Normally, bare metal sliding against bare metal is not a good thing. Friction will destroy pistons in an engine, for example, without lubrication.
Small wind turbines promise a decentralised and clean energy source, but what can be done to make them more cost effective? At the moment, better use of feed-in tariffs is recognised as a potentially effective tool for boosting ...
European researchers said Tuesday they had developed a cheaper and more efficient superconducting tape which could one day be used to double the potency of wind turbines.
Strong winds and stormy seas have helped turn the Shetland Islands in the North Atlantic into a European renewable energy giant, producing more power than it knows what to do with.
North Carolina's first large-scale wind farm is fully operational despite efforts by some of the state's most powerful politicians to shut down the $400 million project as a possible national security threat.
Local authorities approved the largest offshore wind farm in the United States on Wednesday, to be located near Long Island and capable of powering some 50,000 households.
The Pentagon says it disagrees with Republicans in North Carolina who claim a $400 million clean energy project slated to power data centers for Amazon.com Inc. poses a threat to national security.
A New York utility is set to vote later this month on a plan to construct an offshore wind farm off eastern Long Island.
Small wind turbines, for domestic and small scale commercial use, are currently relatively expensive and struggle to compete with solar solutions. The key to increasing their competitiveness is bringing down their cost and ...
Study provides new insights into fluctuations of wind energy, with implications for engineering and policy
The amount of energy generated by renewables fluctuates depending on the natural variability of resources at any given time. The sun isn't always shining, nor is the wind always blowing, so traditional power plants must be ...
