 Wind Energy Wind energy (or wind power) refers to the process of creating electricity using the wind, or air flows that occur naturally in the earth’s atmosphere. Modern wind turbines are used to capture kinetic energy from the wind and generate electricity. There are three main types of wind energy: 1) Utility-scale wind: Wind turbines that range in size from 100 kilowatts to several megawatts, where the electricity is delivered to the power grid and distributed to the end user by electric utilities or power system operators. 2)  Distributed or "small" wind:  Single small wind turbines below 100 kilowatts that are used to directly power a home, farm or small business and are not connected to the grid. 3) Offshore wind:  Wind turbines that are erected in large bodies of water, usually on the continental shelf. Offshore wind turbines are larger than land-based turbines and can generate more power. How wind turbines work When the wind blows past a wind turbine, its blades capt

 Hydroelectric Energy Hydroelectric energy , also called hydroelectric power or  hydroelectricity , is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity. People have used this force for millennia. Over two thousand years ago, people in Greece used flowing water to turn the wheel of their mill to ground wheat into flour. How Does Hydroelectric Energy Work? Most hydroelectric power plants have a reservoir of water, a gate or valve to control how much water flows out of the reservoir, and an outlet or place where the water ends up after flowing downward. Water gains potential energy just before it spills over the top of a dam or flows down a hill. The potential energy is converted into  kinetic energy  as water flows downhill. The water can be used to turn the blades of a  turbine  to generate electricity, which is distributed to the power plant’s customers. Types of Hydroelectric Energy Plants There are three diffe
