The heat of the Earth makes up what is known as geothermal energy. When dust and gasses from Earth mixed together 4 billion years ago, geothermal energy resulted.

Inside the Earth at its core, some 4, 000 miles deep, the temperature is estimated at about 9,000 degrees Fahrenheit. Geothermal energy has been used throughout history for bathing, relaxing, cooking and heating. It was thought by some to have healing effects and was used to treat eye and skin diseases. The first geothermal generator that produced energy was built in Lardarello, Italy in 1904. The United States followed with their first attempt at geothermal power in 1912 at The Geysers in California. Today it is produced in twenty-one countries around the world.

Geothermal energy is located deep in the ground. The heat at the core of the Earth has an outward flow. As it moves, it is transferred to surrounding rock layers called the mantle. As temperatures and pressure increase, the rock melts and becomes magma. The magma moves toward the surface of the earth carrying the heat with it. If the magma reaches the Earth’s surface, it becomes lava. However, most of it stays below the Earth’s crust and heats rocks and water that surround it. These temperatures can reach up to 700 degrees Fahrenheit. When the water travels to the Earth’s surface, it becomes hot springs or geysers. Mostly it stays trapped in fractured, porous rocks called geothermal reservoirs. This heat near the Earth’s surface becomes a form of energy.

Hot water or steam from the reservoir exerts a force that can spin a turbine connected to a generator and produces electricity. The cooled water is then returned to the reservoir in order for it to reheat. Much exploration and testing needs to be done to determine where the geothermal underground waters are. When ideal spots are located, drilling is done to create production wells that bring the water to the Earth’s surface for power generation in geothermal power plants.

Although the costs to construct geothermal plants and geothermal wells are high, the cost of producing electricity is lower over time. The fuel is reliable, stable and does not need to be transported. The white smoke you will see over geothermal power plants is not smoke but rather steam. During the process of operations it may, however, bring some hazardous gases from underground.

The United States stands as the biggest producer of geothermal energy. Unfortunately, interest in it is low and it only accounts for about 1% of this country’s energy supply. Through research and experience new methods and technologies for accessing geothermal energy will improve. Tapping into the heat under the Earth’s surface can produce much more of the nations energy. We are at a point where renewable energy sources must make their way to the forefront of the energy picture. Not only are fossil fuels being depleted, but also they are ruining our air quality. In time, geothermal energy may become an appealing alternative. Competitive pricing and minimal environmental impact could produce a hot future for this renewable energy source.

Sunlight, geothermal heat, wind, tides and rain are natural resources that can help generate energy and it is called renewable energy. In 2006, 18% of energy consumed globally came from renewable energy and 13% came from traditional biomass, which includes wood-burning.

The next largest renewable energy source is Hydroelectricity which provides 3% (15% of electricity generated globally), followed by solar hot water/heating, which contributed up to 1.3%. 0.8% of the final energy consumption is provided by wind power, geothermal energy, ocean energy and solar power.Every year, wind power grows at the rate of 30 percent, with a capacity of over 100 GW installed all over the world and is widely used in the United States and in several European countries. In 2006, the photovoltaic power stations manufactured more than 2,000 MW and these photovoltaic (PV) energy stations are quite popular in Spain and Germany

Renewable energy such as solar thermal power can be found in the Spain and in the USA, the Mojave Desert’s 354 MW SEGS power plant is the largest. If you go to The Geysers in California, you can find the world’s biggest geothermal energy installation. The rated capacity of the geothermal power installation is 750 MW. One of the largest renewable energy programs in the world can be found in Brazil, involving using sugar cane to produce ethanol fuel, and ethanol contributes 18 percent of the Brazil’s automotive fuel. In USA, ethanol fuel is also widely available

Even though there are many large-scale renewable energy production and projects, renewable energy technologies are also recommended for remote and rural areas, where energy is very important for human development. Kenya’s household solar ownership is the highest in the world. About 30,000 small solar power systems (20-100 watt) are sold per year.

The market for the many forms of renewable energy is increasing even though some renewable energy technologies were criticized for being unsightly or intermittent. High oil prices coupled with the climate change concerns and increasing government support are driving increasing incentives, renewable energy legislation and commercialization.Renewable energy industries will be able to weather the 2009 economic crisis better than many other sectors with the new government regulation, spending and policies

One of the most natural forms of energy that you have in existence today is geothermal energy. This energy comes from the heat present within the earth and it can be employed in a variety of different forms. The origins and the application of geothermal energy are explored in this article.

Geothermal energy is the Earth’s heat. It is the end result of the fusion of dust and gas which happened about four billion years ago.

Deep inside the earth’s core and approximately about 4,000 miles deep, the temperature is about 9,000 degrees Fahrenheit. Geothermal energy has been used for everything from bathing to relaxation and cooking as well as heating. The first geothermal generator was created in Italy at the beginning of the 20th century. In 1912 the United States followed with their attempt at creating geothermal power with The Geysers in California. The energy is now produced in over 21 countries of the world.

You can find geothermal energy deep in the ground. The heat at the core of the Earth flows outwards. When it flows the heat is transferred to surrounding rock layers known as the mantle. When temperatures and pressures increase, the rock then melts and becomes magma. Magma then moves to the surface of the earth and takes along the heat with it. If magma gets to the surface of the earth it becomes lava otherwise it stays below the earths crust and heats up the rocks and surrounding water. These temperatures can get as high as 700 degrees Fahrenheit. When water travels to the surface it becomes hot springs or geysers. Most of this water however gets trapped in fractured and porous rocks which are known as geothermal reservoirs. The heat also becomes a form of energy.

Hot water or steam that comes from a reservoir can easily exert a force that spins a turbine connected to the generator in order to produce electricity. Cooled water is then returned to the reservoir in order to reheat. In order to determine other locations of geothermal underground waters further research, exploration and testing are required. When the necessary spots have been located, drilling can then be carried out in order to create the production wells that supply water to the surface of the earth in order to generate power in geothermal plants.

The costs of constructing geothermal plants and geothermal wells are quite high, the costs of producing electricity tends to be much less over time. The fuel is reliable and stable and has no need for transportation. White smoke that is seen over geothermal power plants isn’t smoke but steam. During operations however, hazardous gases may be brought up from the underground.

The United States is the biggest global producer of geothermal energy. Unfortunately the global interest in geothermal energy is low and only accounts for a small portion of the global energy supply. Research and experience will produce new means and technologies that will aid you in accessing geothermal energy. Renewable energy sources must become the major source of energy in the years to come. Fossil fuels are constantly being depleted and reducing the quality of air that we enjoy. Over time geothermal energy might become much more attractive. Reduction in the costs of implementation of this energy source might in time lead to a better future for this source of renewable energy.
