Geothermal energy is energy emitted from the Earth's crust. Derived from magma, molten rock in the earth's crust and the natural process of radioactive decay of potassium, uranium and thorium. Magma is extremely hot found because of the enormous amount of pressure and friction in the region of the earth's subsurface.
Geothermal energy, while in massive quantity, do not fare too well when compared to the energy of the sun, which wins hands down by a factor of 20,000. Nevertheless, this form of energy that is currently tapped for use by more than 20 countries, especially Iceland, which receives about 17% of the total electricity needs from geothermal energy. The largest geothermal power plants are currently churn a few hundred megawatts of energy. Current estimates state that Iceland may have enough energy to produce 1700 megawatts of electricity to give the next 100 years.
Simply put, the process of extracting energy from the earth is very simple. The water is pumped through pipes to the source of heat, then boiled and the resulting operating a steam turbine that generates current. The water then condenses again sent through the pipes to repeat the cycle. When the tubes were used were strong and deep enough we could slide it on the mantle, what. An inexhaustible source of electricity
Currently, criticism of geothermal exploration and prevent full implementation on a large scale. Critics say that the study is too expensive and the development time is too large. Once we overcome the hurdles that we have to invest large amounts of money to the geothermal power plant with no promise that it will build a profit. Once tapped geothermal locations may not be the required amount of steam, and to make it a reliable. And in the background, environmentalists worried that the process of adjustment could bring magma to the surface of potentially harmful materials with him.
It is my many felt that his and reinforced with continuous development, it would be only a matter of time before all the critics are silenced. A geothermal fact is that since the earth Energy no pollutants would be produced. This form of energy is a very efficient method and the effort required to channel their powers are minimal once a productive website is found and completed construction. In addition, geothermal systems are not nearly as great as nuclear facilities, huge dams or electrical systems. This alone should comfort those opposed to geothermal plants because of environmental degradation. As with any alternative energy sources, it would mean using less fossil fuel dependence. The most important factor in using this as an energy source is its wealth - we are never out of it! Moreover, it is a commodity that should always be less expensive over time, since it is ubiquitous. This form of energy, in the end should be very inexpensive when research, development and implementation to close.
In a narrower sense, geothermal as an energy source differs from the likes of wind and water, because of how gained energy from the ground is slowly cools. As a result of radioactive heating geothermal energy is replenished slowly. It appears that at a depth of 50 to 60 miles below the earth's surface, there are pockets of molten rock have to temperatures which have 1200-2200 degrees Fahrenheit range. At these temperatures, we would be provided with an ominous source of geothermal energy. Unfortunately, at this time, the deepest hole extends below undertaken only 8 miles. As we become less dependent on fossil fuels, the sun will soon geothermal and nuclear energy in providing the world's industries, homes and offices with clean energy.
Geothermal energy is reliable, sustainable, environmentally friendly and above all, cost. Recent advances in technology have the size and reach of viable resources expanded, especially for heating applications. Release gases geothermal drilling deep into the earth, but when compared to fossil fuels have a minimal impact. The result, an energy source that can potentially minimize global warming, when used in place of fossil fuels. If geothermal energy can help reduce our electricity bills, questions need energy prices, interest rates and subsidies are answered....
