations from prohibiting green building practices.

California Warns of Green Scams
The Contractors State License Board has issued a Consumer Alert to warn the public about scams in "green" contracting trades. One contractor in Sonoma County, CA, has had his license revoked.

Where Do Architects Go in Economic Winter?
One suggestion is that they be put to work doing energy audits of existing federal buildings. This could put "tens of thousands of architects to work." An expansion of the AmeriCorps program to include a "Design Corps" could employ thousands more. Architects could also be hired to to catalogue federal buildings with cutting-edge building information modeling (BIM). With this data, it would be easier to respond to emergencies.

Are Radiant Barriers Doing the Trick?
Most researchers put the effect of a radiant barrier in the roof in the range of 5% savings on cooling energy costs. The Florida Solar Energy Center says that a radiant barrier with R-19 insulation in the attic performs at least as well as an attic with R-30 of insulation. But one homeowner reduced the differential between outside and inside air from about 30 degrees to about six by using a three-prong approach of a radiant barrier, better insulation, and additional eave vents with a solar-powered roof vent.

Earthen Floors Fit the Feet: The image of an earthen floor might conjure up the dusty necessity of a primitive hovel, but twenty-first century floors made from earth are soft and warm, with a durable surface. Built with proper foundation (drainage is, of course, highly important) and the right sealant (raw linseed oil is preferred as boiled linseed contains solvents and is highly toxic), earthen floors can be beautiful and very functional.

New Windows Rotate to the Seasons: Israeli researchers have developed reversible windows that can hold in warmth in the winter and keep it out in the summer. Two panes, a clear, sealed pane and a tinted one with vents, in a reversible frame allow the windows to adjust to the seasons. With the sealed pane inward, heat is kept inside; with it outward, sunlight penetrates to warm the inner pane, allowing warmth to be transfered to the room.

Windows Up for Better Energy Costs: Energy-efficient windows not only save on energy costs but make homes more comfortable and more valuable. Energy Star rated windows are twice as efficient as the average windows manufactured 10 years ago, and 40% more efficient than those required under most building codes. Coated windows can also block up to 75% of UV radiation, which helps preserve curtains, furniture and floors (which can be bleached by the sun).

Riverside Taps Green Electic
In an effort to become one of the greenest cities around, Riverside, CA, plans to get half its electricity from renewable sources by 2013. This includes pulling power from geothermal sources in Utah. The city also achieved California's first "Emerald City" status this month, after proving its long-term commitment to reaching state environmental targets on improving air quality, waste reduction, recycling, fuel use development, land conservation and energy efficiency. The award means state and private dollars for more green improvements.

Ex-Exurbs
Inland California may go back to a shallow sea, or at least to farmland, as extinct developers leave their lots fallow. Developers in Solano and Stanislaus counties have failed, leaving empty tracts. Buyers may be seeking the lower risk of cities, where high gas prices won't strand you far from a job. This is a plus for places like Visitacion Valley in San Francisco, where 1,250 homes, parks, shops and other amenities are planned.

Housing Starts Worse Than Last Year

Like Shooting Rain Into a Barrel: Euclid, OH, wants its residents to install barrels to catch rain water for their lawns and gardens. Led by Councilwoman Mary Jo Minarik, the city set up a rain barrel display in the municipal center and scheduled a workshop for 28 March 2009 to teach people how to set them up and use them. Minarik says she collects 210 gallons of rainwater for every 1/2 inch that falls on her roof. Now, if only we could get some rain to fall on California....

The Green Vanishing From Southern California Lawns (Slowly): The climate through most of California ranges from dry to desert. It's a modern miracle, then, that the state has about 300,000 acres of residential lawn, soaking up enough water for 3 million homes. Still, will folks in Kensington, CA, tolerate drought-tolerant lawns among their spreads of green Bermuda grass?

The Toughest Skeptic to Convince: Fort Worth, TX, commercial real estate broker Trey Neville wanted to build the ultimate green home. But before he could spec out a LEED Platinum house for himself he had to convince the toughest skeptic--his wife.

Changes Coming to Highway Designs: The deteriorated road system may force changes to roadway design. Some are questioning building roads to optimal standards. Is this a waste of money? The new thinking is called "Practical Design" and prioritizes spending to only achieve specific requirements. While this saves money, does it provide an adequate margin for error? We'll probably find out a few years "down the road".

