Which of the following best describes a benefit of increasing the number of offshore wind farms rather than onshore wind farms?
Offshore wind farms will consume less water during operation than wind farms on land because the turbines require less steam for electricity generation.
Offshore wind farms will decrease the maintenance costs associated with electricity generation because they are cheaper to operate than wind farms on land.
Offshore wind farms will emit less carbon dioxide and carbon monoxide than wind farms on land because they are farther from urban areas.
Offshore winds farms will produce up to three times as much electricity as wind farms on land because of increased wind speeds offshore.
Which of the following best describes the energy resource used most often for heating and cooking in less developed countries?
Bituminous coal is primarily used because of its relative abundance and high moisture content.
Cogeneration from fuel oil systems is primarily used because it has low up-front costs.
Biomass is the predominant fuel source because it is easily obtained locally.
Natural gas is the most prevalent fuel source because it is readily available and produces few air pollutants.
How many BTUs were consumed in the United States in 2017 by consumers that used petroleum as a fuel source?
28 quadrillion BTUs
36 quadrillion BTUs
62 quadrillion BTUs
97 quadrillion BTUs
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?
2,000
8,000
20,000
80,000
100,000
Which of the following is a drawback to using biofuels, such as ethanol, as a fuel source?
Ethanol-blended gasoline has higher carbon emissions than petroleum alone.
The global demand for biofuels is continually decreasing.
There is high energy investment in producing and processing the crops needed for ethanol production.
Ethanol-blended gasoline increases the likelihood of freezing gas lines in winter months.
