The continuing extinction of fossil fuels and increasing pollution due to these non renewable sources has forced the world to focus from non renewable energy sources to the renewable sources. There is a huge variety of these renewable energy sources available for you. These sources are environment friendly as well as clean sources of energy. There are many options available with us to generate electricity in an Eco-friendly manner. These sources cover hydroelectricity production that means production of electricity by the use of water and another option is the tidal power i.e. electricity production through the dams and geo thermal which means by the use of heat from the earth. hydroelectric power produces electricity by the use of the force of running water. Usually these projects are set up near the water sources that can be a river or any else. It contains a water wheel that is turned and rotated by the river flow. Due to which a turbine is rotated, that produces required amount of electricity, but even it needs special conditions to work efficiently. The condition required is that the water must run constantly. This is thought to be a bit expensive method of producing electricity. The procedure demands huge mass of water to fall at a very high speed; thus, the turbines can rotate accordingly to generate electricity. This is safe, clean and eco-friendly. They can be set up both on large as well as small scale using the same principle, but with the variation in size of turbines. Normally it is used for large-scale production of electricity as it requires a lot of efforts for the small-scale production.
