As organic based fuels turn out to be more scarce, scientists are pushing for the research and development of green alternative fuel. A variety of potential energy sources have been suggested: wind, solar, water, and nuclear to name a few. Although they are natural, not all are obtainable globally 24/7. There is another option, one that is perpetual and found 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 is cheap, renewable, and ecologically friendly. Despite utilizing the sun, wind, water and nuclear energy for electricity, there’s stil one natural resource that has yet to become harnessed. One that is inexpensive, abundant, and efficient: geothermal energy.

In order to fully comprehend why geothermal energy is so essential, here is really a broken down explanation.

What Exactly Is Geothermal Power?

Geothermal energy (literally heat from the earth in Greek), is a phenomena caused by the constant decay of minerals within 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. Simply because of this, it is perpetual and is discovered almost everywhere within the world.

How Does it Work?

So that you can produce electrical power, the real energy source utilized in homes and offices, turbines need to be spun at power plants which charge a generator. Water and wind directly charge the generator while sun and nuclear energy indirectly turn them through steam. With geothermal energy, heat extracted from rocks and hot springs radiates via turbines with steam. Usually, most geothermal plants harness energy through heated water. Nevertheless, new technology is being produced that can harness thermal power 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 one geothermal plant which produces about 25 megawatts of power for about 5 cents per watt. In total; one geothermal plant accounts for about 1/4 from the entire states electricity. 1 geothermal plant accounts for the same power as approximately three nuclear plants. This is simply because geothermal power 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 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 must dig deeper to access much more heat.

Environmental Effects?

The only waste produced is going to be 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 provides 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.
