Wind Energy
There's nothing like the feeling of a cool breeze on a hot summer day. The wind takes the heat away from your body, making you more comfortable. Wind can be used to produce other comforts, also.
Wind is caused by the uneven heating of the Earth's surface by the sun. Warm air rises. Cooler air rushes in to fill up the space. This causes wind. Wind energy is an indirect form of solar energy. It has been used for many years to power sailboats. It also powers windmills that pump water from the ground.
Wind can also power a wind turbine. A wind turbine is a tall windmill. It has large blades that look like an airplane propeller. A wind turbine is built high on a tower. This helps it capture winds that blow freely and are not blocked by trees and buildings.
