ABSTRACT
Wind turbines catch kinetic energy in the wind and transform it into other forms of energy: mechanical work in water pumps and windmills or electric power in modern wind turbines. The wind is a renewable energy source; the wind is set in motion by the differences in temperature and air pressure created by the sun’s radiation on Earth. Wind turbines produce clean energy, don’t need any fuel transport that can be hazardous to the environment, don’t create air pollution and don’t leave any hazardous waste behind.
