Generating eco-friendly power with metal rotor blades

Wind turbines deliver environmentally friendly electricity. Yet the fiber-reinforced plastics often used in very large rotor blades are almost impossible to recycle. Not so with steel blades: since these are composed of steel, ...

Researchers build a tougher, lighter wind turbine blade

Efforts to build larger wind turbines able to capture more energy from the air are stymied by the weight of blades. A Case Western Reserve University researcher has built a prototype blade that is substantially lighter and ...

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, allowing the electricity ...

Homespun power: Energy solution blows in wind with turbine

Last June, Frank Towns put up a wind turbine behind his home to generate electricity. Turns out it's generating interest, too. People driving by often stop to ask about it, and Towns is happy to share information about his ...

The way to more efficient, quieter wind turbines

A European research project aims to reduce the cost of wind energy generation by introducing technical improvements to turbines, which will have to be much quieter in the future than is the case today

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 ...