High-Performance Buildings Contribute to a Greener World: The think tank RMI, in Boulder, CO, wants to go beyond LEED and design "high-performance buildings" that reduce greenhouse gas emissions. The "Cooling the Warming" initiative seeks buildings that act as giant air and water filters in which people live or work. One building under design is the "Energy Plus" center planned for Paris, France. It would have over 10,000 square meters of PV and use water from the Seine for cooling.

Importing Stick-Built Homes to Ireland: Gerry McCaughey helped convert nearly a quarter of Ireland's new homes to wood-frame by introducing factory building to the island. Traditional homes there are built with concrete blocks and brick. Capitalizing on the standardization of homes built off site and the better insulating quality of wood-frame homes, McCaughey built a major home manufacturing company and sold it to the Kingspan company in 2005. Now he has been drafted to clean up the Dublin docks, a task that will require more legal skills, it seems, than home building ones. [Note: The Oireachtas is the legislature of Ireland. Also, while wood has better insulation qualities, brick has better thermal mass properties, so the two are not strictly comparable solely on insulation values.]

Report From Developers Stirs Debate on Payback
The Commercial Real Estate Development Association released a report this week claiming that many energy efficiency goals are unattainable, and some targets not feasible. But the report is already under attack by Edward Mazria, a Santa Fe architect, who pointed out the many ways the report ignores options. "NAIOP intentionally kept out of the analysis all the readily available low-cost, no-cost and cost-saving options to reduce a building's energy consumption," according to Mazria. ["NAIOP" is the former acronym for the developers association.]

UK Prime Minister Gordon Brown visited Washington, DC, this week, bringing a global "Green New Deal" that aims to restore growth while dealing with climate change and energy security. He might be glad to escape the hammering from Liberals, Tories and other parties over his handling of the crisis, and flash mobs appearing outside RBS HQ in London. Meanwhile, Obama has sent officials to the Gulf Coast to speed up recovery from environmental disaster Hurricane Katrina, as the area languishes in its attempts to rebuild. And, in Sweden, the Minister of Trade "encouraged" Saab to go into the wind turbine business, after refusing the troubled subsidiary of General Motors financial support. But is Volvo getting favored-child status if the government provides assistance to them? No, says trade minister Maud Olofsson. "Volvo's owners, Ford, told us that they will continue to support us and are ready to take full ownership responsibilites. That separates Ford from GM, who is now just leaving Saab behind," he said.

Bay Area Homes Lap Up Rain Water
San Francisco green developer LORAX Development has installed the first residential rooftop rain-catchment system in the city. After battling the Department of Building Inspection, they added the system to a Noe Valley home, despite being told, "You can't be your own water plant." In the East Bay, Shapell Homes and others created a 600-acre community that takes net zero water. With off-site water mitigation and reductions in the on-site water needs (from 0.7 to just 0.45 million gallons of water per day), the community fits within an area of East Bay Municipal Utility District that does not have long-term assured water supplies.

A home in Minnetonka, MN, has won the Outstanding Custom Project Award from LEED, the top honor. Dubbed the "Sustainable House", the home was remodeled over a period of two years using seven teams of 278 individuals. The home contains an increadible number of features.

Twelve-Year-Old Creates New Homeless Shelter Design
Max Wallack not only designed a new homeless shelter, but he did it from waste for the Trash to Treasure contest and won $10K and a Dell laptop. His "Home Dome" looks like a yurt, but it's made from clear plastic, wire and packing peanuts. I bet it costs a lot less than $10K to build. (With video clip.)

Would You Buy a Used Car, Er, Recycled Home From This Man?
How about if you knew you could get it for $95 a square foot? Rob Boydstun, formerly of Boydstun Metal Works and now a new home manufacturer with the startup Miranda Homes, has found a way to turn six car carcasses and some other materials into a brand new home that may be hard to tell from any others, except that it is extremely energy efficient. Framed in rigid foam and slattered in sprayed foam, their envelop seal allows them to reduce air exchanges to a mere 2-1/2 per hour. Boydstun and his team totally reworked the construction process to move as much production indoors as possible and eliminate waste, using only a five-person team and only 45 days to construct the home. They expect to have additional models available soon.

Portland Home Shows Green Doesn't Always Carry a Premium: Oregon developer Emilia Sibley is finding it difficult to sell her new energy-efficient homes, despite the green buzz. With homes in the mid-300s, she finds buyers are still more interested in traditional features, such as layout and finishes. Part of the problem may be that assessors still don't have enough comparables to show that green features carry a premium. But that may change as buyers increasingly take the total cost of ownership into account.

