Wind energy is currently the most used green energy source in the United States. Typically, wind powered systems use a wind turbine, which converts kinetic energy of the wind into electrical energy. The most commonly used turbines are horizontal-axis, with two or three blades. As the blades spin, they work a generator which generates the electricity.

The turbines look similar to the large, white wind turbines that may be seen in various parts of the world. Of course, the blades aren’t nearly as big, and in order to compensate, the turbines are typically mounted on tall towers. As altitude increases, the wind system is able to produce more electricity. Homeowners should desirably own at least an acre of land, and live in an area with sufficient wind for the system to function.

Wind power systems can also work in conjunction with other types of green energy, like solar power. This allows for excess energy to be stored in case of emergency.

The cost of a wind energy system can vary wildly depending on the system a homeowner purchases, the size of the turbine, height of the tower, and a couple other costs. A system can cost between $10000 all the way up to $70000. Wind power energy systems installed between 2021 and 2032 are eligible for 30% tax credit.
