Geothermal

Background Information

The word geothermal comes from the Greek words geo(earth) and therme(heat), so it means earth heat.Geothermal originates from Earth's fiery consolidation of dust and gas over 4 billion years ago at Earth's core-4,000 miles deep- with temperatures that may reach over 9,000 degrees Farenheit.

Advantages

Geothermal is clean because it doesn't burn fuels and conserves fossil fuels. It reduces emissions that harm the atmosphere. Geaothermal also is easy on the land because it's smaller, reliable, flexible, cheap, and helps other developing countries grow.

Disadvantages

Geothermal is high in installation costs, availability is limited, has harmful gas potential, only localized supply, the steam can stop, and visual pollution.

How Its Used

Geothermal is used to drill wells into geothermal reservoirs to bring hot water to the surface, generates electricity, soothes aching muscles in hot springs, grows flowers and veggies, pasturizes milk, dries onions and lumber, and washes wool.

Where Its Used

Geothermal is mostly found in western states but is also found in Alaska and Hawaii.

The first geothermally generated electricity in the world was produced at Larderello, Italy, in 1904. Geothermal grew worldwide to about 7,000 megawatts in 21 countries. The U.S.A. alone produced 2,700 megawatts of electricity from geothermal energy, which is equivilent to burning 60 million barrels of oil.
