How does a wind turbine generate electricity? — Energy
How does a wind turbine generate electricity? A wind turbine works by catching the energy in the wind, using it to turn the blades, and converting the energy to electricity through a generator in the part of the turbine called a nacelle. While some turbines are direct drive, most have a gear box that increases and controls generator speed.Web
Wind power — even without the wind
April 25, 2013. 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 generated by floating wind farms to be stored and then used, on demand, whenever it's needed.Web
Renewable Energy
Tidal energy harnesses the power of ocean tides to generate electricity. Some tidal energy projects use the moving tides to turn the blades of a turbine.
