Electricity generated from the energy of moving water.

Electricity generated from the energy of moving water.

• A. Hydropower
• B. Wind Power
• C. Geothermal Energy
• D. Biomass

Answer: (A)

Electricity generated from the energy of moving water is hydropower. It captures the kinetic energy of flowing water or the potential energy of water held at height and converts it into mechanical energy by turning a turbine. The turbine then drives a generator, which converts that mechanical energy into electrical energy. This makes hydropower a renewable source tied to the water cycle. Other energy types rely on different sources—wind power uses moving air, geothermal energy uses heat from beneath the Earth’s surface, and biomass comes from burning organic matter to produce steam and drive a turbine.
