How a Small Wind Electric System Works. Wind is created by the unequal heating of Earth's surface by the sun. Wind turbines convert the kinetic energy in wind into clean electricity. When the wind spins the wind turbine's blades, a rotor captures the kinetic energy of the wind and converts it into rotary motion to drive the generator.

Tidal energy harnesses the power of ocean tides to generate electricity. Some tidal energy projects use the moving tides to turn the blades of a turbine. Other projects use small dams to continually fill reservoirs at high tide and slowly release the water (and turn turbines) at low tide. Wave energy harnesses waves from the ocean, lakes, or ...

Water-pumping windmill. A water-pumping windmill pumps water from wells, ponds, and bore wells for drinking, minor irrigation, salt farming, fish farming, etc. Available windmills are of two types, namely direct drive and gear type. The most commonly used windmill has a horizontal axis rotor of 3–5.5 m diameter, with 12–24 blades mounted on ...

People used wind energy to propel boats along the Nile River as early as 5,000 BC. By 200 BC, simple wind-powered water pumps were used in China, and windmills with woven-reed blades were grinding grain in Persia and the Middle East. New ways to use wind energy eventually spread around the world. By the 11 th century, …

How does a wind turbine generate electricity? A wind turbine works by catching the energy in the wind, using it to turn the blades, and converting the energy to electricity through a generator in the part of the turbine called a nacelle. While some turbines are direct drive, most have a gear box that increases and controls generator speed.
