Source of All Geothermal Energy

Hello again,

It is important to remember that the sun is the source of all geothermal energy. NASA has some spectacular videos that give you a feel for the power of our sun! Try this video on for size (careful, it can be mesmerising). According to the leader on the video, this 15 minute video required about 150 hours of special technicians’ time to prepare. It is made from ten different wavelength exposures, each shown in different colours here, taken every 10 seconds.

P.S. If you get a white box with or without advertising in the middle of the screen, you can cancel it, Mouse-over the upper right corner area – when you see a small black circle with an “x” in it, click on it. That should close all the garbage and give you an unrestricted view. It is even more spectacular full screen!

How Does Geothermal Energy Work

How does geothermal energy work is a good question, and one which I have often been asked. In this article I must first explain what it is, and then how it can be made to work for man.

Geothermal energy is, literally, the heat of the earth. The heat itself derives from radioactive decay beneath the earth’s surface and, in certain locations, it is concentrated enough and is close enough to surface waters to be brought to the surface by local geological features.

Geo-energy was once thought of as nothing but a thing to wonder at, but it is thought of very differently, now, and is considered by many as one of the most promising forms of renewable energy. It is a renewable energy source because the hot water which conveys it is replenished by rainfall and the heat it brings with it is continuously produced inside the earth.

The great thing about it is that as a form of energy it is versatile and reliable and it produces electricity which generally produces none of the greenhouse gases associated with the combustion of fossil fuels.

So, geothermal energy is the power which can be generated by the harnessing of the heat beneath the Earth’s surface. Deep wells are usually used to pipe steam and hot water from deep within the Earth, up to the surface.

Geothermal heat comes from the magma in the earth’s core, and that itself is heated by the radioactive decay of uranium, thorium, and potassium present in the core. Geothermal energy is present everywhere beneath the Earths surface, although the highest temperature, and thus the most desirable, resources are concentrated in regions of active or geologically young volcanoes.

Though the resource is thermal energy rather than a physical substance such as gold or coal, many aspects of geothermal energy are analogous to characteristics of mineral and fossil-fuel resources.

Geothermal energy works for us when, for example, is used as to warm the water in fishing farms. The water is heated, and the warmth makes it more possible for alligators, tropical fish, and other types of fish to grow in seasons and places where they wouldnt normally.

There are some limitations to it as a form of energy. Unfortunately, the best geothermal resources are concentrated in areas of volcanic activity and are not widely distributed. The earth’s centre is a distance of approximately 4000 miles from the surface and is so hot that it is molten, but when the heat does not rise to the surface it is too far to drill down to the center.

When used in a power station geothermal heat from the hot water from the well causes a secondary fluid to turn into vapor, which as it expands drives the turbines to produce electricity. Since the technology used in a binary-cycle geothermal power plant is a closed-loop system, nothing is emitted to the atmosphere. After turning the turbine generator, the working fluid is condensed back into liquid, which is repeatedly vaporized by the geothermal heat in a continuing cycle.

Dry steam and flash steam power plants do emit low levels of carbon dioxide, nitric oxide, and sulfur, although reportedly at only roughly 5% of the levels emitted by fossil fuel power plants. However, geothermal plants can be built with emissions-controlling systems that can inject these substances back into the earth, thereby reducing carbon emissions reportedly to less than 0.1% of those from fossil fuel power plants.

Dry steam plants are used when the rock is very hot. They take steam out of fractures in the ground and use it to directly drive a turbine that spins a generator. Flash plants take hot water, usually under pressure and at temperatures over twice the normal boiling point of water, out of the ground. They allow it to boil as it rises to the surface then separates the steam phase in steam/water separators and then run the steam through a turbine. The turbine also turns a generator, and from that comes the electrical power.

Temperatures in the Central Texas hydrothermal aquifers range from about 90 degrees Fahrenheit to 160 degrees F at depths from 500 to 5,000 feet. Historically these waters have seen some application in spas and therapeutic baths, but might also be developed for geothermal winter heating if used with heat pumps.

If you were to ask the average Icelander; How Does Geothermal Energy Work. He would probably say; very reliably and, our country shows how it can work very well.

Iceland takes advantage of its incredible geological structure to use geothermal power to their advantage. Recently, it has been reported that 17% of Iceland’s total electricity production comes from geothermal energy. Iceland has reached uniquely high levels in the utilization of geothermal energy, but the resource could be better utilized globally. Iceland is very lucky when it comes to energy as it gets almost all of the rest of its electricity from Hydro-power dams.

Energy from geothermal sources today has been said to amount to less than 0.1 percent of the global world use.

Currently in the US, the author understands that, only four states generate electricity from geothermal resources. In total, this provides electricity for about 3.7 million people.

Why Geothermal Energy is so Beneficial

As organic based fuels become 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 are natural, not all are available 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 find energy that is cheap, renewable, and ecologically friendly. Despite using the sun, wind, water, and nuclear energy for electricity, there is still one natural resource that has yet to be harnessed. One that is cheap, abundant, and effective: geothermal energy.

In order to fully understand why geothermal energy 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 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 almost everywhere in the world.

How Does it Work?

In order to produce electricity, the real energy source used 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 taken from rocks and hot springs radiates through turbines with steam. Normally, most geothermal plants harness energy through heated water. However, 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 of the entire states electricity. One geothermal plant accounts for the same energy as roughly three nuclear plants. This is because geothermal energy is run 24/7 unlike nuclear plants which spend time switching fuel rods and shutting off the core each night.

Abundance?

Wherever there is earth, there is 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 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 have 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 of the alternative fuels.
