What does it mean when we say that geothermal energy is sustainable?

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 not sustainable?

There is an abundance of greenhouse gases below the surface of the earth. When geothermal energy is used, some of these gases escape towards the surface and into the atmosphere. These emissions tend to be higher near geothermal power plants.

What does it mean when we say that geothermal energy is sustainable quizlet?

Sustainable. The only way to keep geothermal energy is to return the heated water back to the ground. Why is Geothermal Energy renewable? Because the heat is continuously produced inside the Earth. Renewable Resources.

What are the 3 main uses of geothermal energy?

Geothermal energy can heat, cool, and generate electricity: Geothermal energy can be used in different ways depending on the resource and technology chosen—heating and cooling buildings through geothermal heat pumps, generating electricity through geothermal power plants, and heating structures through direct-use …

Is geothermal energy bad for the environment?

Geothermal explained Geothermal energy and the environment

Direct use applications and geothermal heat pumps have almost no negative effects on the environment. In fact, they can have a positive effect by reducing the use of energy sources that may have negative effects on the environment.

What are the two uses of geothermal energy?

People around the world use geothermal energy to heat their homes and to produce electricity by digging deep wells and pumping the heated underground water or steam to the surface. Or, we can make use of the stable temperatures near the surface of the earth to heat and cool buildings.
