Fully renewable electricity could be competitive

(Phys.org) —A carbon price of between $50 and $100 per tonne of carbon dioxide would make coal-fired and gas-fired power less economical than renewable electricity, a UNSW study shows.

Using fluctuating wind power

Incorporating wind power into existing power grids is challenging because fluctuating wind speed and direction means turbines generate power inconsistently. Coupled with customers' varying power demand, many wind-farm managers ...

A new point of reference for offshore energy development

A new Department of Energy research facility could help bring the U.S. closer to generating power from the winds and waters along America's coasts and help alleviate a major hurdle for offshore wind and ocean power development.

Solar and wind energy may stabilise the power grid

(Phys.org)—Renewable energies such as wind, sun and biogas are set to become increasingly important in generating electricity. If increasing numbers of wind turbines and photovoltaic systems feed electrical energy into ...

Wind turbines - bigger means more environmentally friendly

(Phys.org) -- A study conducted by researchers from the ETH and Empa has come to the conclusion that large sized wind turbines produce "greener" electric power than small ones. Environmental benefits have also accrued as ...

Power generation is blowing in the wind

(PhysOrg.com) -- By looking at the stability of the atmosphere, wind farm operators could gain greater insight into the amount of power generated at any given time.

Magnetic breakthrough may have significant pull

(PhysOrg.com) -- Northeastern University researchers have designed a super-strong magnetic material that may revolutionize the production of magnets found in computers, mobile phones, electric cars and wind-powered generators.