The Legendary $1 per Watt: A new solar panel is being manufactured for $1 per watt, a number associate with grid parity. While the total price would have to reach $1 per watt, solar cells at 65-70 cents per watt would make that feasible.

Economy Takes Its Toll on Home Design Magazines
House & Garden, In Style Home, Blueprint, Home magazine and many more have either shuttered or find themselves fighting for survival as a combination of 24-hour TV shows, the Internet and oversaturation have put extreme financial pressure on the market for magazines about homes.

Blended Green
The firm Coolerado has created a new device that combines air conditioning with solar power to get a solar-powered air conditioner with spare voltage for your home or business. Calling it an air conditioner doesn't do it justice, since it uses no circulating coolant, just the evaporative cooling of water, and has only two moving parts. Unlike a swamp cooler, the water is evaporated in a separate air flow from the working air delivered to the building, as explained in their video. The water ladened air (called "saturated") is routed to the undersides of the PV panels, cooling them. In doing so, it raises their efficiency on hot days, where excessive temperatures could sap as much as 30% off their power. The combined system takes advantage of this natural dynamic to lower the power requirements of the air conditioner to about 1/10th what a regular air conditioner would use. However, the system can use as much as several gallons of water per day.

Solar Power Approaching Grid Parity
Long the goal of solar power, cheaper chips may drive prices down to where solar power can compete with power off the grid. If solar panels can be installed and operated more cheaply than grid power, the economics change to favor installing solar over building new power plants, even in the absence of subsidies. The solar industry could see $1 per watt by 2012.

Cardiff New Home for Solar Power
Does your solar cell work well in Wales? If Bob Hertzberg's solar-power company, G24i, makes a success of their new facilities in Cardiff, they may prove that solar will work without sunny days. Hertzberg picked Europe in part because he says regulations are less onerous, and he can still get to finanical markets in London in two hours by train. He expects his solar strips, dye-sensitized thin-film that only capture 3% of incident light, to work as well in the haze as crystaline silicon. The strips require so little energy to make that the factory will be powered by wind turbine. Devices produced with the strips will probably be sold in the third-world, where new micro-financing is opening up markets.

Efficiency Tops List of Energy Resources
Energy efficiency in the U.S. is "widely abundant" and may offer "more potential than any other known resource". It can "provide thousands of high-paying jobs" and comes with little environmental cost. It's "always 'on,' ready to be 'dispatched' without delay or intervention by energy providers". Physicist Amory Lovins calls energy efficiency "doing more with less through smarter technologies". The Obama Administration's goal is to reduce electricity demand 15% from projected levels by 2020. But existing laws and policies are significant barriers to increasing efficiency.

Solar Power Prices May Drop
Keith Johnson, posting on the WSJ website, says, "Solar power might be on the cusp of getting a lot cheaper", noting a study from Lux Research that says solar prices will drop as supply outstrips demand. Prices have already fallen significantly over the last decade. A report by Ryan Wiser, Galen Barbose, and Carla Peterman of Berkeley Lab's Environmental Energy Technologies Division says that they declined from $10.50 per watt in 1998 to $7.60 per watt in 2007 in constant 2007 dollars.

Energy Secretary Chu Outlines Climate Change Scenario
Secretary Steven Chu said that California's agriculture could turn to dust and its cities disappear if climate changes as predicted. "I don't think the American public has gripped in its gut what could happen," he said, adding, "We're looking at a scenario where there's no more agriculture in California. Senator Barbara Boxer and Representative Henry Waxman have separate proposals in Congress to cut greenhouse emissions. California's snowpack, the source of much of the state's water supply, is near 60% of normal levels this year, after a warm winter with little percipitation.

Alleys Provide Green Opportunities
In LA, alleyways account for more than 900 linear miles of pavement. They get little use, compared to other, highly-utilized parts of the city. "They're basically just sitting there," said Jennifer Wolch, professor at USC's Center for Sustainable Cities, which has published a series of reports on them. She wants to get green alleys on the city's official agenda. Alleys offer incredible opportunities for greening up the city, but they need careful planning. Previous attempts have had mixed results.

Radon Facts Hidden in California
Linda Kincaid says that realtors in California sometimes hide the fact that about half of California counties have radon in the EPA Radon Zone 2, which averages 2-4 pCi/L of indoor radon. The EPA suggests you fix your home if you have levels above 4 pCi/L (picocuries per liter). One home in Sunnyvale, CA, tested 29 pCi/L and one in Los Gatos 56 pCi/L. A $5 kit will allow you to test your home and fixes are generally not very expensive. The EPA estimates that radon causes 21,000 deaths per year, more than drunk driving.

