National Science Bee Practice Test

Which term describes the energy stored in the movement of air that can be harnessed for electricity?

Geothermal energy Uranium Wind energy Chlorofluorocarbons

Correct Answer:

Wind energy

Explanation:

Wind energy describes the energy stored in moving air that can be harnessed for electricity. When air moves, it has kinetic energy, and turbines capture that energy as the blades spin, turning it into electrical energy through a generator. Geothermal energy is heat from beneath the Earth’s surface, uranium is a nuclear fuel used to produce heat in reactors, and chlorofluorocarbons are chemicals with no direct role in generating electricity. Wind energy is the term that fits the idea of using moving air to produce power.
