Why Geothermal Power Is so Advantageous
Wednesday, August 25th, 2010As organic based fuels become more scarce, scientists are pushing for the research and development of green option fuel. A plethora of potential energy sources have been suggested: wind, solar, water, and nuclear to name a few. Although they are organic, not all are available globally 24/7. There is one more choice, one that’s perpetual and discovered directly under our feet: geothermal energy.
The effects of coal and petroleum have left a sour taste in humanities mouth, which now seeks to discover power that is cheap, renewable, and ecologically friendly. Despite utilizing the sun, wind, water and nuclear power for electrical power, there’s stil one organic resource that has yet to become harnessed. 1 that’s inexpensive, abundant, and efficient: geothermal power.
So that you can fully understand why geothermal energy is so essential, here is a broken down explanation.
What Precisely Is Geothermal Energy?
Geothermal power (literally heat from the earth in Greek), is really a phenomena caused by the constant decay of minerals within the earth, absorption of the sun’s rays, and the radiating heat from the Earth’s core, with a temperature of about 9,000 degrees Fahrenheit. Simply because of this, it’s perpetual and is discovered nearly everywhere within the world.
How Does it Work?
In order to create electricity, the real energy source used in homes and offices, turbines require to become spun at energy plants which charge a generator. Water and wind directly charge the generator while sun and nuclear energy indirectly turn them via steam. With geothermal power, heat extracted from rocks and hot springs radiates via turbines with steam. Normally, most geothermal plants harness power via heated water. However, new technology is being created that can harness thermal energy directly from magma and with water can flash create steam to spin turbines.
Efficiency?
According to the United States’ University of Florida, Hawaii, the island state west of California, has 1 geothermal plant which produces about 25 megawatts of power for about 5 cents per watt. In total; 1 geothermal plant accounts for about 1/4 of the entire states electrical power. 1 geothermal plant accounts for the same energy as around three nuclear plants. This is because geothermal energy is run 24/7 unlike nuclear plants which spend time switching fuel rods and shutting off the core each night.
Abundance?
Wherever there’s earth, there is geothermal energy. However, land near tectonic plates, where volcanos, earthquakes, and geysers are discovered, are the easiest places to extract heat. The only thing this means is thermal plants not in these areas must dig deeper to access more heat.
Environmental Effects?
The only waste created is going to be heat; not so bad! Additionally, geothermal power plants are smaller than most, reducing visual pollution and preventing sights like “wind vane forests”.
So there you have it. Geothermal Power provides promising gains for humanity. With the efficiency of nuclear power without the waste or visual pollution, it provides the greatest gains of any from the option fuels.
