1. Geothermal Energy
Geothermal energy is the harvesting of the earths natural heat that is produced by the earths core. In order to harness this heat, the use of shallow ground water and hot water and rock several miles below the earth's surface are utilized. Even further down, the heat of molten rock called magma is also used. One main use this technology is a geothermal heat pump. This technology uses shallow ground water to heat and cool homes and buildings. Almost everywhere on the earth, the top ten feet of the surface maintains a constant temperature of 50-60 F. These Heat pumps consist of shallow buried pipes near a building, heat exchangers, and ductwork running into the building. The heart removed from houses during the process can be used to heat water. .
Power plants can also be used to generate electricity from geothermal reservoirs. To utilize the earth's natural heat, deep wells, sometimes up to two miles deep have to be drilled into heat reservoirs that are pocketed throughout the planet. From these wells, steam and hot water either rise to the surface naturally or are pumped up. This heat is then used in order to turn turbans and create electricity. There are three main types of power plants that perform these operations. The first are dry steam plants, which directly use geothermal steam to turn turbines. The second, flash steam plants pull deep, high-pressure hot water into lower-pressure tanks and use the resulting flashed steam to drive turbines. The final are binary-cycle plants, which pass hot water by a secondary fluid with a much lower boiling point than water. This causes the secondary fluid to flash to steam, which in turn drives the turbines.
This method or producing electricity has many very persuasive advantages. The main advantage is that electricity is produced in an efficient, ecologically completely safe way. There are no fossil flues of any kind burned in this process, and therefore would reduce pollution by 100%.
Geothermal Energy. ... Geothermal energy is heat energy that comes from the earth. ... Geothermal energy can be divided into low grade and high grade energy. ... Geothermal energy can only be used where there is geothermal activity is nearby. Current Applications of Geothermal energy In Iceland geothermal energy has successfully been used to heat their homes. ...
One type of alternative energy that should be used is Geothermal energy. ... As of 2012, only 0.41% of the electricity generated in the United States came from Geothermal energy. ... Another advantage that comes along with using Geothermal energy is that the power stations for Geothermal energy are very small, and because of this they tend to have a small impact on the surrounding environment. ... One of the most significant reasons why we should start using Geothermal energy to create our electricity is once a geothermal power station is built, the energy is nearly free. ... Geothermal ener...
Geothermal energy represents the inner heat of the earth, produced largely by the decay of radioactive elements in the mantle and center. ... Geothermal energy is not free from environmental problems. ... Geothermal energy was first used in the era of the ancient Roman bath house, in which they bathed in hot salt springs. Even though the Romans found an easy way to use geothermal energy, and we still enjoy natural hot springs, the process of removing geothermal energy from the earth to use it efficiently is rather difficult. The only three ways to use geothermal energy...
Geothermal energy is the way of the future. ... What Geothermal Energy Can Do Geothermal energy can be used for power plants. ... Geothermal energy can be applied directly as a heat source for homes, offices, and other businesses. ... Unlike solar power or wind as an energy source, geothermal energy is always available. ... Geothermal energy sounds like the answer to all energy questions. ...
Hydroelectric power, Biomass energy, geothermal energy and solar power are all being used today in the United States. ... Of this hydroelectric accounts for 4%, biomass 3% and wind, solar, and geothermal energy accounts for the remaining .6%. ... Geothermal Energy is power obtained by using heat from the Earth's interior, usually in regions of active volcanoes. ... This country, which holds host to having the most active volcanoes in the world, has the possibility of using geothermal energy. ... In the 1940's Iceland began using geothermal energy to heat their houses and buildin...
Andi Yao "Geothermal Energy" Geothermal Energy is an enormous underused heat and power resource that is clean, reliable and homegrown. ... The earliest commercial use of geothermal energy was for swimming pools and spas. ... There are several attributes that make geothermal Energy a good source of energy. ... Geothermal energy offers an environmentally benign source of electricity. ... However there are still many flaws in using geothermal energy. ...
Older technologies can also be advanced; sources such as solar power, wind, geothermal, and hydropower. ... Geothermal energy is a huge source of energy that is clean and reliable. ... The World's largest geothermal power plant is of this type and is located in California. ... Geothermal power is not only safe and efficient; it is also cheap, at around six or seven cents per kilowatt hour. Geothermal power is not just limited to steam and hot water. ...
So the oil crisis is not entirely bad news, the U.S. still has time to implement alternative energy sources such as nuclear energy, hydroelectric energy, solar power, wind power, and geothermal energy, as well as alternative fuels which may be used in existing power plants. ... Geothermal energy must also be explored. Geothermal energy uses the earths core temperature of 700 degrees Fahrenheit to create steam, then convert it into heat or electricity. Geothermal energy has much potential because as long as the sun remains burning the earth is being heated. ... Geothermal energy should be a mor...
