An answer to green energy could be in the air

(PhysOrg.com) -- In Mark Moore's world, long nanotubes reach into the clouds, serving at once to tether a turbine-vehicle flying at 2,000 feet, or 10,000 feet, or 30,000 feet (610, 3,050 and 9,150 meters); and also to conduct ...

Enhancing the efficiency of wind turbines

A milestone in the history of renewable energy occurred in the year 2008 when more new wind-turbine power generation capacity was added in the U.S. than new coal-fired power generation. The costs of producing power with wind ...

Storing green electricity as natural gas

Renewable electricity can be transformed into a substitute for natural gas. Until now, electricity was generated from gas. Now, a German-Austrian cooperation wants to go in the opposite direction. In the future, these researchers ...

Proposed wind power grid to make wind power more reliable

The energy needs of the entire human population could potentially be met by converting wind energy to electricity by means of wind turbines. While offshore wind power resources are abundant, wind turbines are currently unable ...

Norway plans the world's most powerful wind turbine

Norway plans to build the world's most powerful wind turbine, hoping the new technology will increase the profitability of costly offshore wind farms, partners behind the project said Friday.

China harnesses mountain wind power

In the mountains above the southwestern Chinese town of Dali, dozens of new wind turbines dot the landscape -- a symbol of the country's sky-high ambitions for clean, green energy.

Report examines limits of national power grid simulations

America's power grid today resembles the country's canal system of the 19th Century. A marvel of engineering for its time, the canal system eventually could not keep pace with the growing demands of transcontinental transportation.
