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

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

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.

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

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

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

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

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