Generating electricity
Water Energy:
Hydropower is the energy generated from flowing water. The gravitational energy from the water is released as it falls. The flow can be in terms of melting snow or streams and rivers.The energy from the water is harnessed by creating dams on the rivers.
The energy is generated from the water stored in reservoir at the dams. The water is released with force to generate the energy which can be used to generate electricity. This is a renewable source of energy as the source is natural and free once the dam is constructed.
Biomass energy:
Energy generated from natural wastes is called as biomass energy. The sources can be:
Scrap lumber
Forest debris
Certain crops
Manure
