Last year we wrote an article on the uses of geothermal energy. Here is an updated version of that article with additional information. 1. Aquaculture and horticulture: Geothermal renewable energy is used in aquaculture, and horticulture, in order to raise plants and marine life that require a tropical environment. The steam and heat is all supplied by geothermal energy. 2. Industry and agriculture: Geothermal power generation is playing an increasing role in industry and agriculture. Timber is dried using heat acquired from geothermal energy, and paper mills use it for all stages of processing. The potential uses of geothermal energy in industry are huge. 3. Food Processing: The earth naturally contains an endless supply of heat and steam, which can be utilized to sterilize equipment and rooms. This would put an end to the use of chemicals for this purpose. There are many potential uses of geothermal energy in food processing, but as yet, this renewable energy source has yet to be utilized to a large degree in this sector. 4. Providing heat for residential use: Geothermal renewable energy has in the last few years caught the interest of an increasing number of house owners. Geothermal power generation provides more than just heat in summer; but a complete temperature control system which enables you to cool your home in winter as well. This significantly reduces heating and cooling bills, and keeps the home at a comfortable temperature year round. 5. Electricity generation: A geothermal power station works in a very different way to the geothermal power generation that would be used in the examples above. It provides not just heat and steam, but electricity itself. Geothermal power generation is completely clean, and releases no harmful gas emissions whatsoever. Many readers of this article will be most interested in single-home geothermal energy. As was explained, its use is limited to heating and cooling. However, indoor climate control can consume an enormous amount of energy in a big house, and by installing a geothermal heat pump this energy bill can be greatly reduced. Geothermal heat pumps move heat from below the ground into the home in winter and draw heat from your house into the ground in summer. Most geothermal energy pumps are simple and require little maintenance. They are not, however, a full-service solution. Some systems reduce energy bills by up to 40%, so you cannot get rid of your utility company straight away. One option is to install a small solar panel system to run the pump, and in doing so make you completely self dependant. A geothermal energy pump which can supply an average home’s needs costs around $8,000, however, the drilling and installation process cost in the region of $30,000.

Geothermal energy companies are America's future when it comes to energy sources. There are many advantages of geothermal energy. For one, geothermal renewable energy is good for the environment, as it is a good reliable energy source that is low-impact, and it is a cost effective source of energy. Geothermal energy companies are tapping into a quality, continuous source of energy that I believe will compose a lot of America's energy future. But first, what is geothermal energy? Geothermal energy is power that is extracted from heat from the earth. It is a renewable energy source that until recently was only able to be used from areas near tectonic plates, where high temperature energy sources are available relatively close to the surface. Recently however, geothermal energy companies have been able to utilize the Earth's heat away from tectonic plates. For example, there are several facilities in Europe that utilize geothermal renewable energy, such as one in Landau-Pfalz, Germany and Soultz-sous-Forets, France. A similar so-called demonstration project was shut down in Basel, Switzerland because it triggered a series of earthquakes, but it is not common for that to occur.

1. Aquaculture, Horticulture, And Thermoculture

Geothermal renewable energy can be used for aquaculture, horticulture, and thermoculture. This renewable energy can be used to raise plants and marine life that needs warm waters and a tropical environment. Greenhouses can use geothermal power generation to keep plants warm and moist, with the steam and heat being provided by geothermal energy. Geothermal renewable energy is used to heat the worlds only geothermally warmed prawn farm, and in the year two thousand and five this prawn farm sold twenty tons of prawns raised on the farm. Using geothermal power generation can also provide electricity to these projects as well as heat and steam.

2. Industrial And Agricultural Uses

Geothermal power generation can play a big part in industrial and agricultural operations around the world. Geothermal renewable energy can play many roles in these sectors. Timber can be dried using heat from geothermal energy, and paper mills like one that is located on a geothermal field in New Zealand can use this energy in almost every stage of paper processing. There are thousands of industrial and agricultural uses that geothermal energy may be perfect for, and the cost of this energy is very low once the geothermal power generation facility is in place and operating.

3. Food Processing

The food processing industry is one that can benefit greatly from geothermal renewable energy. One way that this energy source can be invaluable is as steam for sterilizing food processing facilities. The earth naturally contains high levels of heat and steam, and releasing this steam can sterilize equipment and rooms without using drugs or chemicals. This will prevent any microorganisms from becoming resistant to these substances and developing more harmful strains. Geothermal energy can also help dry out plants, making powders and concentrates that are used in food processing, and at times these substances can be used to add flavors or preserve foods without any unnatural additives. Foods can be cooked, steamed, or prepared in other ways using geothermal energy as well.

4. Providing Heat For Residential And Commercial Use

Geothermal renewable energy can be used to provide heat for all types of buildings, from homes to businesses to farms, barns, and other types of buildings. Using this energy does not just provide heat, it is a complete temperature control system which can help cool your home as well. With a geothermal heating and cooling system you will see much lower energy bills, because a furnace or air conditioner is not needed. These appliances can use a substantial amount of electricity, running up utility bills and wasting energy. Geothermal temperature control units can add heat or pull it out of your home or other type of building, keeping it comfortable all year long.

