Top best answers to the question «How can electricity be generated by wind»
- Wind turbines use blades to collect the wind’s kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator, which produces (generates) electricity.

wind turbines can be placed, and the spinning of the propeller turns some magnetic thing against a coil, producing electricity.
Wind power requires the kinetic energy of moving air to be converted into mechanical and then electrical energy. Thus the main engineering challenges for the wind energy industry are the design of cost-effective wind turbines and the design of power plants capable to efficiently carry out the conversion.
When the electricity prices rise -- or when winds die -- energy can be withdrawn from the wheels and sold to the grid at a premium rate. "It will signal a dramatic shift to a cleaner, more ...
