As organic based fuels become much 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’re organic, not all are obtainable globally 24/7. There’s one more 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 inexpensive, renewable, and ecologically friendly. Despite utilizing the sun, wind, water and nuclear power for electrical power, there’s stil one natural resource that has yet to be harnessed. 1 that’s cheap, abundant, and efficient: geothermal energy.

So that you can fully comprehend why geothermal energy is so important, here is really 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 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’s perpetual and is found nearly everywhere in the world.

How Does it Work?

In order to create electrical power, the real energy source utilized in homes and offices, turbines require to be spun at power plants which charge a generator. Water and wind directly charge the generator although sun and nuclear energy indirectly turn them through steam. With geothermal power, heat obtained from rocks and hot springs radiates via turbines with steam. Normally, most geothermal plants harness energy via heated water. However, new technology is being produced that may 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 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 from the entire states electrical power. 1 geothermal plant accounts for the same power as around 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 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 much more heat.

Environmental Effects?

The only waste produced 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 Power provides promising gains for humanity. With the efficiency of nuclear energy without the waste or visual pollution, it provides the best gains of any from the alternative fuels.
