Renewable And Nonrenewable Resources Essay

1388 words - 6 pages

In our environment, there are many concerns on how to make the world a better place to live. One of the biggest issues is our energy and power resources. Green energy is renewable energy that is environmental friendly, and forms of green energy include geothermal, hydropower, solar, and wind energy. Nonrenewable resources, as the name implies, are resources for which there is a limited supply, and forms of nonrenewable resources include fossil fuels and nuclear energy. Much of our world is using fossil fuels, but in the process of achieving everyday needs, we are destroying our environment. In my opinion, people should cut down on the usage of fossil fuels and depend more on green energy. ...view middle of the document...

Lignite has the lowest amount of carbon, which means it holds the lowest energy content. Bituminous is in between anthracite and lignite in terms of carbon content. Coal gets extracted from the ground through vertical and horizontal shafts; coal miners then travel underground to dig out the coal. Coal is primarily used to power factories and other power plants (Fossil Fuels - Coal, Oil and Natural Gas, Sec. 2).
Oil is found between folds of rock deep below the earth. People drill the earth to reach the deposits where the oil is stored. Oil is extracted from the ground through seeps where oil leaks up from the ground. Oil was used as medicine in ancient times, but more as fuel. Oil gets reformed to produce petroleum. Before petroleum was discovered, people used whale oil, which was considered very expensive, as fuel. Much of the oil used by the United States comes from the Middle East (Fossil Fuels - Coal, Oil and Natural Gas, Sec.3).
Natural Gas is extracted by drilling into the earth. Pipelines are used to send the gas to a storage area. Natural Gas, believe it or not, is lighter than air because it is mainly made up of methane. Methane has one carbon and four atoms of hydrogen; it is extremely flammable. Natural gas does not have odor and it cannot be seen by the naked eye. People mix it with a certain chemical which makes it have a strong odor similar to rotten eggs. The odor is used to help spot leaks (Fossil Fuels - Coal, Oil and Natural Gas, Sec. 5).
Nuclear energy is a nonrenewable resource that uses uranium atoms to power electricity. Uranium atoms getting split is known as the fission process. The fission process generates steam, and the steam is used by a turbine to generate electricity. It costs just as much as fossil fuels, and nuclear energy is reliable. Nuclear power can be used to generate electricity to homes, and supplies to various nuclear submarines (Nuclear Power, Sec. 2).
Renewable resources are resources that can be replenished in an adequate amount of time. Renewable resources are environmental friendly, but more expensive than nonrenewable resources. Thus, only 8 percent of energy from the United States is used from renewable resources. Nonrenewable resources are expected to be of shortage in the next sixty years; therefore, it would be wise to consider using renewable resources as the primary source of energy (Wieman, Par. 1).
Geothermal energy is energy that is renewable and derived from the earth’s internal heat. This heat is taken from well below the earth where melted magma can be found. To produce geothermal energy, one must drill the reservoirs to reach hot water and steam. The steam drives the turbines and the turning of turbines produces electricity. Geothermal energy is available all year long, and relatively inexpensive. “Geothermal fields produce only about one-sixth of the carbon dioxide that a relatively clean natural-gas-fueled power plant produces” (Tapping the Earth's Heat, par. 8).
Hydropower is...