CIFs Reduce Need for Furnaces in Illinois: Contractor Mark Hoerr of Don Hoerr and Sons, who learned to put up a concrete insulated foam house, said that it took about 30% longer to build than a similar stick framed house on their first attempt. But, CIF supplier Ken Senffner says that CIFs supply energy savings of about 70% over traditional wooden stud construction, due to heating and cooling from the earth. "The walls act like geothermal furnaces. [This] house has two furnaces in the main part of the house and one unit upstairs.

U.S. Now World's Top Wind Energy Producer
No jokes about how we're now bigger blow hards than Germany. Accoring to the Global Wind Energy Council in Brussels, the U.S. is now tops in wind turbine capacity with 25 GW, just ahead of Germany (24 GW). U.S. wind power capacity climbed 50% last year, and is expected to climb again with incentives favored by President Obama.

Not Enough Progress Says GreenBiz Assessment
Only a few areas made progress in this year's GreenBiz Index, which assesses progress on 20 indicators. Three are sinking, according to the report, available free here (registration required). Carbon intensity (emissions of greenhouse gases per unit of GDP), employee telecommuting (number of U.S. teleworkers), and E-Waste (percentage of recovered electronic equipment with hazardous components) all got low marks. In addition, scientists at the World Economic Forum reported that clean energy investments need to triple to $515 billion a year to stop planet-warming emissions. Fortunately, a study by McKinsey and Company indicates that an investment of less than 1% of of world GDP would be sufficient to keep global warming below 2 degrees Celsius by 2030.

Retrofitting Homes Much Better at Reducing Carbon Than Improvements to New Homes
A study for the California Homebuilding Foundation shows "retrofitting existing homes with energy-efficient features is four to eight times more carbon- and cost-efficient than adding further energy-efficiency requirements to new housing". Both methods reduced carbon generation. A $10,000 retrofit of a 1960s home could save 8.5 tons of carbon while a 35% improvment over current state requirements would cost about $5,000 and would reduce emissions by 1.1 tons.

Aluminium Gallium Nitride Prevents LED Production Cracks: LEDs made from gallium nitride cannot be grown on silicon wafers because the GaN shrinks twice as fast in cooling as silicon. But researchers at the University of Cambridge have discovered that layers of aluminium gallium nitride slow down the rate of shrinkage, so that LEDs made with it can be grown on silicon. This may eventually make LEDs price-competitive with CFLs.

Sensible Remodeling for Recessions: The days of house flipping are over. But there are still sensible remodels to do, even with lower home prices and scarcer loans. Changes that reduce the energy consumption of the home may still make sense. Start by checking out the efficiency of air ducts and general leakage in the envelope of your home. Evaluate your windows to see if replacing them could save on heating and cooling costs, or whether adding insulation could pay you back. If these aren't enough, this article suggests looking into wind turbines and geothermal systems, both of which were added to the tax credit rolls this year.

"We're Doomed to Global Warming, So Let's Give Up": It's not an exact quote, but it's the gist of an editorial by Paul Danish in the Boulder Weekly. A study recently published in the Proceedings of the National Academy of Sciences suggests that 450 ppm, CO2 levels recommended by the IPCC, could only be reached if we didn't build any more fossil fuel power plants and "the world's automobile fleet, which is growing by leaps and bounds, could burn no more oil than it currently does". "Both developments seem improbable," says Danish. If true, we are probably past fixing the problem by reducing greenhouse gas emissions. While Danish abandons hope, others believe that some of the sun's radiation could be blocked. But that would require shields in space, an unlikely event given the political decision process. Perhaps Danish is right: "Climate change is going to happen whether we like it or not. Learn to live with it."

Alternative-Alternative Energies Getting a Look
As biofuels, solar and wind power become more mainstream, other technologies step up to take their place on the "fringe". Even technologies that were beyond the fringe, such as solar thermal and thin-film solar, are starting to see applications. Moving up to the fringe are technologies like DIY electrical car kits, next-gen batteries, cellulosic ethanol, algal fuel, ocean/tidal energy and natural gas conversion.

Broken Promises in Green Development
A green community planned for St. Peters, MO, has failed after buildings already under construction in Highland Park had to be demolished. After the developers failed to complete the buildings, they became eyesores, which the city has ordered owners to tear down. The weak economy has also caused net-zero homes in Issaquah, WA, to be put on hold pending about $2 million in financing. Project manager Brad Liljequist said, "The day the stock market dropped 800 points was the day of our groundbreaking".

