Can Geothermal Energy be considered as a renewable energy resource ?
FAQ-Frequently asked questions about geothermal energy-CREGEOn a global scale, geothermal energy is the largest energy resource. Apart from the permanent heat flux that flows to the earth’s crust, groundwater circulation continues to bring heat to the earth’s surface. The sustainable management of a geothermal reservoir, notably in reinjected fluids after cooling permits exploitation to continue for many years. The earth’s heat is unlimited on the human scale and will be available for a long time for future generations.
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.
Related QuestionsWhat types of geothermal are considered renewable and why?
REPP-CREST : GEOTHERMALAll types of geothermal energy are renewable as long as the rate of heat extraction from the earth does not exceed the rate at which the thermal reservoir it depends upon is recharged by the earthâs heat. For electricity generation, it may take several hundred years for a geothermal reservoir to recharge after it has been fully depleted. District heating systems may take 100-200 years to recharge, and for geothermal heat pumps, reservoir recovery may take 30 years or so.
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 QuestionsWhat is renewable energy?
Bioenergy and Biomass Frequently Asked QuestionsRenewable energy is any energy source that can be either replenished continuously or within a moderate timeframe, as a result of natural energy flows. The so-called "renewables" include solar energy (heat and electricity), bioenergy, wind power, hydropower, and geothermal power.
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 is clean, renewable energy?
ETF FAQsClean, renewable energy refers to electricity or heat produced from clean, renewable sources of power such as the sun, wind, water, and organic waste. Nuclear power, though it does not emit greenhouse gases, is not considered clean and renewable because of the safety concerns, radiation pollution and waste storage problems, as well as the fact that nuclear power does not replenish itself.
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 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 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 QuestionsIs biomass really a renewable source of energy?
Bioenergy and Biomass Frequently Asked QuestionsYes. If biomass is cultivated and harvested in a way that allows regrowth without depleting nutrient and water resources, it is a renewable resource that can be used to generate energy on demand, with little net additional contributions to global "greenhouse gas" emissions. Burning biomass efficiently results in little or no net emission of carbon dioxide to the atmosphere, since the bioenergy crop plants actually took up an equal amount of carbon dioxide from the air when they grew.
Related QuestionsWhy don't we use renewable energy all the time?
Do Something | informationThere are two main reasons. First of all, unlike natural gas and coal, we can't store up wind and sunshine to use whenever we need to make more electricity. If the wind doesn't blow or the sun hides behind clouds, there wouldn't be enough power for everyone. Another reason we use fossil fuels like coal and natural gas is because they're cheaper. It costs more money to make electricity from wind, and most people aren't willing to pay more on their monthly utility bills.

Solar Energy Water Heating SolutionsIt is observed that the consumption of conventional energy sources has caused more environmental damage than any other human activity. Electricity generated from fossil fuels such as coal and crude oil has led to high concentrations of harmful gases in the atmosphere. This has in turn lead to many problems such as global warming. The energy sources such as the Sun, Wind, Geothermal, water, bio-mass etc can never be exhausted and therefore are labelled 'renewable'.Related Questions
