Fossil fuels are obtained from the earth’s crust as they are the remains of the dead plants and animals. They are similar to coal and petroleum and readily available for use. These are non-renewable source of energy and cannot be replenished. Whereas solar energy is abundant in nature and can be repRead more

Bio-mass is obtained from the dead plants and animals. It is a renewable source of energy. Examples of bio-mass sources of energies are wood, gobar-gas. Hydroelectricity is obtained from the potential energy of the stored water at a certain height. Water from a certain height is made to fall on theRead more

Hydroelectricity is obtained from the potential energy of the stored water at a certain height. Water from a certain height is made to fall on the turbines of the generator resulting in electricity. Dams and reservoirs are used in hydroelectricity.
Both bio-mass and hydroelectricity are renewable sources of energies.
Wind energy is trapped using windmills. One of the limitations of the wind energy is that the windmills requires a speed more than 15 km/h to generate electricity. And the number of windmills will be more to cover a huge area.

In order to extract energy from the tides, the sun, the moon and the earth should be in a straight alignment and the tides should be very strong.
