Question 1

Today, the U.S. imports about what percentage of the oil it uses?
A) 10%
B) 25%
C) 40%
D) 60%
E) 80%

Accepted Answer

According to the Energy Information Administration (EIA), as of 2019, the U.S. imported approximately 60% of the petroleum it consumed.

Question 2

One of the primary motivating forces behind our per capita reduction in energy use in the
1980's was _____________.
A) a smaller population growth
B) higher oil prices
C) increased nuclear power costs
D) increased domestic oil discoveries

Accepted Answer

Higher oil prices in the 1980s incentivized people to reduce their energy use, leading to a per capita reduction in energy consumption.

Question 3

If you started with $100 in the bank and you had $200 after letting it sit there for 5 years, what would be the annual interest rate you received?
A) 2%
B) 5%
C) 10%
D) 14%
E) 22%

Accepted Answer

D

Question 4

Which of the following statements is true (only one):
A) The growth rate of energy consumption has kept pace with GNP growth.
B) Oil use has expanded more than any other fuel since 1940.
C) We reached the point last year where we imported no oil.
D) Electricity use has actually fallen since 1975.

Accepted Answer

According to the given statement, "Oil use has expanded more than any other fuel since 1940." This indicates that the growth rate of oil consumption has been higher than any other fuel, including electricity. Therefore, option B is the correct choice. Option A is incorrect because the statement does not mention the comparison between energy consumption growth and GNP growth. Option C is incorrect because it is a false statement. Option D is incorrect because the statement mentions that energy consumption has increased, but it does not provide any information about electricity use specifically.

Question 5

If the growth rate of the number of solar collectors is 7% per year, then 1000 units in use in 2010 will grow to _______ units by the year 2040.
A) 1200
B) 2000
C) 4000
D) 8000
E) 20,000

Accepted Answer

Using the formula for exponential growth, the number of solar collectors in 2040 can be calculated as:
N = 1000*(1.07)^30
N = 8000
Therefore, the number of solar collectors in use in 2040 would be 8000.

Question 6

Continued use of the fuels most relied upon in developing countries will eventually lead to ________.
A) depletion of soil nutrients
B) severe thermal pollution of water
C) increased oil prices
D) depletion of coal reserves in those countries

Accepted Answer

The continued use of traditional biomass fuels, such as wood and crop residues, in developing countries can lead to the depletion of soil nutrients as these materials are not returned to the soil to maintain its fertility.

Question 7

The Hubbert curve for an energy resource displays what quantity on the y-axis?
A) time
B) total production
C) yearly production
D) amount of fuel left

Accepted Answer

The Hubbert curve displays yearly production of an energy resource on the y-axis, showing the rate of production over time, typically peaking and then declining as the resource becomes less available.

Question 8

The most significant aspect of world consumption of energy over the last 40 years has
Been the ________.
A) growth of nuclear power
B) expanding use of oil
C) increased use of coal
D) emphasis on energy conservation
E) increase in our fossil fuel reserves

Accepted Answer

The expanding use of oil has been the most significant aspect of world consumption of energy over the last 40 years. Despite efforts to increase the use of renewable energy sources, oil remains the primary source of energy for transportation, industry, and residential use. The world's dependence on oil has also led to geopolitical tensions and environmental concerns.

Question 9

Which of the following is a non-renewable resource?
A) uranium
B) water
C) wind
D) biomass
E) radiant solar

Accepted Answer

Uranium is a non-renewable resource as it is a finite element found in the earth's crust and cannot be replenished in a short amount of time through natural processes.
