Nonrenewable vs. Renewable?• What is the difference
between nonrenewable and renewable?
• What is net energy?
OIL• 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?• 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
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 CO2 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 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
Natural Gas• What is natural gas?
– Mostly Methane– Large gas bubbles found above
reservoirs of crude oil• “Clean-burning” fuel – no
toxic chemicals– Still produces carbon dioxide
Hydraulic Fracturing• Hydraulic 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
