Wind is caused by the uneven heating of the air by the sun, irregularities of Earth’s surface, and Earth’s rotation. Wind energy, or wind power, is the process by which the wind is used to generate mechanical power for electricity. Wind turbines convert the kinetic energy in the wind into mechanical power, which can be used for electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity. • The electricity is sent through transmission … [Read more...]
