Wind power capacity grew by 31 percent globally in 2009, with the steepest rise occurring in China, according to a new study.

About 37.5 gigawatts of capacity were added last year, boosting the total capacity worldwide to 157.9 gigawatts, says the Global Wind Energy Council, an industry trade group based in Belgium.

The growth occurred despite the weak global economy as major nations made renewable energy a priority of their economic stimulus plans, said Steve Sawyer, the council’s secretary general.

Windation Energy Systems has developed an urban-wind rooftop turbine designed for commercial and industrial buildings. Billed as “permit-ready” and “bird safe,” Windation’s 5 kW turbine resembles a commercial AC unit and leverages a proprietary vacuum system to purportedly amplify wind speed and boost energy output.  The company’s first installation is expected this quarter in Palo Alto, CA.

CleanTechies aimed four questions at CEO and founder Mark Sheikhrezai.

Many green industry professionals and career changers are interested in clean tech conferences and alternative energy events. You can find many upcoming green tech events and clean energy conferences in the United States and worldwide in the CleanTechies Events Calendar, but how do you make the most out of your attendance? No matter whether it’s an event on energy efficiency, solar energy, wind energy, green building or sustainable transportation, there are a few things common to each that will help YOU make your participation a success.

Just in time for your next clean tech event or alternative energy conference, here are our tips:

For years now, many members of Congress have insisted that cutting carbon emissions was difficult, if not impossible. It is not. During the two years since 2007, carbon emissions have dropped 9 percent. While part of this drop is from the recession, part of it is also from efficiency gains and from replacing coal with natural gas, wind, solar, and geothermal energy.

The United States has ended a century of rising carbon emissions and has now entered a new energy era, one of declining emissions. Peak carbon is now history. What had appeared to be hopelessly difficult is happening at amazing speed.

For a country where oil and coal use have been growing for more than a century, the fall since 2007 is startling. In 2008, oil use dropped 5 percent, coal 1 percent, and carbon emissions by 3 percent. Estimates for 2009, based on U.S. Department of Energy (DOE) data for the first nine months, show oil use down by another 5 percent. Coal is set to fall by 10 percent. Carbon emissions from burning all fossil fuels dropped 9 percent over the two years.

The U.S. government has identified 4,100 contaminated industrial sites, covering more than 5 million acres, suitable for building wind, solar, and geothermal power installations.

With concern about renewable energy projects being built on pristine lands, the construction of wind and solar arrays on idle industrial “brownfields” could be an ideal solution, according to federal officials.

The Daily Climate reports that the U.S. Environmental Protection Agency and the National Renewable Energy Lab will begin conducting detailed studies of some sites this month and will hold five workshops with state and local leaders, renewable energy developers, and conservation groups to discuss constructing alternative energy installations on brownfields.

A growing number of U.S. colleges and universities supported green initiatives during the last year despite declining endowments, according to a report released by the Sustainable Endowments Institute.

Twenty-six of 332 schools evaluated in the College Sustainability Report Card received the highest-possible grade of A-minus through sustainable management of campus operations and endowment practices.

Now in its fourth year, the College Sustainability Report Card evaluates schools in nine categories, including climate change and energy, food and recycling, and green building.

An amazingly high percentage of people who live down the Mid-Atlantic Seaboard from New York to Virginia want wind turbines off their coast.

Even if they can be seen from the shoreline, 67 percent support off-shore wind power, according to a new  poll of coastal residents of New York, New Jersey, Delaware, Maryland, and Virginia .

If the turbines are out of sight, the level of support goes up to an astounding 82 percent.

Sustainability advocates long ago adopted the mantra “buy local” to limit the carbon footprint of the goods purchased. Distributed energy that’s closer to the end user through smaller solar and wind power, is having an impact on the energy sector. The next industry to become more geography-centric in purchasing will be transportation.

The automotive and petroleum industries in the United States are also relatively centralized as well. While the largest companies have U.S. central offices, the supply strings are often pulled from far away places. But as electric vehicles and biofuels ramp up, their influence with local consumers and partners will become more significant.

The United States has entered a new energy era, ending a century of rising carbon emissions. As the U.S. delegation prepares for the international climate negotiations in Copenhagen in December, it does so from a surprisingly strong position, one based on a dramatic 9 percent drop in U.S. carbon emissions over the past two years and the promise of further huge reductions.

Prominent among these carbon-cutting initiatives are stronger automobile fuel-economy standards, appliance efficiency standards, and the potential to heat, cool and light buildings with carbon-free sources of electricity.

On the supply side are efforts supporting the development of U.S. wind, solar and geothermal energy resources.

NPR’s Morning Edition recently aired this story, a variation on a theme that I have written about in the past on CleanTechies and in scholarly work: green backlash against renewable power. The Morning Edition piece focused on the land use implications of renewables, noting that it takes a lot more land to generate a terawatt of solar, wind or biofueled electricity than of coal or natural gas power.

True enough. But, for me, it all comes down to the threshold question: do you believe the worst-case climate scenarios? If your answer is yes, and you have the courage of those convictions, then you realize — as I have — that we have no choice, and no time to dawdle. People who answer that question affirmatively know that the paradigm shifts in energy production and consumption that are necessary if we are to have any chance of righting our climatological ship will face knee-jerk opposition and demagoguery from opponents (s, e.g., the spring time bloodbath over the Waxman-Markey bill). A movement that remains — however gallingly — on such tenuous footing cannot afford to endure the additional obstacle of in-fighting over policy nuances. To twist a familiar and over-used metaphor:
