Why Geothermal Power Is so Advantageous
As organic based fuels become much more scarce, scientists are pushing for the research and development of green option fuel. A variety of potential energy sources have been suggested: wind, solar, water, and nuclear to name a few. Even though they’re natural, not all are available globally 24/7. There is one more option, one that’s perpetual and discovered right 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’s inexpensive, renewable, and ecologically friendly. Despite using the sun, wind, water and nuclear energy for electrical power, there is stil one organic resource that has yet to become harnessed. One that’s inexpensive, abundant, and effective: geothermal energy.
So that you can fully understand why geothermal energy is so essential, here is a broken down explanation.
What Precisely Is Geothermal Power?
Geothermal energy (literally heat from the earth in Greek), is really a phenomena caused by the constant decay of minerals in 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 is perpetual and is discovered nearly everywhere within the world.
How Does it Work?
In order to create electrical power, the real power source used in homes and offices, turbines need 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 through 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 produced that may harness thermal power directly from magma and with water can flash produce 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 energy for about 5 cents per watt. In total; one geothermal plant accounts for about 1/4 of the entire states electricity. 1 geothermal plant accounts for the same power as approximately three nuclear plants. This is because geothermal power is run 24/7 in contrast to nuclear plants which spend time switching fuel rods and shutting off the core each night.
Abundance?
Wherever there’s earth, there is geothermal energy. Nevertheless, 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 should dig deeper to access more heat.
Environmental Effects?
The only waste created is going to be heat; not so bad! Furthermore, geothermal energy plants are smaller than most, reducing visual pollution and preventing sights like “wind vane forests”.
So there you have it. Geothermal Power offers 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.
