As organic based fuels become much more scarce, scientists are pushing for the research and development of green alternative fuel. A plethora of potential power 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 another option, one that’s 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 discover energy that’s inexpensive, renewable, and ecologically friendly. Despite using the sun, wind, water and nuclear power for electricity, there’s stil one organic resource that has yet to become harnessed. 1 that’s inexpensive, abundant, and effective: geothermal energy.
So that you can fully understand why geothermal power is so important, here is a broken down explanation.
What Exactly Is Geothermal Energy?
Geothermal energy (literally heat from the earth in Greek), is a phenomena caused by the constant decay of minerals in the earth, absorption of the sun’s rays, and also 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 discovered almost everywhere in the world.
How Does it Work?
In order to produce electrical power, the real energy source utilized in homes and offices, turbines require to become spun at power plants which charge a generator. Water and wind directly charge the generator although sun and nuclear energy indirectly turn them via steam. With geothermal energy, heat taken 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 energy 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; one geothermal plant accounts for about 1/4 from the entire states electrical power. 1 geothermal plant accounts for the same power as roughly three nuclear plants. This is because geothermal energy 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 is earth, there’s geothermal energy. However, land near tectonic plates, where volcanos, earthquakes, and geysers are found, 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! Also, geothermal power plants are smaller than most, reducing visual pollution and preventing sights like “wind vane forests”.
So there you’ve it. Geothermal Energy offers promising gains for humanity. With the efficiency of nuclear power without the waste or visual pollution, it offers the best gains of any from the option fuels.
