Which placement of a wind farm would produce the most energy?
In the city
On farmland
In the desert
Offshore wind farms found in the ocean
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.
In the majority of less developed countries, the major source of energy for domestic use is which of the following?
oil
coal
biomass
Nuclear
geothermal
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
Which of the following best describes an advantage of burning biomass rather than burning fossil fuels in developing countries?
Biomass production requires less open space than fossil fuel extraction does, so land is available for other purposes.
Burning biomass is associated with fewer human respiratory concerns than fossil fuels are because it does not give off sulfur oxides and nitrogen oxides.
Biomass production is cheaper than fossil fuel extraction, making it more readily available for use.
Burning biomass is more efficient than burning fossil fuels, providing more available energy from less of the resource.
An industry uses natural gas for manufacturing and uses the waste heat to produce electricity. This is an example of which of the following processes?
Cogeneration
Electrolysis
Gas hydration
Gasification
Reclamation
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
Increasing the cost to use public transportation
Offering tax incentives to individuals who recycle clothing and home goods
Subsidizing the cost of solar panel installation for homeowners
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.
Based on the diagram, which processes would provide the energy used to generate electricity at the power plant?
Absorption of incoming solar radiation
Fusion of atomic nuclei to form heavier nuclei
Combustion of fossil fuels
Fission in radioactive fuel
Which of the following describes an environment where large amounts of oil could form millions of years in the future?
A volcanic island located along the mid-ocean ridge
A large glacier in a mountainous area
A river delta in a forested region
An area of sand dunes in a desert
True or false: global oil reserves are increasing in our lifetime
true
false
Examples of fossil fuels are:
wind, solar, wave, hydro
coal, oil, gas
nuclear
geothermal
Nuclear power is more advantageous over fossil fuels for energy consumption because:
it is extremely dangerous if something goes wrong
It does not emit carbon dioxide and so does not contribute to global warming.
there will always be a small probability of failure and the associated risk are high
it is renewable
According to the pie chart, Australia's energy mix is predominantly made up of renewable energy?

47%
21%
15%
85%
