ASSAY: 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,…show more content…

In the flash steam approach, very hot water is used to power the turbines, it is collected in a tank in which the pressure is lowered enough to cause the liquid to form to steam. The third approach, binary steam, uses very high temperatures to heat another fluid, and then this fluid is transformed into steam, and begins to power the turbines. And the cycle converts the steam back to a fluid starting once again. In comparison to the usage of electricity, geothermal energy is renewable, does not pollute the air as much as electricity, no additional sources of fuel are needed to keep the power running, and once a power station is created it is very effective and not as expensive. The earth has been producing heat for billions of years and it seems as if it will keep producing many more to come. Some disadvantages are that a power plant can only be placed in a certain place, and in some cases the site where the station was built might run out of heat to convert to steam. Dangerous gases might escape from the earth’s center when making these power stations. In the other hand, electricity is producing a great amount of greenhouse gases that are affecting our environment. Also the prices for electricity are much more expensive in comparison to geothermal energy. The average price for electricity in the United States was 20.0 cents per kilowatt-hour in 2013 according to The Bureau of Labor Statistics, and according to University of Michigan
