The wind is air in motion, the uneven heating of the earth's surface and its atmosphere, combined with the earth's rotation, causes winds to blow.
Wind turbines and wind farms can be 60 stories tall and have 70 meters long blades, heigh altitudet=stronger, and more constant winds. Blades spin, turn an electric generator=produces electricity. can operate at land and at sea, offshore winds are better because of wind generally is much stronger and steadier over coastal waters than over land, and it avoids upset about visibility, noise and land purchase
