Geothermal Energy

By Ethan Stumbo

Is it renewable

Geothermal energy is a renewable resource. The heat from the Earth in the section we mine may become to cold or to scarce but it will reheat eventually.

Where is it found?

Geothermal heat can be found almost anywhere within the top ten foot or so layer of the Earths crust and is extracted using a geothermal heat pump system.

It is normally found at fifty to sixty degrees fahrenheit.

How do we use it?

Direct geothermal energy

We use hot springs to pump hot water directly to peoples houses to power them

Geothermal power plant

there are three types

Dry steam plants. steam is pumped directly from reservoirs into generators in the plant. The steam spins turbines, which generate electricity.

Flash steam plants. Water 300 and 700 degrees Fahrenheit is brought up through a well. Some of the water turns to steam, which runs the turbines. When the steam cools it condenses back into water and is returned to the ground.

Binary cycle plants. Warm water is passed through a heat exchanger, where its heat is transferred to a liquid that boils at a lower temperature than water. When that fluid is heated it turns to steam, which spins the turbines.

What is made from it?

It is used to generate power in homes stores and factories.

Who uses it?

Anyone who wants a greener way of making energy.

What are the cost benefits?

It is 80% cheaper than fossil fuels and green.

What is the environmental impact?

The only environmental impact is that habitats around drill sites can get damaged.

What are some advantages and disadvantages?

It is 80% cheaper than fossil fuels and greener. It is made 100% naturally.

The only disadvantage is that it damages the habitats around where its drilled.
