Coal

  1. 1. Coal<br />Written by Christian Schilling <br />Press right arrow key to continue.<br />
  2. 2. What is<br />
  3. 3. is the ability to do work!<br />
  4. 4. Over time different ways of creating energy have been discovered. These ways are a lot more complex it effects the environment a lot. Some of the ways that have been developed over time are Biomass, Wind, Geothermal, and Hydropower. These ways are not only a lot better for the environment but more efficient. <br />Coal covers about 21% of energy consumption. Even though it isn't the smart choice it will still keep our cities running until the next 25+ years.<br />
  5. 5. Coal<br /> If you turn on your lights you are using electricity.<br /> Electricity comes from coal .<br /> These are the steps of how coal is converted into electricity.<br /> It is dug up from mines and carried in dump trucks.<br /> Then the coal is carried to a company which grinds the coal into powder. The powder is mixed with hot air.<br /> This step makes the coal burn more efficiently. Then the coal is moved to the furnace.<br /> The coal heats water which turns the water into steam. A turbine is spun by the heat energy.<br /> Then the turbine spins a copper coil that is on a generator. This creates electricity.<br />
  6. 6. Coal is the third most used resource<br />Coal is used 21% of ways to make electricity.<br />
  7. 7. Quick Facts<br />Coal is a sedimentary rock.<br />Black Thunder Mine is the largest surface mine.<br />The United States produces about 20%, or 1.1 billion tons, of the world's coal supply—second only to China.<br />Coal generates about half the electricity in the U.S.A<br />The U.S.A has a 245 years worth of coal.<br />Wyoming is the top coal producing state it produced 400 million tons in 2004.<br />The U.S.A has produced 15 billion tons each year for the past 15 years.<br />The value of coal mined in PA in 2005 was $6,270,000,000.<br />The U.S. is the leader in known coal reserves.<br />The U.S. produces 1.1 billion tons that’s a value of $20 billion dollars.<br />Here are where some of the major coal deposits, Illinois, Wyoming, Kentucky, West Virginia, Pennsylvania, Ohio, Colorado, Texas, and Indiana.<br />
  8. 8. Dangers of Coal Mining<br />There are many precautions coal miners have. They where a special device that detects poisonous gases that can harm humans. They used canaries to detect gases if the canary died that meant you got to get out of that mine. <br />
