A wind turbine is a device that converts the energy of the wind into electricity. It has large blades that spin when the wind blows, which turns a generator inside the turbine. This process helps produce clean energy, reducing our reliance on fossil fuels and lowering greenhouse gas emissions. Wind turbines are often found in wind farms, where many turbines are grouped together to generate a significant amount of power. They can be located on land or offshore, taking advantage of strong winds over the ocean. By harnessing wind energy, we can create a more sustainable future for our planet.
