Small Wind Electric Systems | Department of Energy
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.
How turbines work | Impulse and reaction turbines
The more energy there is in the air, the more power a wind turbine can make. It''s just like the water. The harder it''s hitting your hand, the more energy it has, so the more energy you could catch and turn into power. A wind turbine is built very high up in the air because the wind (the air) moves much faster there.

Renewable Energy
Today, we capture the wind''s energy with wind turbines. A turbine is similar to a windmill; it has a very tall tower with two or three propeller-like blades at the top. These blades are turned by the wind. The blades turn a generator (located inside the tower), which creates electricity. Groups of wind turbines are known as wind farms.

Putting Wind to Work
Wind turbines generate electricity. Windmills were originally designed to grind (mill) grain and pump water. In both ancient and modern windmills, a drive shaft connects the rotating blades to a series of two large wheels (millstones) on the floor of the windmill. (The housing for these wheels is why windmills have wide, conical shapes while

Electricity in the U.S.
Wind turbines convert wind energy into electricity. Hydropower plants produced about 6.2% of total U.S. utility-scale electricity generation and accounted for 28.7% of electricity generation from renewable sources in 2022. 1 Hydropower plants use flowing water to spin a turbine connected to a generator.
How Does a Wind Turbine Generate Electricity?
The basic principle behind a wind turbine is fairly simple. Instead of using electricity to power a fan to make wind, wind turbines use the wind in order to make electricity. The wind turns propeller-like blades of a turbine around a rotor. This spins a generate which then generates electricity. The process of converting wind to mechanical
