Wind energy is a renewable energy source that converts wind into electricity using wind turbines:
Here's how wind energy is generated:
1. Wind
Wind is created by differences in air pressure caused by solar radiation. Warmer areas have lower pressure, and colder areas have higher pressure.
2. Wind turbine
The wind's kinetic energy is collected by the turbine's blades. The blades turn due to the lift created by the wind, similar to airplane wings.
3. Generator
The blades are connected to a drive shaft that turns a generator at the top of the turbine tower. The generator converts the rotational energy from the blades into electrical energy.
The electricity generated by wind turbines can be used to power specific needs, like a streetlight or farm, or it can be added to the electric grid.
Wind power has grown rapidly in recent decades. In the United States, wind turbines generated about 10.3% of the country's utility-scale electricity in 2022. Globally, wind power is expected to increase to 30% of the world's energy generation by 2050.
