Compare and contrast the various sources of energy.

---my teacher told me to do renewable and non-renewable.

this is what i got:

Energy sources are of two types: nonrenewable and renewable. Energy sources are considered nonrenewable if they cannot be replenished in a short period of time. On the other hand, renewable energy sources such as solar and wind can be replenished naturally in a short period of time.
One non-renewable source found in the world today is coal. Coal is a combustible black or brownish-black sedimentary rock composed mostly of carbon and hydrocarbons. It is the most abundant fossil fuel produced in the United States.
Coal is a nonrenewable energy source because it takes millions of years to create. The energy in coal comes from the energy stored by plants that lived hundreds of millions of years ago, when the Earth was partly covered with swampy forests.
Almost 93% of the coal used in the United States is used for generating electricity. Except for a small amount of exports, the rest of the coal is used as a basic energy source in many industries including steel, cement, and paper. The major uses of coal are for electric power and for industry.

Another non-renewable resource is Oil (Petroleum). Oil was formed from the remains of animals and plants that lived millions of years ago in a marine environment before the dinosaurs. Over millions of years, the remains of these animals and plants were covered by layers of sand and silt. Heat and pressure from these layers helped the remains turn into what we today call crude oil. Crude oil is a smelly, yellow-to-black liquid .Other products made from petroleum include ink, crayons, bubble gum, dishwashing liquids, deodorant, eyeglasses, and tires.
Renewable energy sources can be replenished in a short period of time. One example of a renewable source is solar energy. Solar energy is the sun’s rays that reach the Earth. This energy can be converted into other forms of energy, such as heat and electricity. The advantage of solar energy is it can be used anywhere; disadvantages of using solar energy is there has to be sun around.
Wind energy is another renewable source. Today, wind energy is mainly used to generate electricity. Wind is a renewable energy source because the wind will blow as long as the sun shines.
Wind is a clean fuel; wind power plants produce no air or water pollution because no fuel is burned to generate electricity. Growing concern about emissions from fossil fuel generation, increased government support, and higher costs for fossil fuels (especially natural gas and coal) have helped wind power capacity in the United States grow substantially over the past 10 years. An environmental drawback to wind is their negative effect on wild bird populations and the visual impact on the landscape.

You need to have each source of information cited in TWO places:

A. the Works Cited page that is placed after the last page of your paper, and
B. in parentheses in the text of your paper, immediately after the quotation or paraphrase.

For example, this would go on the Works Cited page (with proper indentation for the second and following lines):

Du Bois, W.E.B. The Souls of Black Folk. Chicago, 1903. Project Bartleby. Ed. Steven van Leeuwen. Dec. 1995. Columbia U. 2 Dec. 2003
<www.cc.columbia.edu/acis/bartleby/dubois/>.

... and this would go immediately after the quotation or whatever:
(Du Bois)

The information in parentheses in the text needs to be as brief as possible. That's why there's a Works Cited page – for all the details of the listing.

------------------

In the website above, hold your cursor over the words CITING SOURCES in the left column and then click on whatever type of source you need help with. Many examples will show up. You will get two examples for each type of reference – one for the Works Cited page and one for the parenthetical (in-text) citation.

You can also see what a Works Cited page looks like – click on Sample Works Cited in the left column.

There's redundancy here:
Almost 93% of the coal used in the United States is used for generating electricity. Except for a small amount of exports, the rest of the coal is used as a basic energy source in many industries including steel, cement, and paper. The major uses of coal are for electric power and for industry.
How can you fix it?

I'm not reading more until you cite your source(s). Make sure there's no intentional or unintentional plagiarism.

Here's the website that should have been included above:
http://www.ccc.commnet.edu/mla/index.shtml

Use this for learning how to cite AND for making sure you know what plagiarism is and how NOT to commit plagiarism.
