Kevin Kim Professor Moyer Todd Morrison Geothermal Energy Zeno, a Greek philosopher, made this statement based on human interaction with nature: “The goal of life is living in agreement with nature.” The amount of punishment Earth has taken from humans is monumental. Likewise, we can expect things to get worse every year, well at least according to studies. The need for alternative energy is an issue in this world that needs to be addressed more. Not only is oil, our main energy source, tainting every aspect of this world--from ocean to land to air, but is very close to being used-up. However, even when we are being forced to discover a different source for energy, many countries still look to depend on oil for much longer. Geothermal energy, a renewable energy source, is a resource in which heat from Earth can deliver electricity for humans; not only a great idea, but also very worthy of giving a serious run at due to manageable costs. The consequences we face from our present energy source jeopardize Earth in many ways. Almost every car in this world runs on oil; air pollution from cars play a big role in further exacerbating our environment. Humans also face dilemmas arising from car pollution. The increasing rate of babies being born with respiratory problems can be blamed on car pollution. Environmentally, occurrences such as global warming and ozone layer growth are direct outcomes of automobile pollution. Not to

mention, animals that coexist with humans are affected as well. The need for a different source of energy is very blatant and urgent. Time and resources are running out fast; everyone must look to improve upon our imposed situation. Depending on geothermal energy in our near future is something to look at. The word geothermal is derived from two Greek words: geo , meaning Earth, and therme , meaning heat. When combined, geothermal literally means Earth heat. Basically, geothermal energy is a resource derived from Earth’s inner heat. The inner- core, which is composed primarily of a nickel-iron alloy, holds tremendous heat that can be transformed into energy for daily use. Once this method is consummated, there is not much we cannot do with geothermal energy that we could do with oil. Experts tend to agree that this form of alternative energy is highly dependable, because as long as planet Earth still remains in tact, so will geothermal energy. The energy is stored in a very safe place, given that Earth’s inner-core is approximately 3,200 to 4,000 miles beneath surface. Furthermore, there is no such thing as overusing geothermal power because naturally, Earth constantly makes heat. Geothermal energy, which comes from mining Earth’s heat, is efficient in a place where there is high temperature ground water at shallow depths. Wells are drilled into fractures in a basement rock. Then, hot water or steam flows up the drilled passageway through either pumping or flashing flow. Another method, though in an
