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.

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.

Coal If you turn on your lights you are using electricity. Electricity comes from coal . These are the steps of how coal is converted into

electricity. It is dug up from mines and carried in dump trucks. Then the coal is carried to a company which grinds

the coal into powder. The powder is mixed with hot air.

This step makes the coal burn more efficiently. Then the coal is moved to the furnace.

The coal heats water which turns the water into steam. A turbine is spun by the heat energy.

Then the turbine spins a copper coil that is on a generator. This creates electricity.

Coal is used 21% of ways to make electricity.

Quick Facts Coal is a sedimentary rock. Black Thunder Mine is the largest surface mine. The United States produces about 20%, or 1.1 billion tons, of

the world's coal supply—second only to China. Coal generates about half the electricity in the U.S.A The U.S.A has a 245 years worth of coal. Wyoming is the top coal producing state it produced 400 million

tons in 2004. The U.S.A has produced 15 billion tons each year for the past 15

years. The value of coal mined in PA in 2005 was $6,270,000,000. The U.S. is the leader in known coal reserves. The U.S. produces 1.1 billion tons that’s a value of $20 billion

dollars. Here are where some of the major coal deposits, Illinois,

Wyoming, Kentucky, West Virginia, Pennsylvania, Ohio, Colorado, Texas, and Indiana.

Dangers of Coal MiningThere 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.
