The American Wind Energy Association (AWEA) released their 20% Wind Report Card on July 8, following up on a study in which the Department of Energy proposed a goal where 20 percent of U.S. electricity comes from wind energy by 2030. The AWEA gave the overall U.S. push for wind power a “solid B”—high marks from an advocacy group that grades U.S. infrastructure. The highest letter in the report was an A- awarded for “Technology Development.” This is no big surprise—for years now, the government, alternative-energy researchers and entrepreneurs have been putting time and money into making better tech for cleaner, more efficient energy production. Here are 10 wind turbine designs that push the limits of the current design and may help the U.S. get back to being an A student by 2030.

Four 6,000 gallon tanks hold water gathered from the roof; a wind turbine and photovoltaics generate electricity for 14 batteries that hold a week's worth of electricity (do they have longer nights in Australia?) LED lighting, passive solar design, in an elegant modern envelope. As Dwell says, none of the "down-on-the-alfalfa-farm nuts and berries aesthetic associated with sustainable architecture."

With energy prices going through the roof, an alternative lifestyle powered by solar panels and wind turbines has suddenly become more appealing to some. For architect Todd Bogatay, it has been reality for years.

When he bought this breezy patch of scrub-covered mountaintop with views to Mexico more than two decades ago, he was one of only a few Americans with an interest in wind- and solar-powered homes.

Now, Bogatay is surrounded by 15 neighbors who, like him, live off the electricity grid, with power from solar panels and wind turbines that he either built or helped to install.

The economy is hovering somewhere between catatonic and hebephrenic, and funding for the big plans that green tech companies laid in 2008 might be a lot harder to come by in 2009. Recessions haven't always been the best times for environmentally friendly technologies as consumers and corporations cut discretionary spending on ethical premiums.

Still, green technology and its attendant infrastructure are probably the best bet to drag the American economy out of the doldrums. So, with the optimism endemic to the Silicon Valley region, we present you with the Top 10 Green Tech Breakthroughs of 2008, alternatively titled, The Great Green Hope.

However, a couple of sacred cows of environmentalism also come under the spotlight. Goodall questions, for example, whether organic agriculture can really help feed the world – arguing that yields are only just over half what can be produced through other methods, and with meat consumption, biofuels demand and populations rising, organics will need to step up to the plate if it is to be part of the solution.

Author/engineer William H. Kemp, who is a leading expert in small- and mid-scale renewable energy technologies, designed and built his own off-grid home. The result is a house that has all the standard “middle-class” creature comforts while using less than five times the total fossil-fuel energy of the average North American house.

The Renewable Energy Handbook focuses on the unique requirements of off-grid living and contains chapters on energy conservation; heating and cooling; backup power; domestic water heating; wireless communications; photovoltaic, wind, and microhydro energy generation; battery selection; and inverters.
