Question

what is tidal and geothermal energy?

Answer 1

TIDAL ENERGY:- Oceanic tides can be used to generate electricity. During high tide water flows into the inlet and gets trapped when the gate is closed. After the tide falls outside the flood gate, the water retained by the floodgate flows back to the sea via a pipe that carries it through a powers generating turbine.

In India, the gulf of kuchchh, provides ideal conditions for utilising tidal energy.

GEO THERMAL ENERGY:- It refers to the heat and electricity both produced by using the heat from the interior of the earth. It exists because, the earth grows progressively hotter with increasing depth. Groundwater in such areas absorbs heat from the rocks and becomes hot.

In india, there are several hundred hot springs , which could be used to generate electricity.

Answer 2

Geothermal energy : It the is heat energy generated and stored in the Earth .It is extracted for heating and electricity generation. Geothermal power plant uses steam to run turbines for producing electricity.

Tidal energy : It  is the energy obtained from changing sea levels.The energy obtained from tides is converted  into electricity .Artificial tidal barrages are constructed to capture the tide. Turbines in the barrier generate electricity as the tide enter into the reservoir.
