Tell Me Why?

Hydro-power is the capture of the energy (by means of waterwheels or hydraulic turbines) of moving water (falling or flowing water) to generate electric power. This falling of water can be from a natural falling source or from a dam. The falling water is used to turn waterwheels or modern turbine blades which is used to power a generator to produce electricity. A water turbine, for example, captures the energy in the falling water and converts the hydraulic energy into mechanical energy at the turbine shaft. The turbine then powers an alternator which converts mechanical energy into electrical energy. The water power is used to generate electric power. This electricity produced by hydro-power is called Hydroelectricity.

Hydro-power system (hydroelectric power) is a clean source of energy systems that can neither pollute or be consumed during its operation. It eliminates the cost of fuel, making it immune to price increases for fossil fuels. The same applies to nuclear power which generates very dangerous nuclear waste. As long there is a water source (lake, river etc.) it is renewable - a renewable energy source.
