Geothermal Energy: A Solution to the Energy Crisis
Abstract
So far, scientists have not found a successful substitute for fossil fuels that can handle both the large demand for energy and solve the global warming problem. I propose that geothermal energy is a clean, widely available, and renewable alternative to the usage of fossil fuels. In this paper, I will explain how use of geothermal resources can be energy-efficient, environmentally clean, and cost-effective. I believe that the US government should increase funding for geothermal energy research. This may be the solution to our present energy crisis and global warming.
Introduction
There is a call of action to solve today’s energy crisis. What we need urgently is a clean, abundant, and reliable source of energy. Geothermal energy may be the solution. Geothermal energy does not produce CO2 and is inexpensive compared to the unbelievably high gas prices. This type of energy is also renewable so it can continue to feed the growing population of the world. “New [geothermal] facilities can produce electricity for being between 4.5 and 7.3 cents per kilowatt-hour, making it competitive with new conventional fossil fuel-fired power plants.” (Union of Concerned Scientists, 2) This shows that if there is more research focused onto this topic, geothermal energy may become the solution to our energy crisis.
Current Energy Consumption
Currently, the energy consumption has been increasing exponentially. Energy consumption increases by 2% each year causing a doubling in only 35 years. As of 2003, the
energy consumptions in quadrillion BTU (British Thermal Unit= 1055.06 Joules) are: North America- 118.3, Europe- 127.4, Asia- 120.2, Middle East- 19.6, Central/South America- 21.9, ...

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.
Based on Laurel Nesbit, a program assistant in the Office of Sustainability here at UF, our campus manages to utilize 470,000 Megawatts of energy annually. This figure is generated from all the energy-consuming gadgets that operate on our campus on a daily bases. These gadgets include computers that are left turned on over the night even they are not in use, copiers, and the fume hoods in our laboratories. Admittedly, the success and the health of wellbeing of the students is contingent upon some of these equipment. For instance, the laboratories need the fume hoods in order to keep the experimenters safe. Instead of casting these necessities away, we can develop alternatives which will be capable of generating energy in order to compensate for the electricity that we endlessly
The greatest impact on reducing dependence on fossil fuels could begin at home. All around us are devices that consume energy even as we do nothing with them. Known colloquially as “vampire power”, these devices in standby power mode continue to consume energy as they are never actually “off”. Studies by Ross and Meier (2001) have shown that the average household can have up to 40 different devices consuming energy, from clocks to microwaves and DVD players to television, these devices add up to, between, 5% and 26% of the total electricity consumption in a household – energy likely produced at the cost of burning fossil fuels, both in production of the electricity and the transportation of the fuels themselves.
Geothermal energy is one of the oldest sources of energy. It is simply using and reusing (reusable energy) heat from the inside of the earth. Most of the geothermal energy comes from magma, molten or partially molten rock. Which is why most geothermal resources come from regions where there are active volcanoes. Hot springs, geysers, pools of boiling mud, and fumaroles are the most easily exploited sources. The ancient Romans used hot springs to heat baths and homes, and similar uses are still found in Iceland, Turkey, and Japan. The true source of geothermal energy is believed to come from radioactive decay occurring deep within the earth.
When picking an energy resource for the topic of this paper, I bounced around a lot of ideas. Then it occurred to me that I should write about what I will be living with in about a month. My mom just finished designing and building our earthbag, solar, off-grid house, a four-year endeavor. I will soon live in a place powered by one of the most common alternative energy resources, solar energy, so I should learn more about it. At our new house, we have two stand alone pedestals with six 170W panels on each pedestal, making for a 2040W or 2kW solar system.
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....
In the search for alternatives to fossil fuels, scientists and policy makers have focused on three options: nuclear power, energy from biomass; and a combination of wind, water, and solar power. Nuclear power, however, is much more costly and runs the risk of having it fall into the wrong hands where it could be turned into a weapon of mass destruction. The third option entails wind turbines, photovoltaic power plants and rooftop systems, concentrated solar thermal power plants,...
Nowadays, it's important put the focus on how you can save energy and ways to do this cheap. It's true that people maybe have another issues to care but in fact energy cannot be replaced so the most important now is think forward and find solutions.
Household energy conservation is a very practical and realistic approach to conserving energy within our society. US households consume a tremendous amount of natural gas as well as electric energy. It has been calculated that the amount of energy consumed within the US increased exponentially from about 1850 to 1975. If energy continued to increase at this rate, we would be experiencing severe energy shortages in our current society. Luckily, steps towards conservation, including various energy regulations, have curbed that growth somewhat, brining the predicted 160 Qbtu/yr for the year 2000 down to around 93.8 Qbtu/yr by the year 1996. However, household energy usage is still a major issue as households consume about 38% of the total consumed energy and contribute greatly to natural gas consumption and issues such as global warming. Therefore, it is important that people understand how we use energy in the household and what steps can be taken to conserve that energy.

inferred for the reservoir (4). The magma ascent to the surface occurred through a conduit of possibly 70 to 100 m in diameter (5). A thermal model predicts that such a reservoir should contain a core of partially molten magma (6) that can be detected by high-resolution seismic tomography.
Using fossil fuels such as coal and oil is inefficient, dangerous, and otherwise a process that is known to eventually fail as a long lasting energy source. Yet, there is hope for the future of energy, this new hope has many shapes and forms, but requires a chance to be fully implemented in our everyday life. Such energy sources like solar energy, wind energy, geothermal energy, and hydro power are the key to our future. These energy sources are proven to be long lasting, safe, more reliable, and the next innovation. In short, all Americans should switch to renewable energy, resulting in a safer and more efficient world.
