Geothermal Energy

You’ve never thought about the earth being like a boiled egg but think about it: If you cut the egg in half the yellow yoke is like the core of the earth and the white part would be the earth’s mantle. The thin shell, discarded after the egg is boiled, is like the earth’s crust.

The geothermal energy, has been around for as long as the earth has existed. “Geo”  means earth, and “thermal” means heat. So geothermal means earth-heat. Geothermal energy is quickly becoming a popular source of energy and GreenDustries believes tapping into what the earth creates naturally – with little manmade influence – should be at the forefront of any energy policy moving forward.

“For every 100 meters you go below ground, the temperature of the rock increases about 3 degrees Celsius. Or for every 328 feet below ground, the temperature increases 5.4 degrees Fahrenheit. So, if you went about 10,000 feet below ground, the temperature of the rock would be hot enough to boil water” .

According our research, deep under the surface, water sometimes makes its way close to the hot rock and turns into boiling hot water or into steam. The hot water can reach temperatures of more than 300 degrees Fahrenheit (148 degrees Celsius). This is hotter than boiling water (212 degrees F / 100 degrees C). It doesn’t turn into steam because it is not in contact with the air.

Temperature in the EarthWhen this hot water comes up through a crack in the earth, we call it a hot spring, like Emerald Pool at Yellowstone National Park. Sometimes it explodes into the air as a geyser, like Old Faithful Geyser.

“About 10,000 years ago, Paleo-Indians used hot springs in North America for cooking. Areas around hot springs were neutral zones,” the site continues. “Warriors of fighting tribes would bathe together in peace. Every major hot spring in the United States can be associated with Native American tribes. California hot springs, like the Geysers in the Napa area, were important and sacred areas to tribes from that area.”

In other places around the world, people used hot springs for rest and relaxation. The ancient Romans built elaborate buildings to enjoy hot baths, and the Japanese have enjoyed natural hot springs for centuries, the site states.

So this type of natural phenomena can be used to our advantage as we begin rethinking our energy policies in the United States and abroad. At GreenDustries we think that the effort to change our energy direction is unmatched by the results we can achieve.

  1. It’s really great that pepole are sharing this information.

  2. Hi there, just became aware of your weblog by way of Google, and identified that it is genuinely informative. I

    We reach our goal! We want to inform the public of what is really going on with our surrounding, after all it’s our future and the one of our children!
    Thank you.

    If we want to help to change what is today, we have to talk about all this.
    The world is blocked in the past.
    Thank you.
