Geothermal power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth's surface. The steam rotates a turbine that activates a generator, which produces electricity.

Some natural sources of geothermal energy are hot springs, steam vents, underwater hydrothermal vents, and mud pots [1]. Their geothermal heat can be captured and used directly for heating, or the steam is used to generate electricity.

Conversion of Geothermal Energy into Electricity. One of the most used applications of geothermal energy is the generation of electricity. The choice of technology for the production of electricity depends on the type of geothermal deposit. Geothermal energy uses steam to drive the steam turbine.

Geothermal electricity generation Geothermal electricity generation requires water or steam at high temperatures (300° to 700°F). Geothermal power plants are generally built where geothermal reservoirs are located, within a mile or two of the earth's surface.

Electricity can be generated by drilling Wells into reservoirs. Some geothermal power plants use the steam from a reservoir to power a turbine/generator, while others use the hot water to boil a working fluid that vaporizes and then turns a turbine. Hot water near the surface of the earth can be used directly for heat.

Extremely hot rocks present below the surface of earth heat the underground water and turn it into steam. As more and more steam is formed between the rocks, it gets compressed to high pressures. This high pressure steam is brought up through pipes and is used to run the turbine of a generator to produce electricity.

To produce power from geothermal energy, wells are dug a mile deep into underground reservoirs to access the steam and hot water there, which can then be used to drive turbines connected to electricity generators. There are three types of geothermal power plants; dry steam, flash and binary.

The water runs through cracks in the rocks and is heated up. It returns to the surface as hot water and steam. The diagram shows how this works. Geothermal energy can be used to generate electricity

Geothermal energy is a renewable energy source that uses hot water and steam sourced from deep within the Earth’s surface to generate electricity.

The flow chart above illustrates the process of generating energy through a geothermal source. Overall it can be seen that electricity is obtained by the heating of water that converted into steam can produces energy.

Electricity Generation. The United States of America continues to generate the most geothermal electricity in the world: more than 3.5 gigawatts, predominantly from the western United States. That's enough to power about three and half million homes! Pictured above, the Raft River geothermal plant is located in Idaho.

The British Geological Survey describes geothermal energy as a “carbon-free, renewable, sustainable form of energy that provides a continuous, uninterrupted supply of heat that can be used to heat homes and office buildings and to generate electricity.”. Geothermal energy only produces one-sixth of the CO 2 produced by a natural gas plant ...

Geothermal power plant. Hot water and steam from deep underground can be piped up through underground wells and used to generate electricity in a power plant. Three different types of geothermal power plants exist:

Kenya was the eighth-largest geothermal electricity producer at about 5 billion kWh, but it had the largest share of its total annual electricity generation from geothermal energy at 46%. Geothermal heat pumps. Geothermal heat pumps use the constant temperatures near the surface of the earth to heat and cool buildings. Geothermal heat pumps ...

Whether geothermal energy is used to generate electricity or directly, the characteristics of geothermal deposits determine the technology to be exploited. The geothermal fluid often contains large amounts of gases such as hydrogen sulfide and various chemical solutions that can be very toxic.
