What are the three ways to get geothermal energy?

There are three types of geothermal power plants: dry steam, flash, and binary. Dry steam, the oldest geothermal technology, takes steam out of fractures in the ground and uses it to directly drive a turbine. Flash plants pull deep, high-pressure hot water into cooler, low-pressure water.

What is geothermal energy for kids?

Geothermal energy is heat that comes from inside Earth. It is an alternative energy source that can be used for cooking, bathing, and heating. It can also be converted into electricity. Geothermal energy is available anywhere on Earth’s surface.

What is the source of geothermal source of energy?

Geothermal energy is produced by the heat of Earth’s molten interior. This energy is harnessed to generate electricity when water is injected deep underground and returns as steam (or hot water, which is later converted to steam) to drive a turbine on an electric power generator.

What is geothermal energy class 10?

Geothermal energy is the heat energy from hot rock present inside the earth. The rocks at some depth below the surface of the earth are very, very hot. This heat comes from the fission of radioactive materials which are naturally present in these rocks.

What is the geothermal energy Why is it a renewable source of energy?

Why is geothermal energy a renewable resource? Answer: Because its source is the almost unlimited amount of heat generated by the Earth’s core. Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be reinjected, making it a sustainable energy source.

Where can we find geothermal energy sources in India?
