Large batteries could be used for storing excess power from the electrical grid for future use.
New Stanford University research could point the way to large-scale, long-lasting power grid batteries. These kinds of batteries would be especially useful for making technologies like solar and wind power more practical, allowing vast amounts of storage to be stored [...]

Windstalk
Wind turbines are an increasingly popular way to generate clean energy with large-scale wind farms springing up all over the world. However, many residents near proposed wind farm sites have raised concerns over the aesthetics and the low frequency vibrations they claim are generated by wind turbines. An interesting Windstalk concept devised by New York [...]

The industrial whoosh-and-whoop of the 123-foot blades is making life unbearable for some.
Like nearly all of the residents on this island in Penobscot Bay, Art Lindgren and his wife, Cheryl, celebrated the arrival of three giant wind turbines late last year. That was before they were turned on. “In the first 10 minutes, our jaws [...]

There are more than 100 giant turbines in the Thanet wind farm.
Arranged in formation like an advancing army, this is the world’s biggest offshore wind farm.  The array of more than 100 giant turbines towering over the North Sea will be switched on today off the coast of Kent.

Future wind-turbine farms
The Yokohama Renewable Energy International Exhibition 2010 earlier this month revealed some visually spectacular new designs for wind turbine technology. The Wind Lens has the potential to triple the amount of electricity produced by offshore turbines according to experiments. Kyushu University professor Yuji Ohya spoke of the merits of the 112-meter diameter structures [...]

Winning The Power Battle With Wind?

And you thought that 1,000 megawatt wind farm planned for Lake Erie was going to be huge. Terra-Gen Power recently secured a staggering $1.2 billion in construction financing, which it fully intends to use on 3D projectors, PlayStation 3 consoles and parts necessary to build America’s largest wind farm. Granted, [...]

Cornell University Vibro-Research Group
As a renewable energy resource, wind has lots going for it – but one major downside is the cost to set up the wind turbines themselves, not to mention the problematic visual impact and the noise pollution it generates (often likened to a small jet engine, especially for those living close by). [...]

The bladeless wind turbine (left), and  the stack of disks (right) which rotate and are connected to a shaft.
A bladeless wind turbine whose only rotating component is a turbine/driveshaft could generate power at a cost comparable to coal-fired power plants, according to its developers at Solar Aero. The New Hampshire-based company recently announced its patent on [...]

Colorado’s governor has signed into law a bill requiring 30% of the state’s energy mix come from renewable sources by 2020.
In one of the boldest renewable energy standards set thus far, Colorado’s governor Bill Ritter has signed into law a bill requiring 30% of the state’s energy mix come from renewable sources by 2020. Which [...]

Wind farm
Wind power has emerged as a viable renewable energy source in recent years — one that proponents say could lessen the threat of global warming. Although the American Wind Energy Association estimates that only about 2 percent of U.S. electricity is currently generated from wind turbines, the U.S. Department of Energy has said that [...]

Both China and Africa have incredibly ambitious plans for massive energy projects sourced from the sun or wind, but India may beat them to the punch with the colossal project they have in the works. A consortium has formed between Airvoice Group and Satluj Jal Vidyut Nigam to build a 13 GW green energy plant [...]
