Wind Energy 101 |
|
Wind is actually created by sunlight shining on the earth. It occurs because the light does not reach the planet evenly (such as part of the planet being dark at night). This causes differences between warmer air and cooler air and forms wind. Shorelines and the tops of mountains are two good areas to find this resource.

Applications
Wind is kinetic energy that can be used to do work. Humans can collect wind power by using wind turbines. The turbines have blades that spin and convert the wind into electrical power.

Environmental
Wind turbines, like all electricity sources, can have both positive and negative impacts on the environment. On the positive side, wind turbines emit no pollution, generate no waste, require no mining for fuel, and use negligible amounts of water. They have a small footprint and the land around them can still be used for farming or forests. On the negative side, turbines and their access roads can fragment habitat. Unless carefully constructed and maintained, the roads can lead to erosion. The turbines must be properly sited to avoid avian migratory paths and bats. Turbines are also sometimes noted for producing sound and causing a shadow flicker. Some people enjoy seeing wind turbines, viewing them as kinetic sculpture and some find them aesthetically unpleasing.

Economic
Wind energy generates jobs, increases the local tax base, and provides income for landowners. Initial costs are very high, but once it is completed, the production of energy can begin recouping those costs. Because it uses no fuel, wind turbines are not subject to fuel price spikes. Wind is renewable, so we will never run out!

Wind has been used by humans for centuries. It allowed people to sail the oceans and explore the world. We used windmills to grind grain. In the late 1800s, millions of windmills could be found in the United States pumping water. Commercial wind farms have developed over the past fifty years and can now produce large amounts of power.
