Geothermal Energy
By Ethan Stumbo
Is it renewable
Where is it found?
It is normally found at fifty to sixty degrees fahrenheit.
How do we use it?
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?
Who uses it?
What are the cost benefits?
What is the environmental impact?
What are some advantages and disadvantages?
The only disadvantage is that it damages the habitats around where its drilled.
