This is my essay on fossil fuels. Can This is my essay on fossil fuels. Can someone please check to see if there are any improvements that can be made? Also, I need help writing a conclusion.

Have you ever thought about where your electricity comes from? What the petroleum your car runs on is made of? What produces all the energy you see?

Oil, coal, and natural gas are collectively known as fossil fuels. Today, eighty-five percent of all energy produced in the United States comes from burning these fuels. That energy powers almost two-thirds of our electricity and all of our transportation. We are currently in a crisis because fossil fuels are non-renewable; once they are gone, they are gone. To serve the end of fossil fuels, the world needs to find and develop alternative fuel sources.

Coal is a solid fossil fuel formed over millions of years by decay of land vegetation. When layers are compacted and heated over time, deposits turn into coal. Oil is a liquid fossil fuel that is formed from the remains of marine microorganisms deposited on the sea floor. After millions of years the deposits end up in rock and sediment where oil is trapped in small places. Natural gas is a gaseous fossil fuel that is versatile and abundant. Like oil, it is formed from the remains of marine microorganisms.

The biological impacts as a result of the use of fossil fuels can harm the living organisms in the area. Oil spills and air pollution, which are also an environmental impact, can harm farm crops, rain forest plants, insects, animals, and even humans.

Combustion of fossil fuels is considered to be the largest contributing factor to the release of greenhouse gases in the atmosphere. There are many types of harmful outcomes which result from the process of converting fossil fuels to energy. Some of these include air and water pollution and accumulation of solid wastes. When coal is burned, it releases nitrous oxide which is kept in the atmosphere for a very long time. The harmful impact of this chemical could take up to a couple of hundred years to make itself known. Converting fossil fuels may also result in accumulation of solid waste. This type of accumulation has a devastating impact on the environment. It also increases the risk of toxic runoff which can poison surface and groundwater sources for many miles. Toxic runoff also endangers surrounding vegetation, wildlife, and marine life.

To reduce our society’s dependence on fossil fuels, we can use some alternative renewable sources of energy like nuclear fusion. Fusion involves the extraction of hydrogen from water and the combination of two hydrogen atoms to form helium. Another source is hydrogen. Most schemes for generating hydrogen are based on the splitting of water using solar energy directly. Hydrogen can substitute natural gas. The last source we can use is energy plants. Active improvements in bioengineering may provide the basis for enhancing the efficiency or redirecting the end products of photosynthetic processes to produce commercial fuels such as hydrogen.

There are new innovations in technology that are currently being explored and implemented to help reduce our dependence on fossil fuels. For example, concepts for combining end uses and supply generation facilities to better utilize waste heat are already being employed. These include cogeneration of steam, electricity, and district heating. Future combinations may include the use of nuclear energy to generate heat for coal gasification. With these options we can help phase out our dependency on fossil fuels and find clean and useful sources of power.

There are both pros and cons of alternative fuel sources. For example, one advantage of geothermal energy is that it’s safe. It’s also clean, very cheap, and efficient. The cons are that it may cause small after-shock earthquakes and minor damage may take a hundred years to recover. The pros of wind energy are that its completely clean and healthy for the environment and wind energy is completely renewable. One con of wind energy is that wind farms are an eyesore according to some people. The pros of solar energy are that it’s a renewable resource, it doesn’t give off any harmful substances, and sunlight is always free. The cons are that not every location is a feasible site for solar and the initial costs for components can be high. The bottom line is that every alternative fuel has its pros and cons, so even if they’re not perfect, they can still be used.

Thanks

  1. A con on geothermal power is that usually the hot water/steam coming up is highly corrosive, and are very costly to run through turbines, as the turbine blades suffer badly. Replacing those blades is a costly maintenance nightmare.

    You bottom line is a whimpy conclusion. To me, alternative energy should be measured on a rubric of cost vs benefits, but this is seldom done: politics play large parts in approving and financing silly projects.

    I would recommend a conclusion that says we ought to evaluate each project based on lifetime costs and benefits, including environmental costs. Everyone will agree with that, but not do it in the real world.

  3. Right.

    So ... what are the MAIN POINTS you're using to prove your thesis statement?

    To serve (?) the end of fossil fuels, the world needs to find and develop alternative fuel sources ...
    (How will you finish this sentence?)

  5. OK, now, just thinking about your first paragraph -- and your instructions --
    -A clear thesis statement that expresses the argument, goals, and/or main focus of the paper; thesis statement should be easily recognizable
    -Introduces topic with general background information and outlines a road map with development of supporting ideas; provides an overview of what the reader can expect to learn
    -Effectively grabs readers' attention and makes them want to continue reading

    I see your thesis statement (but do you mean "serve" or "survive"?), but I don't see the second and third elements your teacher expects to be included in this paragraph. How can you fix this?

  6. @bobpursley thanks, but I don't really understand what you're saying...what should I include in my conclusion?

    @writeacher thanks. I don't know how to include the second thing in there [Introduces topic with general background information and outlines a road map with development of supporting ideas; provides an overview of what the reader can expect to learn] And about the beginning, that's the best I could do. I thought that would grab the readers' attentions...

  7. Re the second item in your instructions for the introduction (... roadmap):
    http://leo.stcloudstate.edu/acadwrite/thesistatement.html

    Read the fifth one here (next to last).
    Hemingway's stories helped create a new prose style by employing extensive dialogue, shorter sentences, and strong Anglo-Saxon words.
    This states the overall thesis (underlined) and then tells us the three main points that will be explained in the paper. What are those three main points?

  10. You're having trouble coming up with what your three main points are, right? I'm sure that's because I don't think you planned ahead and put an outline together before you started writing. If you had an outline or plan, you'd be able to list those three points right away ... bing, bing, bing.

    Your paper is very disjointed. That's how I can also tell you didn't start from a plan or outline. One obvious thing I noticed is that your 3rd "paragraph" is not only not a fully developed paragraph, but it's also out of place.
