Wind power generation capacity in India has significantly increased in the last few years . The installed capacity of wind energy in India is about 8000MV.

Answer is C.

The heat from the earth's core continuously flows outward. It transfers (conducts) to the surrounding layer of rock, the mantle. When temperatures and pressures become high enough, some mantle rock melts, becoming magma. Then, because it is lighter (less dense) than the surrounding rock, the magma rises, moving slowly up toward the earth's crust, carrying the heat from below.
Sometimes the hot magma reaches all the way to the surface, where we know it as lava. But most often the magma remains below earth's crust, heating nearby rock and water (rainwater that has seeped deep into the earth) - sometimes as hot as 700 degrees F. Some of this hot geothermal water travels back up through faults and cracks and reaches the earth's surface as hot springs or geysers, but most of it stays deep underground, trapped in cracks and porous rock. This natural collection of hot water is called a geothermal reservoir.
Hence, the super-heated steam is raised in geothermal plants by the heat of magma or lava.

The steam comes from reservoirs of hot water found a few miles or more below the earth's surface. The steam rotates a turbine that activates a generator, which produces electricity Hence Geothermal energy can be used to produce electricity.

Geothermal power plants are actually known for their ability to operate continuously (base load power), unlike solar or wind, making the claim that they cannot operate round the clock false.

Renewable energy is the energy that is generated from the natural resources that can be replenished easily. Biogas is a renewable source of the energy from the given options.

Coal is a fossil fuel formed over millions of years and cannot be replenished on a human timescale, making it a non-renewable energy source.

Wood is considered a renewable energy source because it can be replenished by planting new trees within a relatively short period.

Gobar gas, vegetable refuse, and plants are all forms of biomass (renewable). Crude oil is a fossil fuel (non-renewable).

Lignite, natural gas, and coal are all fossil fuels (non-renewable). The sun is a renewable source of energy.

Thermal power plants generate electricity by heating water to produce steam, which then drives a turbine. Evaporation is central to this process.
