Which of the following is an example of non-conventional source of energy?
Non- conventional sources of energy are those which have been developed in the recent past as an alternative to conventional sources of energy. These include solar energy, wind energy, tidal energy, geothermal energy, nuclear energy and biogas. They are renewable and therefore, inexhaustible, non-polluting, less expensive and easy to maintain.
Solar energy: Energy from sun is called solar energy and it is the most abundant source of energy.
Geo-thermal energy: It is the heat energy contained in the rock and fluid that fills the fractures and pores within the rock in the earth's crust. It is clean and sustainable.
Tidal energy: Energy generated from tides is called tidal energy. Tidal energy can be harnessed by building dams at narrow openings of the sea. The Gulf of Kuch is best suited for tidal energy.
