11. United States of America – Coal Reserves

12. Fast Facts about Coal United States of America
The U.S. produces about 1.1 billion tons (20%) of the world's coal. China is second.
Coal deposits contain more energy than that of all the world's oil reserves.
Each person uses 3.8 tons of coal each year.

13. Coal and the Environment
Coal has a reputation as a dirty fuel source which pollutes the air and damages the landscape.
Coal suppliers are utilizing:
Land Reclamation
Reduction of Air Pollution 
No Scrubbers = More Pollution
Scrubbers= less pollution

14. Environmental Impacts of Burning Coal
Releases large quantities of CO2 into atmosphere = Greenhouse gas
Can cause Climate Change
Releases other pollutants into atmosphere = Mercury, sulfur oxides, nitrogen oxides
Can cause acid rain

15. Oil (Petroleum)
Liquid formed more than 300 million years ago from the remains of:
Diatoms (sea creatures the size of a pin head) which converted sunlight directly into stored energy.
