WHAT ARE SOME OF THE ADVANTAGES OF USING GEOTHERMAL ENERGY TO GENERATE ELECTRICITY?
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 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 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 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.

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 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 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.
Related QuestionsWhat are the environmental impacts of using geothermal energy?
POLARIS GEOTHERMAL INC.Emissions are low. Only excess steam is emitted by geothermal flash plants. No air emissions or liquids are discharged by binary geothermal plants, which are projected to become the dominant technology in the near future. Salts and dissolved minerals contained in geothermal fluids are usually reinjected with excess water back into the reservoir at a depth well below groundwater aquifers. This recycles the geothermal water and replenishes the reservoir.
Related QuestionsHow can you generate electricity aboard your boat?
Draft rec.boats.cruising FAQThe most straightforward way is the alternator hooked up to your engine. You may find that you'll want to increase its capacity significantly, especially if you want some form of refrigeration (see below). Wind power can keep your batteries charged, and can have high output if you're in a consistently windy region. Unfortunately, high winds can damage or destroy your wind generating equipment, and by all accounts it makes a terrible racket.
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 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.

Can we generate our own electricity?
Boiler & Steam Systems, LLC.Yes! You can generate your own electricity. It strictly a question of economics. Your most profitable opportunity is to displace natural gas/fuel oil used to generate steam. If after meeting the plant's thermal load, you still have a surplus of wood, you can generate additional steam and generate electricity for your plant use or to sell back to the utility or a broker.
Related QuestionsHow does the BioMax? generate electricity?
Frequently Asked QuestionsThe heart of the BioMax? is a downdraft gasifier that converts biomass to a low BTU (120 ? 160 BTU/cubic foot) producer gas, a mixture of fuel gases such as hydrogen, carbon monoxide and methane. Producer gas is converted to electricity as follows: Stirling engine: gas is combusted in a radiant burner that heats the head and transfers heat to an internal working fluid for conversion to electricity via a linear alternator.

Related QuestionsHow do solar cells generate electricity?
Energiass.com - Specialising in Solar Power in SpainPhotovoltaics or PV for short can be thought of as a direct current (DC) generator powered by the sun. When light photons of sufficient energy strike a solar cell, they knock electrons free in the silicon crystal structure forcing them through an external circuit (battery or direct DC load), and then returning them to the other side of the solar cell to start the process all over again. The voltage output from a single crystalline solar cell is about 0.