Production Tax Credits Crucial to Wind Power
The Production Tax Credits are crucial to sustaining the development of wind power in the U.S. When the credits drop out, as they did in 2000, 2002 and 2004, capacity installed drops to almost zero. Steady funding for alternative energy is a dominant factor in keeping these industries alive during fluctuations in the market as they grow to competitiveness.

California Benefits from Energy Efficiency
Saving energy has allowed Californians to shift money to other uses, making the state more prosperous while adding jobs. A new report by Next 10 shows that "cutting energy bills let California consumers and companies spend their cash on other things, and helped create 1.5 million jobs". Per capita greenhouse gas emissions in the state dropped 10% since 1990. Between 2005 and 2007, green jobs grew at 10%, versus the 1% growth overall in jobs.

New Renssalaer LED Reduces Polarization Mismatch
Renssalaer Polytechnic Institute has announced a new type of LED light that is about 20% more efficient than current LEDs. The advantage comes by reducing the efficiency droop with a polarization-matched active region. Mismatched polarizations was leading to electron leakage at high energy densities.

Sundried Dry Wall
A new Southern California startup (CleanBoard) plans to make gypsum dry wall using solar furnaces, rather than ovens powered by traditional energy sources. Similar in design to solar-thermal plants, a heat collector will heat transfer fluid that will then be used to heat drywall ovens up to 200 degrees Celsius. Material will come from construction waste and the calcium sulfite that's a byproduct of coal-fired power plant smokestack scrubbers. CleanBoard will provide competition for Serious Materials, which uses a low-heat chemical process to make its EcoRock drywall.

California Home Builders Get Ahead of Regulation
The California Building Industry Association decided that cooperation and consensus was the sensible way to handle inevitable changes to building codes.

Find Yourself Living at the Mall?
Victor Gruen, the man credited with inventing the mall, intended it as a community center. It should be "a car-free haven" that includes everything you need--including housing. The traditional mall, however, has turned into an enclosed shopping center, a concept that has all but died with only one being built this year. Instead, "lifestyle centers" are replacing malls as the renovation of choice. (One is currently replacing Sunnyvale Town Center in downtown Sunnyvale, CA, restoring the city grid and opening up the space to shops, restaurants and condos.) De-malled malls include Belmar, in Lakewood, CO; Cottonwood Mall, in Holladay, UT; Natick Mall at MetroWest near Boston, MA; Coconut Point, in Estero, FL; Firewheel Town Center, outside Dallas, TX; South Park, in Charlotte, NC; The Domain in Austin, TX; and, Reston Town Center, near Washington, DC (all covered in the article).

Solar Power Finally Reaching Parity
Sempra Energy of San Diego is completing a 10 MW solar farm in Nevada that can produce power at a cost of $.075/kw-h, according to a veteran analyst. Experts calculate grid power now costs an average of $.09/kw-h. The company would not confirm the costs, for competitive reasons. The panels were produced by First Solar, which says it has cut cost of manufacturing by 67% over the past four years. Meanwhile, Perpetual Energy Systems has activated four new PV installations for wineries, including a 1.34 MW system at Beringer Vineyards.

Stimulus May Include Mortgages in Exchange for Green Upgrades
There are hints the Obama Administration might use the stimulus package to provide mortgage relief in return for green upgrades and invest in residential green technologies. One proposal, by Architecture 2030, would lower mortgage rates for homeowners achieving significant energy savings. Geared to generate 8.5 million new jobs over a two-year period, the proposal may be gaining traction in Washington. Lisa Margonelli of New America Foundation recommends the government fund a mass home weatherization program for families with incomes less than $75,000. The Department of Energy already has someone with a mandate to weatherize all homes in the country, but this specific proposal would probably add funding.

Cities Focus on Green Initiatives
Many cities are focusing on green initiatives, even if they sometimes don't sense the urgency. In Palo Alto, CA, Peter Drekmeier is the favorite to become the new mayor. On the city council, he helped drive the city's green building ordinance and zero-waste plan. He wants the city to be more locally self-reliant, but he will face challenges during the economic downturn implementing green initiatives if they cost more today even if they save in the long run. In Eureka, CA, the city council wants to create a green team from existing staff to help make the city a greener place to live and do business. And, in Pittsburg, CA, the mayor wants to incorporate green thought into the normal course of business. "I think that most people are pretty well-convinced that this climate business has some validity; it might not be a crisis," she said. "Whatever we can do to efficiently make these changes, why shouldn't we do them?" Admirable, but Pittsburg is effectively at sea level. So, get a move on, Mayor Parent!

