On an annual basis, the per capita electricity usage in Ethiopia is approximately what percent of the per capita electricity usage in the United States?

0.2

What was the approximate percent increase in consumption from 1986 to 1997 ?

20%

Burning one gallon of gasoline in a car releases approximately 20 pounds of CO2 into the atmosphere. One person drives 60,000 miles in a car that averages 30 miles per gallon (mpg), while another person drives 60,000 miles in a car that averages 20 mpg. Over the course of the 60,000 miles, how many fewer pounds of CO2 are released by the 30 mpg car than by the 20 mpg car?

20,000

A family of five recently replaced its 5-gallon-per-minute showerheads with water-saving 2-gallon-per-minute showerheads. Each member of the family averages 8 minutes in the shower per day. In a 30-day period, how many fewer gallons of water will the family use with the new showerheads?

3,600

The number of years that the power plant will be capable of supplying all of the demand for energy in the three cities is nearest to

5 years

At the 1997 rate of consumption, about how long will the estimated 2,000 billion barrels of oil last?

75 years

Which of the following is the best example of cogeneration?

A coal-fired power plant captures waste heat and uses it to heat adjacent buildings.

Which three sources supply the majority of commercial energy in the world today?

Coal, oil, and natural gas

The cities of Edmonton and Calgary are relatively far north and at high elevation. Which of the following best explains the data presented in their ecological footprints?

Colder average temperatures and longer nights in Edmonton and Calgary lead to high energy usage to heat and light homes.

Which of the following best illustrates the concept of the tragedy of the commons?

Depletion of an aquifer by regional farmers

Which of the following is the most valid inference regarding electricity production, based on the graph above?

Electricity production from coal began to decrease in 2008 because of the increasing use of natural gas and renewable energy

Based on the data, which of the following policies would most likely make the greatest reduction in the ecological footprint for all of the cities shown in the graph?

Setting higher fuel efficiency standards for vehicles

According to the data plotted in the graph above, which of the following is true about the increase in world fossil fuel consumption between 1965 and 1980 ?

The increase in oil consumption outpaced the increases in coal and natural gas consumption.

Between 1960 and 1970, world oil consumption approximately doubled. Which of the following explanations is consistent with this increase?

The number of cars on the road increased.

An advantage of using natural gas rather than oil, as a fuel is that natural gas is

cleaner because it burns more completely

There are various stages in the formation of coal as heat and pressure are increased and moisture content is decreased. These stages, in order, are

peat, lignite, bituminous, anthracite

Is renewable
