WIND POWER WITHOUT THE BLADES: BIG PICS

A new assessment of wind energy in India by Lawrence Berkeley National Laboratory has found that the potential for on-shore wind energy deployment is far higher than the official estimates -- about 20 times and up to 30 times greater than the current government estimate of 102 gigawatts. This landmark finding may have significant impact on India's renewable energy strategy as it attempts to cope with a massive and chronic shortage of electricity.

Air turbulence from giant turbines causes air temperatures to rise around wind farms, scientists say.

Researchers including Associate Professor Liming Zhou from the State University of New York examined conditions around 2,358 turbines at four Texas wind farms.
