2. What is it?
Geothermal energy is clean and sustainable heat from the Earth heat from the Earth

3. Geothermal energy come from Earth's the core
Where does it come from?
Geothermal energy come from Earth's the core

4. Efficiency And Cost
High efficiency geothermal systems are on average 48% more efficient than gas surfaces, 75% more efficient than oil furnaces, and 43% morning efficient when in the cooling mode
A power plant would probably probably require about $0.05 per kWh. But more may be required during peak demand periods.

6. Equipment
Usually extracted from areas along plate boundaries of areas marked by thin crust
Heated fluid from a geothermal resource is tapped by drilling wells as deep as 9,100 meters and is extracted by natural artesian flow
water and steam are the pumped to the power plant to make electricity or through insulated pipelines for heating and cooling applications

8. Usage
Today geothermal energy only provides two-tenths of 1% of all the energy consumed in the US
Geothermal energy is used for about 3% of the world's energy but this number changes consistently
Geothermal energy is used in many countries

10. Pros It's clean It isn't burned/ No gasses It's always available
It's home grown, reducing our dependence on foreign oil

11. Cons
It's not a widespread source of energy -This makes equipment, staff, infrastructure and training for installation scarce
High installation cost
Due to drop in temperature over time they have run out of steam
Closed regional niche

12. Environmental Problems
Some geothermal plants produce some solid materials, or sludge that require disposal
