In the recent years, wind energy has gained immense popularity worldwide. Over the years efforts have been made to make the wind power generators more efficient and practical. For example, windmills for generating mechanical power, wind turbines to produce electricity, etc.

(ii) Tidal energy refers to the energy derived from the tides of the sea. As we know high and low tides are created in the sea are generated by the gravitational pull of the moon and the rotation of the earth. Tidal energy is the energy derived from such tides. For example, tidal barrages are used to capture the tidal energy to produce energy.
