The efficiency of wind turbines

Wind turbines derive their energy form the kinetic energy in wind. When the wind blows the turbine revolves and the turbine is connected to a generator which generates direct current electricity. The electricity is inverted into alternating current electricity and then fed into a grid or into a place where the electricity is used. There is a limit to the energy in any given amount of wind, but there is also a limit to the maximum amount of energy that any turbine can collect and harness. Continue reading
