It is common knowledge that the quest for a better, infinite energy resource is consistently being searched for. The simple answer in solving the energy crisis is to utilize the heat from the Earth we live on. Geothermal energy harnessed from magma will produce enough energy to power the world. Geothermal energy is already one of the most effective and environmental friendly sources of power that is used today (Introduction to Geothermal Energy). Though most of the geothermal energy is harnessed from hot springs (Geothermal Basics – Basics), harnessing the energy from magma will create three times as much power (Melting Points of Rocks). To begin, what exactly is geothermal energy and how is it beneficial to the world?
Geothermal energy is the power produced from geysers and hot springs (Geothermal Energy Geothermal Energy). Magma is located closer to the surface where water is produced and it heats and boils the water (Geothermal Energy). It is difficult to locate these hot springs because they are deep beneath the Earth’s surface. The places where these reservoirs are found are mainly in the Western United States. To be able to produce electricity efficiently, these reservoirs must reach temperatures of 102oC and up (Geothermal Energy Geothermal Energy).
Harnessing this energy is easier said than done. The most effective way to harness energy is dry steam reservoirs. A well is drilled into the ground about 10,000 feet deep and steam is directly piped to a turbine generator. The generator produces the energy needed and the steam becomes condensed and cooled back into water. Once the water is reproduced, it can be injected back into the thermal reservoir well and be used to create more steam in a water cycle-like reaction (Geot...

Hawaii’s geography is optimal to make use of biofuel, solar, and geothermal resources (Brown et al. 2008, 27). The focus of this paper will concentrate on three alternative energy solutions: 1. Biofuels, 2. Solar Power, and 3. Geothermal. Biofuels will be broken down into biomass, ethanol and biodiesel. Solar energy will be divided into solar power plants, residential solar and passive solar systems. Geothermal energy is constituted of geothermal power plants, geothermal water heating and heat pumps.
In order to full under stand geothermal heating and cooling you first need to understand what geothermal energy is. Geothermal energy is a form of energy conversion that is provided by nature and that can be used by humans to cook, bath, heating and generate electric power. The energy is created by capturing and harnessing the heat energy. This heat is formed underground and is created by the radioactive decay of certain elements such as potassium, thorium, and uranium in Earth. One way to produce energy from geothermal heat is to use the heat to create steam to drive turbines that spin an electric generator, this method and others like it can create about 1,400,000 terawatt-years roughly three times the world’s annual consumption(Lund 2014).
One form of alternative energy is called geothermal energy. Geothermal energy is thermal energy that is created and stored beneath earth’s crust. The most recognizable form of geothermal to most people would be in the form of a hot spring. Heat from Earth’s core heats rock and water differently; some spots can reach up to 700 degrees, whereas some receive not much heat at all. Steam from the water that receives the most heat is trapped in porous rocks underground. This is called a geothermal reservoir. Geothermal energy is very useful because it is renewable, and limitless. Heat continuously flows from the earth’s core, and continues to heat the water and produce steam. Geothermal is also useful because it is 80 percent cheaper than fossil fuels, and it requires no fuel. In fact, the use of geothermal energy decreases the independence on fossil fuels greatly. Geothermal energy does not produce pollution and could potentially save millions of dollars per year if used to replace fossil
One of the big stalls on geothermal plants in Texas has been the fact that in order to get to a source hot enough you would have to dig deep in order to hit a site. We are proposing that we use existing drilling sites in the Permian Basin that have been used up and no longer needed for oil. If we can find the deepest sites with the highest temperatures we can use that and continue drilling deeper if needed. This would make these sites more economical as well since it does not need to be closed up. This way the need to find a geyser would not be needed since there is energy that exists. Setting up the plant is not much different from a normal coal power plant. The advantage is that it uses energy from heat from the earth which also give it more
Geothermal is energy produced from the heat of the earths core. It is a natural resource that is very plentiful. Heat contained in the earth is so intense it creates molten magma. There are different types of geothermal energy. Some are formed with magma near the earth’s surface and heats groundwater. The steam from this is turned into geothermal energy, which is electricity produced from the steam of the water.
Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. Due to this effect, it widely impact lives and cultures around its area. During winter, temperatures of the whole Yellowstone will drop to 0 degree Fahrenheit, and the snow thickness reaches 20 inches. In addition, an elevation of 7,733 feet (2,357 m) above sea level forms rarefied air in Yellowstone area. All of these show a severe circumstance for any plants or animals. However, geothermal energy in Yellowstone changes this condition.
Most of the geothermal heat does not bubble out as magma, water of steam, but instead, it is stored in the mantle, collecting as pockets of heat. By drilling and pumping down water to create steam, this energy can be harnessed.
Geothermal energy is the thermal (heat) energy within the planet. Its is considered a renewable source of energy as it has always been around for for an abundant amount of years it will probably still be used in the next years because its source is the almost unlimited amount of heat generated by the Earth's core. Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be injected, making it a sustainable energy
Many people support the idea of alternative energy, yet there is no move to implement it as a viable alternative to fossil fuels. It is the burning process that makes fossil fuels so bad for the environment. An alternative source that does not require combustion is necessary to avert the process of global warming. Wind power and hydroelectric power both turn t...
For the generation of electricity, hot water, at temperatures ranging from about 700 degrees F, is brought from the underground reservoir to the surface through production wells, and is flashed to steam in special vessels by release of pressure. The steam is separated from the liquid and fed to a turbine engine, which turns a generator. In turn, the generator produces electricity. Spent geothermal fluid is injected back into peripheral parts of the reservoir to help maintain reservoir pressure. If the reservoir is to be used for direct-heat application, the geothermal water is usually fed to a heat exchanger before being injected back into the earth. Heated domestic water from the output side of the heat exchanger is used for home heating, greenhouse heating, vegetable drying and a wide variety of other uses.
In same places such as Iceland, hot water comes naturally to the surface as steam, which can drive turbines to generate electricity, Some power stations make use of lava that flows from the volcanos. Despite of few disadvantages, it is an undeniable fact that geothermal energy is an extremely valuable, simple and clean source of energy that can benefit mankind in a big way.

During the 21st century our country and our planet as a whole is in energy crisis. We have used too many oils and fossil fuel that our non-renewable resources are running out. Oil is limited and is at outrageous prices, this result is making our economy suffering. With fossil fuel and oil as the main source of energy the people of this planet need to start looking for an alternative energy source because our fossil fuel will not last forever and fossil fuel also polluted our planet. This is where a renewable energy comes in. I will start talking about one of the oldest renewable energy know to man, one of the many renewable energy we have today are Geothermal Energy. Geothermal energy is one of the many different ways we can preserve our fossil fuel. It is one of the oldest energy resources out there. During the ancient time, the people back then uses geothermal energy in form of hot water from the nearby hot springs. They used the hot water, to bathe, heat their home and also produce electricity. The first industrial uses for geothermal energy occur near Italy in the 18th century, according to (Geothermal Energy History, 2014). In 1904, Italian scientist Piero Ginori Conti invented the first geothermal electric power plant in which steam was used to generate the power, according (Geothermal Energy History, 2014). Geothermal Energy is also better for the environment because it does not involve burning and polluting our ozone layer. You may ask what is geothermal energy? The definition of geothermal energy derived from its name. Geo means earth and thermal means heat, so geothermal is earth’s natural heat. Geothermal energy uses the earth heat and by adding rain, you have created steam. The steams are then creating heat and electri...
Over the past decades, geologists and scientists alike have determined that the Earth is running out of non-renewable resources, particularly those resources that provide us with energy that fuels our world’s economies, jobs, and most importantly our daily lives. Without this energy, whole countries can collapse, and the human race would struggle to survive. Therefore, it is safe to assume that we as a nation are entirely dependent on energy, or the ability to do work (Gale Science in Context). Consequently, we are now actively searching for more cost efficient and useful forms of energy to replace those we currently use. By doing this we will be helping the earth by reducing carbon emissions and cutting down on air and water pollutants. This may ultimately prolong the life of our planet, and save money and resources while doing so.
Nowadays fossil fuels are classed as unsustainable due to the possibility of them running out in the near future and that the waste produced by them, greenhouse gases, cannot be absorbed by nature. The way forward for future generations is sustainable energy which has had recent advancements like: solar power, hydroelectric, geothermal. These are all ...
