What five-syllable term describes power produced when falling water turns turbines connected to electric generators?

• A. Tidal
• B. Solar
• C. Hydroelectric
• D. Geothermal

Answer: (C)

This involves converting the energy of falling or moving water into electricity by using that water to spin turbines attached to generators. The five-syllable name for this process is hydroelectric. Hydroelectric power harnesses the gravitational energy of water as it falls or flows to drive turbines, which in turn operate electric generators to produce electrical power. This method is distinct from tidal energy (ocean tides), solar energy (sunlight), or geothermal energy (Earth’s internal heat), which rely on different natural sources.