Green Not a Guarantee of Sales
Recently, green homes have been selling when their traditional counterparts sat on the market. But Meritage Homes in Vacaville, CA, have seen a slowdown in sales of their Encore homes and is re-evaluating plans for new green communities. Still, Phoenix, AZ, homebuilder Ed Gorman sold out his comparatively expensive "Galleries at Turney" homes, which are $700,000 and $850,000 for the 2,000-square-foot units. Despite being more expensive than homes in the same neighborhood, these LEED-certified homes are about 50% more energy efficient than most homes their size. Shea Homes is also putting green projects on hold, as the market softens, but they still showed initial success with Trilogy communities (in AZ, CA, FL, and WA), which sold better than traditional homes.

Winter Bring Woes to Renewable Sources
Winter is testing the commitment of home owners to their green options. In winter, solar panels get less sun and can be blocked by accumulated snow. Since panels are wired in series, even one blocked cell can shut down a panel. Wind turbine blades can ice up, either stopping them or throwing sheets of ice off as they spin. And water turbines are susceptible to ice buildup, as well. However, brilliantly clear, sunny days with the sun reflecting off the snow, and the colder temperatures (which allow solar cells to operate more efficiently) can result in better power generation in some cases than in summer. Shovel those walks and squeegee those snow panels!

Design/Build Teams Quicken Green Homes
For designers struggling to get builders to implement their sustainable plans, the option of moving into construction allows them to move more quickly. Chris Redmond of Little Green Homes in Portsmouth, NH, decided to include building to his design service after finding builders "unable or unwilling to implement his sustainable designs." Kevin and Hardy Wronske of Heyday Partnership in Los Angeles also design and build green homes, and are creating the first small lot LEED-certified subdivision in the city of Los Angeles.

Polystyrene Recycled for Building Materials in Sacramento
Verde Development expects to lease facilities in Sacramento to manufacture building blocks from recycled polystyrene. The 4-foot interlocking blocks have channels for Rebar and concrete, to give walls more strength. Currently, only builders where International Code Council approval is not necessary have been able to use the material. However, similar technology has been in eastern Europe for decades. It is 3-5% more expensive than a wood-frame building, but is fire and mold resistance.

And since conventional, chemical fertilizer release soil carbon into the atmosphere, organic farming helps sequester more carbon in the soil. (Unfortunately, this won't solve global warming because the earth's human population is too large to live totally off organic farming.)

Will Weeds Choke Us as CO2 Rises?
The International Herald Tribune reports on research by scientists at the Agriculture Research Service of the U.S. Department of Agriculture on the response of weeds to rising CO2 levels that come with global warming. The news is not good. However, there are a few options for using weeds to help respond. For example, while kudzu has already migrated up to central Illinois and by 2015 could reach Michigan's Upper Peninsula, it is as much as 50 percent starch by weight, and could be ideal for ethanol production. Also, genetic material from weeds (and wild cousins of crops) has been used to help food crops overcome diseases and pests.

Solar-Powered Homes May Be the Bright Green Spot for Builders
With financial markets in the tank, recent legislation in the U.S. has sent "a positive jolt to one of the economy's darkest sectors: homebuilding." Surveys show that solar systems were outselling others by as much as 2:1 in 13 California communities before the crash, and solar-powered homes are set to peak. Consumers are recognizing the value as utility bills increase, and solar homes resell for a premium of up to 5%.

Overall Economic Conditions Worsen for Alternative Energy
Despite political interest in alternative fuels, the recent plunge in oil prices and the freeze-up in credit markets have been damaging efforts to bring alternative energy systems on line. Stock in alternative energy companies have fallen faster than the market. VC financing for experimental techniques has been drying up. VC financing this year could be half the 2007 total. Natural gas is dropping toward $6 per thousand square feet, making even wind energy uncompetitive and solar "unfathomably expensive". Renewable energy still has a large investment (about $148.4 billion last year), although the total may retreat a little this year.

Silicon PV Finally Obeys Moore's Law
Generally, since PVs were introduced in the 1960s, end prices have dropped only about 6% per year. However, the last couple of years have seen a marked reduction in costs which may allow prices to reach parity with the grid in six years. IEEE reported this summer that "global PV production has been increasing at a rate of 50 percent per year, so that accumulated global capacity doubles about every 18 months. The PV Moore's law states that with every doubling of capacity, PV costs come down by 20 percent." PV costs are only one component of price, but a very significant component.
