Geothermal energy comes from the ground, and it’s a natural source. The first geothermal power station was built at Larderello, in Italy, and the second at Wairekei, in New Zealand. Others are in Iceland, Japan, Philippines, and United States.
Prince Piero Ginori Conti tested the first geothermal power plant on July 4, 1904. It was at Larderello dry steam field in Italy.
Geothermal energy, energy contained in intense heat that flows outward from deep within Earth. This heat originates primarily in the core. About four feet underground, the temperature of the earth stays the same all year long about 55 degrees.
A geothermal power plant simply skips the burning stage. The steam comes directly from the ground, and then turns the turbines. Electricity is made and sent along wires. Geothermal power can also make a hot water and steam heat to be sent straight homes.
“Geo” means “from the earth” and “thermal” means “heat”, so this type of energy is found under the earth. Geothermal energy does not produce any pollution, and does not contribute to the greenhouse effect. Iceland uses geothermal energy the most.

Having power cuts???
Here’s why you should use Geothermal Energy
Geothermal Energy is the best energy to use. First of all it is environmentally friendly and it is also very reliable.
Geothermal Energy is generated in the Earth’s core. It is found about 4,000miles beneath the ground. Using pipes they suck out steam which then turns the turbine. This is basically Geothermal Energy.
Geothermal Energy is clean and safe for the environment. It is actually the safest. It has little or no harmful gases and gives out very little waste. Geothermal Energy also produces less ozone than various other sources of energy like fossil fuels, solar energy and so on. This is good because ozone is harmful to the ground but good for the atmosphere.
Geothermal Energy uses renewable energy, unlike fossil fuels which use coal and oil for its resource. Both coal and oil are non-renewable resources. Geothermal Energy uses the Earth’s core for its source and it can never run out. It is sustainable as it can be stored for a long time.
The Geothermal Power Plant is unaffected by weather changes. This keeps the Power Plant working continually. Hence there is an uninterrupted supply of power at all times.
Geothermal Energy is better than other forms of energy because it pollutes the least, does not use non-renewable resources like coal and oil and it is also kinder, cleaner and safer for the environment.

Geothermal energy in affective use
Are you at risk to run out of oil? Use geothermal energy instead of oil to make electricity.
Geothermal energy is steamed water (clean and sustainable) that comes from the earth’s surface. It is also generated in the earth’s core about 4000 miles below the surface. Most geothermal reservoirs of hot water are located in the western states, Alaska and Hawaii.
In order for electricity to work you need oil, but if oil prices go up or if oil is not being sold anymore. So then another way for electricity to be made is geothermal energy. Country’s that don’t have enough oil can just use geothermal energy for electricity to be made. If a country didn’t have geothermal energy then the consequences that country would face is that they wouldn’t have electricity at all.
Geothermal energy is very important because this is another way to make little electricity for people who don’t have oil. So now people can rely on something besides from oil only if country had geothermal energy.

Geothermal Energy Tomorrow
You never know, in the future you might use electricity from Geothermal Energy.
In the future, The United States might change to become a cleaner environment, more sustainable energy system. The cost for the importation will be a lot cheaper. Even all the untouched geothermal resource could be developed. Geothermal Energy, and other renewable resources, will become more important as coal, oil, and other natural gases begin to run out.
Going into the circumstances around the world, the US are producing a high amount of Geothermal Energy, which will let them use 1/3 of it as electricity. In Ohaaki, New Zealand there are a few geothermal power plants. Possibly in the future the power plants might become common. As you probably know, Geysers are a very common tourist attraction. In the future it might be more than just a tourist attraction.
I think that this is important, because we can tell that in the future many countries will be producing their own Geothermal Energy, instead of importing it with a high cost. When more countries produce their own geothermal energy the cost for importing energy will be cheaper, due to the fact that not many countries will need it, except some African countries like Kenya etc. The best part is that, countries that are producing a lot of energy might be using a proportion for electricity.

Does Geothermal Energy Harm the Environment?
Geothermal Energy might be a little bit harmful, but we SHOULD still use it. The harmful things will be answered in this paragraph.
Geothermal Energy is important because we can use it. And if we use it, it would be easier than electricity. Electricity cost, nowadays, a lot of money and on day we might run out of it! So this is one of the reasons we should use geothermal energy.
A lot of countries in the world use geothermal energy. Some of the countries are Hawaii, Kenya, Italy, Canada, and Iceland. In Italy, Larerello Southern Tuscany there was the first Geothermal Power Plant invented in 1911 by UNKNOW PERSON. The first water used was water from baths. Now the water is natural.
Some people all ways ask, how does geothermal energy impact the environment society? That’s what I’m about to tell you. Geothermal Energy can effect the environment by, if they take to much water from the ground and don’t replace it, the land might shrink and sink. If the under ground gases can escape. The gases would smell very bad or pollute the earth. The noise pollution would be as loud as a jet aircraft take off when the gases are released from their tanks. Geothermal energy is important to me because we can help save the earth by this although it had some bad causes to itself.

Geothermal Energy: Our new worldwide power source?
Geothermal energy, one of the energies used other than fossil fuels, is an energy that doesn’t cause pollution and is renewable.
It is made when water goes down till it meets the core, heats up extremely, and comes back up in steam, which is used as energy. Geothermal energy is used all over the world, but is hard to make in countries with more poverty; since geothermal power plants need space and cost lot’s of money.
This energy is significantly better than fossil fuels, as there is an infinity supply of it, since it’s merely made of water, then turned into steam. Geothermal energy’s a substitute for fossil fuels, which there is a limited amount of on this planet. Soon enough, we will have no choice but to use other alternative sources of energy, such as hydroelectric or geothermal energy.
This source of energy can be found in parts of Asia, North and South America, and the Pacific and Atlantic Ocean. Though the water is primarily heated in the core, where temperatures range from four thousand degrees to seven thousand degrees Celsius (seven thousand two hundred degrees to twelve thousand six hundred degrees Fahrenheit), it’s sometimes heated near the crust, which is about five to seventy five kilometers (about three to forty seven miles) thick, while the distance from Earth down to it’s center is about six thousand five hundred kilometers (about four thousand miles) thick.
Personally, I think geothermal energy is extremely important, as it’s a much better source of energy than fossil fuels environmentally, since it does not cause pollution and is renewable, as I have stated in the beginning of this article. Though remember this: Eventually, Earth will run out of fossil fuels, so it’s a good idea to start using alternative energy sources now.

Earth's Spraying Energy
To get Geothermal energy we must drill deep down in the earth. When you drill holes deep down in the earth you have advantages and disadvantages.
If you drill down into the earth you have to do it in a power plant which is not environmental friendly, because you have to cut down a lot of trees and some plants takes up a lot of space.
Geothermal energy works when you drill deep holes in the earth and when water goes into the holes and heats up because the inside of the earth is hot. The steam shoots up like a geyser, and makes a turbine spins which creates electricity.
The advantage of geothermal energy is that it is not pollutant source, not much fuel needed, is renewable, Once you build a power plant the energy is almost free it may need some energy to run a pump, does not contribute to the greenhouse gases.
The disadvantage of geothermal energy is that hazardous gases and minerals may come up from the geysers and they are hard to dispose off. Sometimes time’s geothermal sites run out of steam, perhaps for decades.
Geothermal energy is used near the borders of Asia, Australia, North America, and South America. People also call all these places The Ring of Fire because they make a shape of a ring. The Power plants are all around boundaries near earthquakes and volcanoes because the water that goes down in the holes comes out faster due to the volcanoes heat.
