Throughout the years electricity has become a source of energy that cannot seem to be replaced; however there are many different alternatives to this source of energy. One specific alternative is geothermal energy, which might be just as effective as electricity, but much less harmful to the environment. Electricity, although very helpful, produces fuels that might be harming not only our world, but our human society. To power electricity we must use fossil fuels such as coal, oil, and natural gas. An electrical current is produced because of the attraction between the protons and the electrons. As the electron moves around the atom’s nucleus it forms an electrical current. Electricity is powered by the fossil fuels that are non-renewable, so therefore they are very limited. They also produce carbon dioxide, which is affecting our air pollution, according to BBC news, coal and oil produce sulfur dioxide that might lead to acid rain. Therefore, geothermal energy is a great alternative because it does not produce as much pollution as electricity does; this is according to the article Advantages of Geothermal Energy, from Conserve Energy Future.
According to the Union of Concerned Scientists, the geothermal energy is obtained from the world’s center core. This source has been used throughout the world, and has helped reduce the usage of fossil fuels. Geothermal energy is renewable because the heat in the earth is constantly being produced; however, if the energy is converted into a solid, it can no longer be used. Geothermal energy is captured from the center of the earth. As the heat flows to the surface, it is converted into steam and hot water. There are three types of geothermal power plants: dry steam, flash steam, and binary ...

  • Fossil Fuels Essay

    952 Words  | 2 Pages

    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

    ...Kroeker designed the first commercial geothermal heat pump to heat the Commonwealth Building in Portland, Oregon and demonstrated it in 1946. In 1960, Pacific Gas and Electric began operation of the first successful geothermal electric power plant in the United States at The Geysers in California. The original turbine lasted for more than 30 years and produced 11 MW net power. The binary cycle power plant was first demonstrated in 1967 in the U.S.S.R. and later introduced to the U.S. in 1981. This technology allows the generation of electricity from much lower temperature resources than previously. (Wikipedia, 2011)

  • Geothermal Plants In Texas

    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

    Some climate scientists such as Ken Caldeira believe that humans will never reduce greenhouse gas emissions and that the earth will eventually return to the climate of the Cretaceous period due to climate change (How Far Can Climate Change Go?, 2012). There is enough evidence to suggest that this will not happen. Thanks to our individual senses of environmental consciousness, our uses and further research of alternative energy sources and fuels, and the potential for space colonization and exploration. We still have a chance to reverse our impact on the planet because of further advancements in technology and a sense of global consciousness.

  • Hydrothermal Vents

    548 Words  | 2 Pages

    Hydrothermal vents are among the most diverse and biologically active ecosystems of the ocean. At these locations, seawater penetrates through the cracks in the crust until it reaches hot heated magma rock. The seawater is heated and converted into hydrothermal fluid. These hydrothermal fluids then rapidly diffuse through the seafloor as black jets of superheated fluid or water rising from cracks in the deep ocean seafloor. This interaction between superheated hot hydrothermal fluid from the crust and seawater supports microbial life that is independent of photosynthesis and is detached from the photosynthetic biosphere. “This microbial life alters the chemistry of hydrothermal vent habitats and provides nourishment for the vent fauna” (Holden 206).

    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 of the most compelling arguments for the use of renewable energy is how many forms exist of it. Nuclear power, solar power, wind power, tidal power, hydroelectric power, pumped storage, wave power, geothermal power, biomass, and biogas are the most widely known renewable energy sources (Darvill, 2013). This large selection of fuels supports the idea of renewable fuels one day powering the entire planet. All the sources of energy have different niches and benefits. Solar energy is extremely effective when providing energy for small establishments such as a house or small store, but hydrothermal power would be a more plausible solution for factories or large establishments....
