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.

With people looking for more and more ways to find renewable energy sources, many don’t realize they are standing on top of one of the greatest energy resources on the planet. The Earth’s core is at an unbearable temperature, hotter than anyone could possibly even fathom. This heat builds up so much pressure in the Earth’s core that it has to be released in some way. These releases are known as geothermal energy. The hot water and steam from the Earth can be used in a number of ways to create energy. This is a renewable energy because the heat in the Earth’s core is constant and the water replenishes from rainfall.

There are different ways to use geothermal energy that include direct and indirect uses.

- The heat from the Earth could be used as a direct source for heating systems. The hot water close to the Earth’s system is directly pumped into heating systems.

- Generators in power plants require steam at very high temperatures to work. Geothermal power plants are built near reservoirs to tap the natural resource. The power plants use steam or water close to the surface to operate its generator.

- Geothermal heat pumps use water near the Earth’s surface to control building temperatures. This renewable energy source can regulate entire towns and villages.

Using geothermal energy isn’t a new concept. History has shown that people in ancient times have used hot springs for cooking, bathing and heating purposes. Even today many believe that natural hot springs have healing powers. There are many people who still bathe in hot springs. In Reykjavik, Iceland 95 percent of the buildings are heated with geothermal district heating systems. Hot water near the Earth’s surface is pumped directly into the buildings.

The Unites States is one of the leaders in geothermal power. The country has more geothermal power plants than any other, however, it only accounts for one percent of the electricity produced in the U.S. California (33), Nevada (15), Hawaii (1) and Utah (1) are the only states with geothermal power plants.

There are opponents of geothermal energy. While there are uses for it, criticisms have been raised. Some believe this is not a long term solution nor could it be used in huge environments. There are others who think creating geothermal power plants would cost too much money and drain money from researching other valuable energy resources. People are also concerned that if magma is tapped, it could bring up dangerous and harmful particles.

One thing is certain, more research is needed to make an educated conclusion about geothermal energy. There is too much guessing going on and not enough doing. There are results of natural geothermal reactions. These happen everywhere and come in the form of volcanoes, hot springs and geysers. With geothermal reactions occurring naturally, humans should find a safe way to tap into it.

After heating and cooling, water heating is typically the largest energy user in the home because it is necessary for so many domestic activities. Whether you are replacing a worn-out existing water heater or looking for the best model for a new house you are building, it pays to choose carefull

Here you can learn how to use the energy in your home more efficiently. You can also learn how to use renewable energy to provide your home with electricity, heating, cooling, and water heating.

Alternative energy from sources that do not produce harmful emissions. For example, unconventional power from the sun, wind or running water. In most boilers, wood, coal, oil or natural gas is burned in a firebox to make heat. Running through the fire box and above that hot fire are a series of pipes with water running through them. The heat energy is conducted into the metal pipes, heating the water in the pipes until it boils into steam. Water boils into steam at 212 degrees Fahrenheit or 100 degrees Celsius. Why waste this energy use it, don’t loose it.

If you currently have an electric water heater and natural gas is available in your area, a switch might save you a lot of money. Even though electric models have a higher energy factor than fuel-burning models, electric resistance is a very expensive way to generate heat. It does not have great environmental benefits either, since electricity is only as clean and efficient as the fuel (often coal) that generates it. Before you rule out electricity, though, check with your utility company. It may offer special off-peak rates or options for purchasing renewable power that may make electricity a more attractive option for you.

A renewable resource is fairly easy to replace. Renewable energy resources include wood, wind, sunshine, geothermal energy, biomass, and water stored behind dams in lakes and reservoirs. Electricity can be produced using several kinds of renewable resources.

From space, oceans look much different than adjacent land areas – they often appear darker, suggesting that they should be absorbing far more sunlight. But unlike dry land, water absorbs energy in a dynamic fashion. Some of the solar energy contacting the surface may be carried away by currents, some may go into producing water vapor, and some may penetrate the surface and be mixed meters deep into the water column. These factors combine to make the influence of the ocean surface an extremely complex and difficult phenomenon to predict.

Some countries give tax credits for the use of alternative renewable energy. In todays world we as a population should endevour to protect our environment and the use of alternative and renewable energy is a must do if we are to survive on this planet. For us not to consider the impacts of our enegy use would severely impact on the lives of those well into the future. So look after mother earth as she needs to be looked after and by using renewable resources we can limit our impact.

If you are concerned about how modernization affects the environment and if you are looking for new investments, investments in alternative energy mutual funds may be the perfect solution.

Alternate energy mutual funds invest in companies that are developing ways to produce energy without harming the environment. You can join the huge movement of people who are interested in making money from alternative energy.

The world comes closer and closer to an energy crisis as the non-renewable sources of energy such as coal and oil, which are are major sources of power, become more depleted. This is the reason so many companies are scrambling to develop alternative sources of energy. They need money to do this, and alternative energy mutual funds can supply the money.

A mutual fund is an investment company that looks for small companies that have growth potential and then it invests in them. Remember the Microsoft story: a small company that was started in a garage.

Alternative energy mutual funds specialize in investing in companies that develop alternative energy. Some do this solely because they believe it is better for the earth. But others see alternative energy as the only option for power for the future.

Alternative energy is culled from the natural resources of the earth, such as wind, sun and air. Unlike the non-renewable sources of energy, these sources will continue into the future. People who invest in alternative energy mutual funds may not have to worry about their future! But there are risks to be considered with alternative energy mutual funds.

But all businesses have risk.

There are some viable alternative energy technologies that are not yet cost effective. The alternative energy mutual funds need to be selective about which firms they invest in. They have to make sure the company meets the environmental standards they may have, as well as the ability to use new technogies.

Change is inevitable, and everything in the world changes constantly, including people, their governments and their policies. These changes affect the companies that alternate energy mutual funds invest in.

How a company develops and grows will be determined by factors such as opportunities available and risks encountered. It is possible to make or lose a lot of money. But this, like everything in life is a gamble.

Alternative energy mutual funds have been primarily investing in other countries so that they can keep their investments diversified and take advantage of growth opportunities. But there are foreign exchange risks in this.

Alternative energy mutual funds are run by human beings, who are always prone to mistakes. One of those mistakes is to think they are investing in a company that has an alternate source of energy when all they are doing is adding additives to change the chemical makeup of the energy source. This is not a joke. Since the regulation of these companies is not strong, scams like this can happen.

There are many more riks that may have to be faced when considering investing in alternative energy mutual funds. But sometimes the end, helping the earth, is worth the risk.