5. Electricity Generation

A geothermal power station can provide a large amount of electricity, with many benefits that using fossil fuels for electricity generation do not offer. Geothermal power generation is very clean, because it uses the heat and steam trapped in the earth to produce electricity. There are no harmful gas emissions or high carbon levels, and these power generation plants do not contribute to air pollution. This energy source is renewable, and does not depend on fossil fuels or foreign countries to supply energy the country needs. Geothermal energy can add stability to both the cost and the availability of electricity and heat for the entire world. Fossil fuels will run out in the near future, and an alternative renewable energy plan needs to be in place to ensure that an energy crisis does not occur. Geothermal energy can help meet these needs.

• Many people wonder how geothermal power work
• Geothermal power generation uses steam and heat from the earth to generate electricity and heat buildings
• A geothermal power station is extremely clean and eco friendly

How does geothermal power work? Geothermal power generation starts with the heat that is in the earth, and this power is a renewable alternative energy source that does not have the harmful effects that oils and other fossil fuels do when it comes to pollution, using up limited resources, global warming, ad greenhouse gas emissions. Geothermal renewable energy is a great way to use the heat from the earth for our energy purposes, without causing any more damage to the earth or using up all of a natural resource. Fossil fuels are in limited supply, and they cause damage to the earth and environment. A geothermal power station can efficiently use the heat in the earth for clean energy which has no negative environmental effects.

Geothermal power generation starts with the steam and heated water that is present inside the earth, under the crust and deeper. These are used to generate electricity and to provide heat for homes and other buildings. Geothermal hotspots are located, such as hot springs and areas where the crust of the earth is thin. There are several of these areas in the southwest United States, places where geysers and other geothermal activity occurs frequently above the earth. The ideal temperature is one hundred degrees Celsius, because this is the temperature needed to boil water and make steam from water. There are several ways that geothermal energy can be captured and used for heat and electricity.

In some countries where these geothermal spots are located, a pipe may be tunneled into the earth to release the heat and steam to heat homes. Sometimes a geothermal power station will be situated above a hot spot, and the steam below the surface is used to generate electricity. Hot water can be pumped below the crust to generate steam, which is then captured and used in geothermal power generation. Another method is to run pipes through hot magma rocks, and circulate water through these pipes. The water is turned to steam using the heat of the rocks, and there is no harmful environmental damage.

Another method of geothermal power generation is to take advantage of magma from volcanoes. Even when only partly liquid this substance has a temperature of at least six hundred and fifty degrees Celsius, more than six times hotter than the heat needed to boil water. This magma is used to boil water into steam, which powers steam turbines to generate electricity. Situating these power plants near areas of high volcanic activity but low damage risk can create a substantial amount of electricity.

How does geothermal power work? The heat from the earth is used efficiently to create electricity and to heat buildings by creating steam. With global warming speeding up and pollution and smog at all time highs around the world, fossil fuels are no longer an option. Because geothermal power generation does not use fossil fuels, and is a clean renewable energy source, this alternative energy source may become the most commonly used source in the future. This energy generation form has many advantages, and no disadvantages. The earth will continue to create heat, because of the radiation process that continues nonstop. There will always be rainfall that replenishes the water underground. Because of these facts, geothermal is a viable renewable energy source that is kind to the earth, the environment, and all living things. There are many geothermal hot spots that could be used as a location for power plants, and these facilities do not cause environmental damage because they only use water, steam, and the heat from the earth. There are no harmful chemicals or toxins used, and there is no pollution into the air.

Geothermal alternative energy shows enormous potential in supplying some of the energy needed in America, but many people wonder how to calculate geothermal heating costs. There are many factors that need to be looked at to determine the exact cost of geothermal heating, and this includes the costs financially, the cost to the environment, and the costs of installation, operation, and maintenance on the geothermal heating system you choose. Homes can have residential solar powered systems that supply both heat and energy, along with a geothermal heating system. Compared to the cost of installing a typical furnace and heating system that uses fuel oil or another fossil fuel energy source, buying and installing a geothermal heating system may cost more up front by a significant amount. Once the system is installed, however, the costs associated with geothermal heating systems are much less than other heating systems. There is only one energy bill per month, because a geothermal energy unit can both heat and cool your home. Geothermal heating systems also cost much less to operate and maintain than traditional heating systems do, making them last longer and less expensive to maintain in good operating condition.

Government incentives are available for homes which use solar energy technology or geothermal heat systems. These incentives also must be considered when looking at the total geothermal heating costs. Government credits and subsidies can bring down the initial cost of installing geothermal heating in your home by offsetting some of the large initial costs for these systems. The Energy Improvement and Extension Act of 2008 gives even more incentives for homeowners and car buyers to consider alternative energy sources as a source of heat and power. Residential solar power systems and geothermal heating systems can make your home much more cost effective and energy efficient, while at the same time helping out the environment and preventing pollution and energy waste.

