As organic based fuels turn out to be much more scarce, scientists are pushing for the research and development of green alternative fuel. A plethora of potential energy sources have been suggested: wind, solar, water, and nuclear to name a few. Although they’re natural, not all are obtainable globally 24/7. There’s another option, one that is perpetual and discovered right under our feet: geothermal power.
The effects of coal and petroleum have left a sour taste in humanities mouth, which now seeks to find energy that’s cheap, renewable, and ecologically friendly. Despite utilizing the sun, wind, water and nuclear power for electrical power, there is stil one natural resource that has yet to become harnessed. One that is inexpensive, abundant, and effective: geothermal power.
So that you can fully comprehend why geothermal energy is so essential, here is really a broken down explanation.
What Precisely Is Geothermal Energy?
Geothermal energy (literally heat from the earth in Greek), is really a phenomena caused by the constant decay of minerals in the earth, absorption from the sun’s rays, and the radiating heat from the Earth’s core, with a temperature of about 9,000 degrees Fahrenheit. Because of this, it is perpetual and is found nearly everywhere in the world.
How Does it Work?
In order to produce electrical power, the real energy 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 through turbines with steam. Normally, most geothermal plants harness energy via heated water. Nevertheless, new technology is being produced that can 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 one geothermal plant which produces about 25 megawatts of energy for about 5 cents per watt. In total; 1 geothermal plant accounts for about 1/4 of the entire states electricity. One geothermal plant accounts for the same power as about three nuclear plants. This is simply because geothermal energy is run 24/7 as opposed to nuclear plants which spend time switching fuel rods and shutting off the core each night.
Abundance?
Wherever there’s earth, there’s geothermal power. 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 should dig deeper to access much more heat.
Environmental Effects?
The only waste produced is going to become heat; not so bad! Also, geothermal energy plants are smaller than most, reducing visual pollution and preventing sights like “wind vane forests”.
So there you’ve it. Geothermal Power offers promising gains for humanity. With the efficiency of nuclear energy without the waste or visual pollution, it provides the greatest gains of any from the alternative fuels.
