Transcript of Fossil Fuels
What types of energy do we use?
What types of energy should we use?
pollution (air & water)
What are fossil fuels?
Well on land or sea
Oil gushes until peak production passed
Oil is held in the pore spaces in rocks
Oil is distilled into petrochemicals
Organization of Petroleum Exporting Countries
60% of oil in the market
Major Production Areas
Gulf of Mexico
(site of Deepwater Horizon Spill in 2010)
Alaska's North Slope
Formed with Oil
Mixture of gases, mostly methane (CH4)
Formation of Coal
Problems with Coal
Carbon dioxide (CO2)
Nitrogen oxides (NOx)
sulfur dioxide (SO2)
particulates (soot, fly ash)
other trace radioactive materials
Remove pollutants before emission
paying full environmental cost
taxing CO2 emissions (British Columbia)
cap & trade for carbon (EU, California)
synthetic natural gas?
