Best answer: What is 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.

Why is geothermal energy a renewable source?

Geothermal energy is a renewable energy source because heat is continuously produced inside the earth.

What is geothermal energy short answer?

Geothermal energy is the heat that comes from the sub-surface of the earth. It is contained in the rocks and fluids beneath the earth’s crust and can be found as far down to the earth’s hot molten rock, magma. … There are three types of geothermal power plants; dry steam, flash and binary.

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 and its uses?

Geothermal energy is heat derived within the sub-surface of the earth. Water and/or steam carry the geothermal energy to the Earth’s surface. Depending on its characteristics, geothermal energy can be used for heating and cooling purposes or be harnessed to generate clean electricity.

Is geothermal energy a renewable or non renewable source of energy?

Geothermal energy is a renewable resource. The Earth has been emitting heat for about 4.5 billion years, and will continue to emit heat for billions of years into the future because of the ongoing radioactive decay in the Earth’s core.

Why geothermal energy is classed as both a renewable and nonrenewable energy source?

Geothermal energy is a renewable energy source! This is because it’s a source with almost an unlimited amount of heat generated by the Earth’s core. It is not a nonrenewable source of energy because it can be re-used without being truly depleted!

What is geothermal energy class 10th?

Geothermal energy is the thermal energy generated and stored inside the Earth’s crust. … These molten rocks formed in the Earth’s crust are pushed upward where they get trapped in certain regions called ‘hot spots’. When underground water comes in contact with the hot spot, steam is generated.

What is geothermal energy class 8 short answer?

Geothermal energy is the heat energy which is generated and stored inside the Earth’s crust. … These molten rocks formed in the crust are pushed further upward where they eventually get trapped in certain regions known generally as ‘hot spots’.

What is geothermal energy and examples?

A Geyser is an example of Geothermal energy. Hot springs, lava, and fumaroles are natural examples of geothermal energy. Geothermal power is currently more common in homes and businesses, using geothermal heat pumps to control the temperature in the building.

How does geothermal energy produce energy?

Geothermal power plants use steam to produce electricity. 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.

Why is geothermal energy important?

Geothermal energy, one of the most promising among renewable energy sources, has proven to be reliable, clean and safe, and therefore, its use for power production, and heating and cooling is increasing. It is a power source that produces electricity with minimal environmental impact [3], [4], [5].

Why is geothermal energy considered a renewable resource apex?

Because there is an infinite supply of heat from the Earth and it requires no effort to replenish, it is , it is considered self-replenishing, and therefore renewable.

How effective is geothermal energy?

With a possibility of more than 400% efficiency and nearly zero emissions, it is not surprising that geothermal energy is considered one of the most efficient, cost effective, and environmentally friendly sources of energy. Geothermal energy is an effective, inexhaustible, and renewable resource.

What is geothermal energy by Brainly?

Geothermal energy is the energy obtained from the earth(geo) from the hot rocks present inside the earth. It is produced due to the fission of radioactive materials in the earth’s core and some places inside the earth become very hot.
