Hydroelectric energy is the generation of electricity by means of running or falling water. The running or falling water will drive a mechanical device a waterwheel or a turbine which in turn will drive an electrical generator to produce electricity.
In countries where you have those natural resources they build Hydroelectric Power plants to produce electricity. If you live in an area where there is a continuing flow of streaming or falling water, you can also build your mini plant making use of the water force.
This form of alternative energy produce no waste is self replenish and is considered clean energy. The energy can also be used to drive mechanical instruments like water pumps, grinding machines and cutting lumber.
Micro hydroelectric plant
Small Hydroelectric
No rainfall can influence the production of electricity.
For large hydroelectric plants a dam is made to make a reservoir of water, the stream of water is then controlled to the turbines. The turbine drives a generator. Large scale hydro has his impact on ecology of the river upstream from the dam and blocks the natural migration of fish up and down the river.
