SustainX builds 1.5 MW isotherm compressed air energy storage system
Vestas says record powerful wind turbine in operation
Danish wind technology giant Vestas said on Thursday that the world's most powerful wind turbine has begun operating, sweeping an area equivalent to three football fields.
Island channel could power about half of Scotland, study shows
Renewable tidal energy sufficient to power about half of Scotland could be harnessed from a single stretch of water off the north coast of the country, engineers say.
German energy giants pull plug on conventional power
German power company RWE is shutting six domestic plants and rival E.ON is threatening to relocate to Turkey as the sector tots up the cost of the government's energy policy turnaround.
Offshore wind farms could tame hurricanes before they reach land, study says
For the past 24 years, Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford, has been developing a complex computer model to study air pollution, energy, weather and climate. A ...
Electric-car Nemesis at top speeds is record-breaker
Bats may be mistaking wind turbines for trees
Certain bats may be approaching wind turbines after mistaking them for trees, according to a study to be published in the Proceedings of the National Academy of Sciences.
Active power control of wind turbines can improve power grid reliability

Wind farms can provide society a surplus of reliable clean energy, study finds
The worldwide demand for solar and wind power continues to skyrocket. Since 2009, global solar photovoltaic installations have increased about 40 percent a year on average, and the installed capacity of wind ...
Smart anti-icing system for rotor blades
In very cold climate zones, the wind can blow with tremendous force. But wind turbines have rarely been built in these regions up to now. The risk of ice formation on the rotor blades is just too high. But ...
Improved structural support for wind turbines could lead to 100% greater efficiency
(Phys.org)—A University of Cambridge's Department of Engineering study suggests that offshore wind farms could be 100 per cent more efficient in terms of energy payback if manufacturers embraced new methods ...
Wind power—even without the wind
Offshore wind could provide abundant electricity—but as with solar energy, this power supply can be intermittent and unpredictable. But a new approach from researchers at MIT could mitigate that problem, ...
