OIL Crude oil (petroleum) Crude oil (petroleum) is a thick liquid containing hydrocarbons that we extract from underground deposits and separate into products such as gasoline, heating oil and asphalt.
Where is all the oil? What is OPEC?What is OPEC? Organization of Petroleum Exporting Countries –11 of these countries have 78% of the world’s proven oil reserves and most of the world’s unproven reserves. What happens when oil supply goes down? How about when it goes up? –Supply and Demand
US Oil Prices 1951-2006 Why is there a huge spike in 1973 and 1979?
U.S. Oil? The U.S. – the world’s largest oil user – has only 2.9% of the world’s proven oil reserves.
Burning of Oil Burning oil for transportation accounts for 43% of global CO 2 emissions. Can release chemicals known to harm human health, like CO, VOCs, Pb etc.
How Would You Vote? Do the advantages of relying on conventional oil as the world’s major energy resource outweigh its disadvantages?
Oil Shale Oil Shale kerogenOil Shale is a solid combustible mixture of hydrocarbons called kerogen. –Heavy Oil –High Sulfur Content –Extracting produces: Toxic waste Uses and contaminates large volumes of water Net energy is not as high
Hydraulic Fracturing Hydraulic Fracturing FrackingHydraulic Fracturing AKA Fracking Drill and inject fluid into the ground at high pressure in order to fracture, or break, shale rocks to release natural gas –“fluid” consists of water and chemicals that can contaminate groundwater
