Energy that is produced without permanently using up the Earth's limited resources is called renewable energy. Apart from bio-mass fuels, which produce smoke and other fumes when burned, renewable energy sources are pollution free, because they harness the energy of natural phenomenon such as winds and waves. As the Earth's fossil fuel reserves are gradually used up, people will have to rely much more on renewable energy sources.
Some of the renewable energy resources are:
1.Geothermal power
2.Hydroelectric power
3.Wind power
4.Wave power
5.Solar power
6.Biomass Fuels
7.Tidal barrage
