The world's biggest gas-guzzling nation has limits after all. After seven decades of mostly uninterrupted growth, U.S. gasoline demand is at the start of a long-term decline. By 2030, Americans will burn at least 20 percent less gasoline than today, experts say, even as millions of more cars clog the roads. The country's thirst for gasoline is shrinking as cars and trucks become more fuel-efficient, the government mandates the use of more ethanol and people drive less. "A combination of demographic change and policy change means the days of gasoline growing in the U.S. are over," said Daniel Yergin, chairman of IHS Cambridge Energy Research Associates and author of a Pulitzer Prize-winning history of the oil industry. This isn't the first time in U.S. history that gasoline demand has fallen, at least temporarily. Drivers typically cut back during recessions, then hit the road again when the economy picks up. The Great Recession was the chief reason demand fell sharply in 2008.
NorthWestern Energy, a provider of electricity and natural gas, has entered into a memorandum of understanding to purchase 25MW Spion Kop wind project to be developed by Compass Wind, a community-based wind project developer, in central Montana.
The Wattner Group, a developer, financier and operator of solar power plants, has procured 12MW solar park in Sietzsch, located a few kilometers from Leipzig airport in Germany.
Csun Manufacturing likely will see consolidated revenues grow 20-30 percent in 2011 according to company president Webber Wong. The growth is expected to be driven by rising demand from the semiconductor, solar and touch screen panel segments.

While the future energy needs of the planet will undoubtedly be met with a combination of technologies, many believe that solar - in the form of photovoltaic (PV) cells - is the only renewable energy source with the capacity to make a significant impact on global energy production.
Energy Roofing Systems recently announced plans to develop the first commercial solar PV system in North Georgia. The 20kW project was made possible through federal and state clean energy tax credits that cover 65% of the cost. The company also has plans to help many local businesses qualify.

The increased construction of desalination plants due to the steady fall in the cost of several key technologies for seawater-to-freshwater conversion is projected to generate a cumulative capital investment of $87.8bn worldwide from 2010 to 2016, says a report from Pike Research.
Deepwater Wind, a company based in Providence, Rhode Island, has drawn up plans for what could be the largest wind farm in U.S. waters, the company announced last week. The proposed farm would generate a huge 1,000 megawatts of power and would be located 18 to 27 miles off the coast of Rhode Island and Massachusetts at a depth of 52 meters—considerably deeper than any other large scale wind project to date. By moving into deeper waters, turbines can harness stronger, more sustained winds. And the massive turbines the company plans to use—each capable of generating more than 5 megawatts of power, with blades rising 150 meters above the water's surface—will be nearly invisible from shore, thereby avoiding potential legal battles with coastal communities that perceive the turbines as eyesores. Four-legged steel platforms rising from the seafloor will allow Deepwater Wind to operate in depths more than twice those of conventional steel "monopole" wind turbine platforms. As water depth increases, the diameter of monopoles must increase exponentially, making them uneconomical in water deeper than about 20 meters. By using a four-legged design, company officials say they will be able to work in depths that were previously prohibitively expensive.