Investing in solar energy stocks can be another way to benefit from alternative energy and geothermal heating. Solar energy stocks are companies that are in the solar energy industry, and these companies may make solar energy panels, install solar energy equipment, or include any other aspect of the solar energy process. Solar energy and geothermal heating can work together to make each of these technologies more efficient when combined. Having both residential solar power systems and geothermal heating systems in your home is like having a one two punch that ensures alternative energy use and efficiency together. Solar energy technology makes energy from the sun available for use as electricity or heat, reducing the need for fossil fuels, and lowering your dependence on them. These technologies also save you money, with lower utility bills. Solar energy stock investments can provide an investment into green alternative energy sources.

To accurately calculate geothermal heating costs, all of the contributing factors must be assessed and evaluated. The purchase and installation costs must be evaluated, plus the operation and maintenance costs must be included as well. The impact on the environment must also be determined from the heating method used. Geothermal heating systems are friendly to the environment, and do not contribute to global warming or pollution like some fossil fuel heating systems do. This process will allow you to determine the total cost of geothermal heating for you and your home. Geothermal heating is one answer to our dependence on foreign oil and fossil fuels, and this answer can be extremely effective. Another benefit of geothermal heating is the fact that after the initial high cost of purchase and installation, these systems cost less than other heating systems to operate and maintain.

The future of energy will include alternative renewable energy sources like biomass energy, which includes biofuels such as ethanol and biodiesel. Other renewable alternative energy sources are wind energy, solar energy, geothermal energy, wave energy, and others. Fossil fuels will no longer need to be used, which would reduce harmful emissions and other dangerous environmental pollutants. Fossil fuels are not renewable because it takes thousands of years for them to accumulate within the earth, and at the rate they are currently being burned, the earth will soon run out. The future of energy will instead look to renewable sources of energy that do not pollute or release greenhouse gases. Renewable alternative energy sources are already in use to some degree. Biofuels like ethanol and biodiesel are already being produced and used in the United States and many other countries. The same is true of wind power and solar power, but these two energy sources are not yet very dependable or cost effective. From the ocean, wave power and current power are other alternative sources of energy that do not put a strain on the earth, and so is geothermal power. These technologies are still in initial research phases though, so results won’t be known for a while. It is important that these energy sources are fully developed because the future of energy may not rely on one source but many combined. Biomass energy is one alternative and a renewable energy source that shows great promise. This energy is produced using organic matter such as plant and animal waste and materials. Biofuels are one type of biomass energy and this energy can also be used to produce heat, electricity, and light. Critics say that biofuels are not acceptable because they are produced in this country using corn (ethanol) and soybeans (biodiesel). This causes skeptics to blame food shortages and higher food prices on the production of biofuels, though this is not true. Biofuels can be made from any organic material. Switchgrass and willow can be used instead of crops that use fertile land and are considered food crops. The Castor plant can be used to create biodiesel instead of soybeans, and Castor plants can grow in very poor soil that is not suitable for food farming. Biomass energy can create energy out of household and municipal solid waste, including food scraps, leaves and other organic yard debris, and many other things that fill and clutter our landfills and garbage dumps.

With such issues like global warming, air pollution, and other environmental problems that have resulted somewhat from using fossil fuels to create energy, the future must include the use of clean burning fuels instead of fossil fuels. Biomass energy can be implemented on a very large scale with almost no modifications and this is a much cleaner burning fuel source comparing to fossil fuels. Investing in renewable alternative sources of energy now means that in 10 or 20 years, dependence on foreign oil and fossil fuels will no longer be a problem. There is also wind farms that create so much energy that excess is sold to power companies and there are homes that use solar energy in combination with other traditional energy sources. Cars have been created that can run on gasoline blends that burn up to 85 percent ethanol mixed with 15 percent gasoline. Vehicles that burn this fuel blend are called flexible fuel vehicles and are very friendly to the environment and a tight budget. Surely, energy in the future will see a lot more biomass energy production, biofuels being used exclusively, and alternative energy sources becoming common and standard.

What is geothermal power? We have all probably heard about this before, but most of us do not understand what it means or how geothermal power can help combat global warming and renewable energy needs. The word geothermal comes from the Greek words for earth and heat. This energy is created from heat inside the earth. Geothermal energy is renewable and does not create harmful emissions like fossil fuels produce. The source of geothermal energy is water, which is heated up or turned into steam by the heat inside the earth. This energy can then be used to generate electricity and heat buildings instead of using natural gas or coal.

Geothermal energy comes from the core of the earth, and this source is approximately 4,000 miles below the crust of the earth’s surface. All rock contains some radioactive particles, and as these particles slowly decay in the core of the earth, they can produce heat that is hotter than the surface of the sun.

The core of the earth is divided into two distinct layers: a solid layer and a molten rock layer called magma. The mantle is the next layer and is around 1,800 miles thick. The mantle completely surrounds the outer core. The last layer is the crust, which encompasses the sea floors and the land on which we walk. The crust of the earth is divided into plates and there are spaces or gaps between these plates. In the spaces between the plates, liquid rock or magma can come up to the surface of the crust. This results in a volcano. The deeper you go into the earth, the higher the temperature becomes because water and rocks are absorbing heat from the magma. Continue Reading »
