Uses of fossil fuels

• Energy for transportation, farming, and industry
• Crude oil unrefined petroleum
• Petrochemical petroleum products such as
  plastics, fabrics, medicienes, tar, wax, ruber,
  insecticides, fertilizers, detergents, shampoo

Fossil fuel supplies

• Nonrenewable
• Coal is most abundant
• US, Russia, China have 2/3 of reserves
• 200 years of reserves
• 75 of petroleum has been discovered
• Rest probably under ocean
• 90 in ground
• A lot of natural gas still not discovered
• Down very deep, miles
• Oil shale contains petroleum - to extract

10
Fossil fuels and the environment

• Strip mining damage
• Topsoil displaced
• Erosion issues
• Gives off acids
• Air pollution when burned
• Acid rain
• Spills of oil wells, tankers,
• and pipelines harm wildlife and oceans
