A. more than a thousand years of U.S. demand, at presentconsumption rates

B. more than three centuries of U.S. demand (but less than athousand years), at present consumption rates

C. less than a century of U.S. demand, at present consumptionrates

D. None of the above

2.In the U.S., the vast majority of coal is sold almostexclusively to one energy consuming sector. Which sector?

A. industrial

B. residential & commercial

C. electric power

D. transportation

3.When the U.S. Energy Information Administration (the EIA)makes future projections of energy usage, they mostly focus onusing _______.

A. geologic formations and trapping structures

B. known amounts of oil in reserves

C. expected technological advances for finding more oil

D. predictions of future economics and gross domestic products(GDP)

4.In 2018, the greatest, and hence most important, source ofenergy for the entire world was _______.

A. petroleum and other liquids (i.e., oil)

B. natural gas

C. nuclear

D. coal

6.In 2017, the U.S. imported _____ of its daily crude oilsupplies and had domestic sources of ______ for its daily crude oilsupplies.

A. about 40%, about 60%

B. about 60%, about 40%

C. about 47%, about 53%

D. about 53%, about 47%

7.In about 2005, the American Petroleum Institute (API)suggested that within the U.S. alone, there was sufficient oil (117billion barrels) to supply 60 years of gasoline for 65 millioncars. Is this a reasonable solution for the United Statestransportation energy needs?

A. No, because there are actually more than 240 million cars andSUVs in the United States (i.e., in 2005 there were about 240million vehicles whereas today there are 260 million).

B. No, because the API is a lobbying agency which is known tospread false information.

C. Yes, because within 50 or 60 years, we will have createdviable renewable energy sources for transportation.

D. Yes, because the U.S. actually does have well over 100billion barrels of oil still unused in various rock formations,which is sufficient for our daily needs over the next 60 years.

9.Why did global oil reserves double, instead of decrease, from1980 to 2006?

A. Because coal was converted to oil.

B. Because significant amounts of new oil reserves werediscovered in geologic formations in a few previously unexploredcountries.

C. Because economic and political methods encouraged thereporting of more oil reserves in certain key countries.

D. None of the above.

10.Why is it difficult to know with certainty the amount ofextractable oil in rock formations?

A. There is frictional resistance to fluid flow in the rock porespaces.

B. The viscosity of the oil prevents total removal of all oil inthe pore spaces.

C. The amount of pore spaces and their connectivity (i.e.,permeability) vary throughout any rock formation.

D. All of the above
