Which energy resource uses moving air to generate electricity?

• A. Solar Energy
• B. Geothermal Energy
• C. Hydro Energy
• D. Wind Energy

Answer: (D)

Moving air contains kinetic energy that can be captured to generate electricity. Wind energy does this by using turbine blades that are turned by the wind; the rotating blades drive a generator, which converts the mechanical energy into electrical energy. This distinguishes it from the other resources: solar energy uses sunlight, geothermal taps heat from inside the Earth, and hydro relies on flowing water to turn turbines. The amount of electricity depends on wind speed and turbine design, but the essential idea is that moving air powers the generation.
