What is Wind Power?
We’re all familiar with what wind is. Caused by the uneven distribution of heat on earth, air is put into motion. As explained by the Department of Energy, “During the day, the air above the land heats up more quickly than the air over water. The warm air over the land expands and rises, and the heavier, cooler air rushes in to take its place, creating wind. At night, the winds are reversed because the air cools more rapidly over land than over
The idea behind wind power is simple – harness this natural force and use it to generate electricity. Just like we learned in school, the movement of an object produces kinetic energy. This energy rotates the blades of a wind turbine, which spin to generate electricity in an electric generator
