Which resource is used in hydroelectric power generation?

Answer and explanation

Correct answer: Flowing or falling water

Hydroelectricity is produced by converting the energy of water into electrical energy. Water stored at a height has potential energy, and water moving through a channel has kinetic energy. When the water flows or falls through turbines, it rotates them; the generator then converts this mechanical motion into electricity. Thus, option A is correct because flowing or falling water is the direct energy resource used in hydropower. Dry sand and sea salt do not drive turbines, while coal ash is a residue rather than the water resource used in this process. Hydropower is generally classified as a renewable energy source when water cycles are maintained.
