1. Energy Expo Coal By: Julia, Carl, Roy, and Matt

2. Coal Non-renewable Coal is The worlds iron and steel industry depends on the use of coal 37% of the worlds generated electricity is produced from coal Coal is the cheapest source of fuel, averaging less than half the price of petroleum and natural gas. The value of coal produced in the US each year is nearly 20 million dollars. The federal receives more than 7 billion annually from the coal industry. State and local receive more than 9 billion each year in benefits. Coal provided the energy to fuel the industrial revolution. Coal is mostly carbon, hydrogen, and sulfur. There are four types of coal; lignite, subbituminous, bituminous, and anthracite.

3. History Coal provided the energy to fuel the industrial revolution. Coal has been used as an energy source for hundreds of years, and was part of trade, even during the time of the Roman Empire. The Native Americans used coal for cooking, making clay pots, and heating.

4. Where do we get it? http://science.discovery.com/videos/how-do- they-do-it-coal-mining.html http://science.discovery.com/videos/how-do- they-do-it-coal-mining.html It is made from the decomposition of long dead plants and animals. Coal is found in almost every country, and minable in more than 70 countries. Pittsburg has rich coal reserves.

5. How is it stored and released? You can find coal almost everywhere on earth, except the middle east. You recover coal by mining, either surface (or opencast) or underground (room and pillar, or longwall). You get the energy out of coal by burning it.

6. Coal is used to supply the fuel to produce electricity. Coal generates about half of the electricity used in the US. Texas uses the most coal out of all the states. Coal ash, a byproduct of the combustion, is normally used as a filler for tennis rackets, golf balls, and linoleum. On average, each person in the United States uses 3.8 tons per year. Coal production has produced by over 70 percent in the last 31 years. About 9% of US mined coal is exported to other countries. How is it used today?

7. Advantages and Disadvantages Advantages: a lot of stored energy Disadvantages: nonrenewable, limited suppy, polluting

8. Future? Each year 80% of green houses are produced by energy-related carbon dioxide emissions. The department of energy is spending 4 billion dollars on pursuing multiple demonstration projects for the deployment and storage of carbon capture. The demand for electricity continues to grow. Coal has enabled the electricity production to keep up with demand. If we continue to use coal at the same rate that we do today, we will have enough for between 215 and 300 more years.
