Land-Based Wind Power
From sailing ships to using windmills for pumping water and grinding grain, humans have been harnessing the power of wind for thousands of years. Today’s modern wind turbines are used to generate clean, fuel-free electricity, and are a rapidly growing source of electricity across the U.S. and the world.
Grid-scale wind turbines work by using wind to turn propeller-like blades around a rotor. The rotor is connected to a main shaft, which spins a generator to create electricity. Grid-scale wind turbines are mounted on a tower 100 feet or more above ground.
