wind energy

Wind farms are groups of wind turbines that are grouped together so that they can get more energy. People are now building wind turbines in shallow water because in water there is more wind, the more wind the more energy.

A weather vane shows wind direction. An anomometer is a instrument that measures wind speed. Wind turbines are machines that change wind energy to electric energy.

Wind is air in motion. In eygpt people used the wind to power their boats in stead of motors. People also used them to grind corn.
