Hydro energy is the energy produced from :
Answer: B
Hydro energy is produced from water.
Hydroelectric power uses the potential energy of water stored at a height, behind a dam or in a river with a steep fall. As the water flows down through turbines, its energy turns the turbines and drives generators. Because the water cycle is driven by the sun, it is a renewable source.
Energy from sunlight directly is solar energy, and coal is a fossil fuel burned in thermal power stations, so neither is hydro energy.
