Wind speed largely determines the amount of electricity generated by a turbine. Higher wind speeds generate more power because stronger winds allow the blades to rotate faster. . Alternative energies include 1) renewable power sources (such as solar, tidal, wind, biofuel, hydroelectric, and geothermal) and 2) nonrenewable nuclear power (considered alternative but not renewable because it relies on uranium, a finite resource not easily replenished). . The blades are connected to a drive shaft that turns an electric generator, which produces (generates) electricity. Diagram of wind turbine components Source: National Renewable Energy Laboratory, U. Department of Energy (public domain) Wind electricity generation has grown significantly in the. . Wind power or wind energy is a form of renewable energy that harnesses the power of the wind to generate electricity. Image Credit: Vladimka production/Shutterstock. com What is Wind Energy? Uneven heating of the Earth's surface from the sun, coupled with the rotation and. .
