Geothermal energy is a superior source of energy because it is constantly being produced. Radioactive decay of nuclei with long half lives that were imbedded in the Earth’s interior during its genesis accounts for seventy percent of the globe’s internal energy. The remainder of this energy is derived from either the residual heat left over form the Earth’s formation, gravitational forces, or meteorite impacts.
Geothermal energy is available anywhere on the planet. On average the Earth emits one sixteenth of a watt per meter squared, however this number can dramatically increase in regions near volcanoes, hot springs and fumaroles. Therefore, the uniqueness of each location around the world causes the Earth’s internal heat to be stored underground in many different natural structures. In some areas, the globe’s heat is stored in the rocks that form the Earth. There is a normal temperature increase, called the Normal Geothermal Gradient, of 30 degrees Celsius for every kilometer dug below the Earth’s surface. However, the precise amount of temperature increase that occurs as one’s depth increases is not a constant over the entire surface, it depends on the rock’s temperature. Therefore, in hotter sections of the planet there is Hot Dry Rock which produces an increase in temperature of forty degrees for every kilometer dug below the surface. In addition, a reserve of geothermal heat even hotter than the solid rock type is molten magma, which is melted rock.
Also, some regions of the planet house underground aquifers that use water to store large quantities of heat. Some areas contain vast hot water pools deep below the surface called Hot Water Reservoirs. In other places the conditions are r...

...ability it will surely be developed much more extensively in the near future. This source of energy will also be able to be used for a long time into the future because geothermal energy’s sources will continue to replace the energy used. In addition, it is estimated that the Earth can produce 600,000 exajoules of energy over five million years. This rate is believed to be enough energy to fulfill human energy requirements for the rest of the biosphere.

- Geothermal Energy In today's world, we are stuck in a constant debate about efficient energy usage and production. Many have gone to alternative fuel sources do to the rising cost of fossil fuels and the environmental damage caused by the burning of fossil fuels. One option that goes largely unexplored is geothermal energy. Geothermal energy is not only a much more environmentally-friendly power source than fossil fuels, but the cost of installation is not significantly more expensive than the installation of a new “High Efficiency” conventional heating system....

- I. Culture of Iceland - II. History of Geothermal Technology Culture of Iceland Iceland, the northernmost country in Europe, is a Nordic island in the Atlantic Ocean that borders the Arctic Circle. It is one of the most geologically active places in the world, and is home to numerous volcanoes, geysers, and hot springs. Iceland has a total land area of 39,770 square miles with Reykjavik as their capital, and 2,796 square miles of water area. Their total population consists of about 317,593 people.... [tags: Energy ]

- Throughout the years electricity has become a source of energy that cannot seem to be replaced; however there are many different alternatives to this source of energy. One specific alternative is geothermal energy, which might be just as effective as electricity, but much less harmful to the environment. Electricity, although very helpful, produces fuels that might be harming not only our world, but our human society. To power electricity we must use fossil fuels such as coal, oil, and natural gas.... [tags: electricity, carbon dioxide, envrionment, fuel]

- Geothermal energy is the harvesting of heat energy stored in the inner depth of the Earth’s crust . This internal heat comes from two primary sources: radioactive decay of elements and primordial heat resulting from the initial formation of the Earth . The earth’s outer layer acts as an insulator to the heat, which is why geothermal energy involves digging deep into the soil and pumping the heat from those hotter zones. Heat resources are not evenly distributed under the Earth’s surface. The highest quality superficial geothermal resources are mainly located in regions with high tectonic activity, such as the Pacific ‘Ring of Fire’ .... [tags: earth's crust, internal heat]

- Geothermal Energy The human population is currently using up its fossil fuel supplies at staggering rates. Before long we will be forced to turn somewhere else for energy. There are many possibilities such as hydroelectric energy, nuclear energy, wind energy, solar energy and geothermal energy to name a few. Each one of these choices has its pros and cons. Hydroelectric power tends to upset the ecosystems in rivers and lakes. It affects the fish and wild life population. Nuclear energy is a very controversial subject....

GEOTHERMAL ENERGY IS EARTH'S INTERIOR HEAT MADE AVAILABLE BY EXTRACTING IT FROM HOT ROCKS AND WATER. HOW IS IT CREATED. GEOTHERMAL ENERGY COMES FROM DEEP WITHIN THE EARTH'S CORE. IN THE UPPER MANTEL OF THE CRUST IS WHERE THE HEAT IS PRODUCED MOSTLY BY THE DECAY OF RADIOACTIVE ELEMENTS. THROUGH DIFFUSION THE GEO THERMAL ENERGY IS MOVED TO THE SURFACE OF THE EARTH....

- Geothermal Energy: The Answer to the Energy Problem. Abstract: The global community is currently searching for new sources of energy that are not detrimental to the environment, that are cost effective, and that will be able to provide for the current and future demand for energy. Geothermal energy is one of the promising alternatives to fossil fuels because it releases no toxic or greenhouse gas emissions, its current cost is decreasing yearly, and it is a continuous source of energy. It is a clean and efficient energy source that has the capabilities to provide for a majority of the power used in the residential, commercial, industrial, and electric power sectors....

- GEOTHERMAL ENERGY Geothermal energy is one of the oldest sources of energy. It is simply using and reusing (reusable energy) heat from the inside of the earth. Most of the geothermal energy comes from magma, molten or partially molten rock. Which is why most geothermal resources come from regions where there are active volcanoes. Hot springs, geysers, pools of boiling mud, and fumaroles are the most easily exploited sources. The ancient Romans used hot springs to heat baths and homes, and similar uses are still found in Iceland, Turkey, and Japan.... [tags: essays research papers]
