What are the main advantages of geothermal energy for the environment ?
FAQ-Frequently asked questions about geothermal energy-CREGESwiss geothermal energy installations generate no combustion by-products or gaseous emissions (CO2, NOx) by-products. Each installation therefore contributes to a reduction in greenhouse gases. No substance brought to the surface by geothermal fluids remains there since all fluids are re-injected at depth. In a geothermal energy installation, no dangerous substance is transported or stored at the surface.

Geothermal Education Office - Power From the Earth's HeatClean. Geothermal power plants, like wind and solar power plants, do not have to burn fuels to manufacture steam to turn the turbines. Generating electricity with geothermal energy helps to conserve nonrenewable fossil fuels, and by decreasing the use of these fuels, we reduce emissions that harm our atmosphere. There is no smoky air around geothermal power plants -- in fact some are built in the middle of farm crops and forests, and share land with cattle and local wildlife.
Related QuestionsWHAT IS GEOTHERMAL ENERGY?
Geothermal Education Office - Power From the Earth's HeatOur earth's interior - like the sun - provides heat energy from nature. This heat - geothermal energy - yields warmth and power that we can use without polluting the environment. Geothermal heat originates from Earth's fiery consolidation of dust and gas over 4 billion years ago. At earth's core - 4,000 miles deep - temperatures may reach over 9,000 degrees F.
Related QuestionsHOW MUCH ELECTRICITY IS FROM GEOTHERMAL ENERGY?
Geothermal Education Office - Power From the Earth's HeatSince the first geothermally-generated electricity in the world was produced at Larderello, Italy, in 1904 the use of geothermal energy for electricity has grown worldwide to about 7,000 megawatts in twenty-one countries around the world. The United States alone produces 2700 megawatts of electricity from geothermal energy, electricity comparable to burning sixty million barrels of oil each year.
Related QuestionsWHAT PARTS OF THE WORLD HAVE GEOTHERMAL ENERGY?
Geothermal Education Office - Power From the Earth's HeatFor electricity and direct use: Geothermal reservoirs that are close enough to the surface to be reached by drilling can occur in places where geologic processes have allowed magma to rise up through the crust, near to the surface, or where it flows out as lava. The crust of the Earth is made up of huge plates, which are in constant but very slow motion relative to one another.
Related QuestionsWhat affects does the use of geothermal energy have on the environment?
REPP-CREST : GEOTHERMALUsing geothermal energy is an effective way to minimize air pollution while meeting energy needs. Current geothermal fields produce only about one-sixth of the carbon dioxide that a natural gas fueled electrical generating power plant produces and none of the nitrous oxide (NOx) or sulfur bearing (SOx) gases. [19] New state of the art geothermal binary and combined cycle plants produce virtually no air emissions. Each 1,000 MW of new geothermal power will offset 1.
Related QuestionsHOW HAVE PEOPLE USED GEOTHERMAL ENERGY IN THE PAST?
Geothermal Education Office - Power From the Earth's HeatFrom earliest times, people have used geothermal water that flowed freely from the earth's surface as hot springs. The oldest and most common use was, of course, just relaxing in the comforting warm waters. But eventually, this "magic water" was used (and still is) in other creative ways. The Romans, for example, used geothermal water to treat eye and skin disease and, at Pompeii, to heat buildings.
Related QuestionsHOW IS ELECTRICITY GENERATED USING GEOTHERMAL ENERGY?
Geothermal Education Office - Power From the Earth's HeatIn geothermal power plants steam, heat or hot water from geothermal reservoirs provides the force that spins the turbine generators and produces electricity. The used geothermal water is then returned down an injection well into the reservoir to be reheated, to maintain pressure, and to sustain the reservoir. There are three kinds of geothermal power plants. The kind we build depends on the temperatures and pressures of a reservoir.
Related QuestionsWHAT ARE SOME NON-ELECTRIC WAYS WE CAN USE GEOTHERMAL ENERGY?
Geothermal Education Office - Power From the Earth's HeatGeothermal water is used around the world, even when it is not hot enough to generate electricity. Anytime geothermal water or heat are used directly, less electricity is used. Using geothermal water 'directly' conserves energy and replaces the use of polluting energy resources with clean ones. The main non-electric ways we use geothermal energy are DIRECT USES and GEOTHERMAL HEAT PUMPS.

Green Mountain Energy Company: Frequently Asked QuestionsGeothermal energy comes from heat trapped within the earth's crust, the same kind of heat that is evident in volcanic activity and geysers. Geothermal power plants tap steam and hot water trapped underground to convert that energy into electricity.
Related QuestionsECONAR GeoSource Geothermal Heat PumpsHigh-grade geothermal energy is the heat of the earth’s pressure that turns water into stream. Old Faithful at Yellowstone National Park is an excellent example. Low-grade geothermal energy is the heat within the earth’s crust. This heat is actually stored solar energy. ECONAR taps into this low grade geothermal energy and delivers big energy savings when heating, cooling and making hot water.Related Questions
What are the benefits of using geothermal energy?
POLARIS GEOTHERMAL INC.First, it's clean. The energy can be extracted without burning a fossil fuel such as coal, gas, or oil. Geothermal fields produce only about one-sixth of the carbon dioxide that a relatively clean natural-gas-fueled power plant produces, and very little if any, of the nitrous oxide or sulfur-bearing gases. Binary plants, which are closed cycle operations, release essentially no emissions. Geothermal energy is available 24 hours a day, 365 days a year.
Related QuestionsWhy is geothermal energy a renewable resource?
POLARIS GEOTHERMAL INC.Because its source is the almost unlimited amount of heat generated by the Earth's core. Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be reinjected, making it a sustainable energy source.
