The heat from the earth's own molten core can be converted into electricity. This core consists primarily of extremely high temperature liquid rock known as magma. This "geothermal" heat circulates within the rock or is transferred to underground reservoirs of water, which also circulate under the earth's crust. Because of the near limitless ability of the earth to produce magma, and the continuous transfer of heat between subsurface rock and water, geothermal energy is considered a renewable resource.
Geothermal resources have been harnessed as an energy source since the dawn of civilization, when natural hot springs were first used for cooking and bathing. The geothermal resources tapped to generate electricity are far more intense than those used for space heating and can reside as deep as 10,000 feet below the earth's surface. Capital costs for the construction of geothermal power plants are much higher than for large coal-fired plants or new natural gas turbine technologies. But geothermal plants have reasonable operation and maintenance costs and no fuel costs. Though more expensive than wind power in most cases, new geothermal electricity generation facilities are increasingly competitive with fossil options.Geothermal plants can operate around-the-clock, which increases their value from a reliability point-of-view, unlike some intermittent renewable fuels such as solar and wind.
Geothermal electricity generation technologies consist of either "flash" technology or "binary" technology. With flash technology, water from 300 to 700 degrees Fahrenheit, but still in liquid form, is piped from its highly pressurized underground reservoir into a geothermal facility. Once this super-heated water is released, it flashes into steam that then drives a conventional turbine generator. With binary technology, underground reservoir waters of lower temperatures are used for flashing. Heat from geothermal water is transferred to a second (binary) liquid, which flashes into vapor upon heating, and that vapor is used to drive turbines. (With dry steam technologies - a much rarer fuel source but the one used in the world's largest geothermal power plant at The Geysers in northern California -- highly pressurized geothermal vapor is used directly to drive a turbine.)

How can geothermal energy help us?
to make electricity
Can geothermal energy make electricity only during the even hours?
No, geothermal can use the heat of the earth day and night.
Give one disadvantage to converting from fossil fuels to geothermal energy?
Converting one form of energy to other always lost some energy in the process. The use of Geothermal energy is making electricity, fossil fuel can make electricity through generator. Adding unnecessary step from fossil fuel -> geothermal -> electricity is nothing more than additional loss in energy transformation process.
Can some volcanoes make geothermal energy?
yes geothermal energy is heat coming from earth's core
How is geothermal energy harnessed for energy?
There are two ways of using geothermal energy.1: There is domestic geothermal, where it is used locally to apply heat to your house or water heater.This is done by pumping water underground through pipes. The deeper underground the water is, the warmer the water will get by the use of the magma heating the earth underground. This can only be done in some locations, and is mainly used locally. So it does not make electricity, just uses the heat from underground.2: There are the big geothermal corporations, where they send water through pipes deep underground, where the water is heated by the magma. This causes the water to change phase, and become steam. The steam is then pressurized, and then put through turbines to make electricity.
Do geothermal make electricity only during the evening hours?
Geothermal energy-can make electricity all day or all night.
How can geothermal energy help us?
to make electricity
Can geothermal energy be used to make electricity?
Yes! :)
To produce or make electricity ___ it?
To produce or make electricity is to generate it. Some of the common ways of generating electricity include using wind power, geothermal energy and burning fossil fuels among others.
Can geothermal energy make electricity only during the even hours?
No, geothermal can use the heat of the earth day and night.
How is geothermal energy captured in Iceland?
Iceland is one of the most effective country in capturing geothermal energy and using i to make electricity. when water seeps into the cracks of the fissures, it is superheated by magma. the water turns into steam and escapes like a geyser and the steam rotates turbine blades creating electricity.
What produce or makes electricity is to it?
generate
What must be done to make geothermal energy transportable?
Geothermal energy is extracted form the Earth at a physical location on the Earth. To transport the energy it must be converted to electricity and sent dowm wires.
Give one disadvantage to converting from fossil fuels to geothermal energy?
Converting one form of energy to other always lost some energy in the process. The use of Geothermal energy is making electricity, fossil fuel can make electricity through generator. Adding unnecessary step from fossil fuel -> geothermal -> electricity is nothing more than additional loss in energy transformation process.
What is the geothermal energy definition?
heat under the ground used to heat water and make steam to turn generator turbines and make electricity.
What SC make electricity using electricity using energy from the sun?
Solar Cells
How can geothermal energy be converted to electricty?
The earths heat, heats up a water pipe which evaporates the water which turns a turbine that make electricity.
