  1. Fossil Fuels By Katie Morgan and Paige Ronan

  2. Where Fossil Fuels Come From • All energy in oil, gas, and coal originally came from the sun. • Ancient plants captured the energy we burn from the sun. • Take millions of years to form • Not renewable within human lifespan • Releases carbon dioxide • Overwhelming natural cycles • http://www.techalive.mtu.edu/meec/module19/Page4.htm

  3. The Process of How Fossil Fuels Form • Formed through animals and plants being buried in sediment on land • Major contributor is plant life that has decayed • Coal is formed from trees • The plants and animals that made fossil fuels lived up to 300 million years ago.

  4. Environmental Impact • Greenhouse effect • Acidic pollution increases the chance of asthma and other respiratory diseases • Damages trees and buildings • Creates dead lakes

  5. Advantages • Inexpensive(coal)‏ • Easy to recover in U.S and Russia • Easy to obtain • Good distribution system • Better as space heating energy source

  6. Disadvantages • Requires expensive air pollution controls • Large price swings with supply and demand • Expensive for energy generation • Major contributor to global warming • Limited availability

  7. Four Outputs • Type 1: Expected Desired- Generates Electricity • Type 2: Expected Undesired- Produces undesired smoke and ash • Type 3: Unexpected Desired- Waste energy production • Type 4: Unexpected Undesired- Dead lakes and regions from acid rain

  8. Facts • Three types of fossil fuels are coal, oil, and natural gas. • Fossil Fuels are made by fossilized remains of dead plants/animals. • Fossil fuels are hydrocarbons found in the top layer of the earth's crust. • Non-renewable • Sulfur dioxide is a key contributor to acid rain, mostly in the northeast U.S. • Nitrogen oxide contributes to acid rain and smog • Carbon dioxide is a greenhouse gas, trapping heat into the earth's atmosphere. • The age fossil fuels were formed is called the Carboniferous Period.

  9. Facts continued • The U.S. Uses about 20.8 million barrels of oil a day. • Fossil fuels account for nearly 80% of our country's energy. • The earliest known use of coal was in China. • Oil has been used for more than 5-6 thousand years. • Coal could be found even during the time of the dinosaurs.
