Nuclear energy is generated by the process of nuclear fission.
Nuclear power plants convert water to steam, similar to fossil fuel–burning power plants.
Which of the following is a characteristic of nonrenewable energy sources that distinguishes them from renewable energy sources?
The construction of power plants that use nonrenewable energy sources is typically more expensive than the construction of those that use renewable energy sources.
Nonrenewable energy sources are typically less harmful to wildlife and ecosystems than renewable energy sources are.

Nonrenewable energy sources typically take a longer time to replenish than renewable energy sources do.
Which of the following explains why some energy sources are renewable?
Renewable energy sources exist in a fixed amount and cannot be easily replaced.
Renewable energy sources can be replenished naturally, at or near the rate of consumption.
Renewable energy sources include natural gas and other fossil fuels because they are made from the remains of ancient organisms.
Renewable energy sources use advanced technologies and have been discovered in recent years, making them newer energy sources.

Purity is a major factor in determining the type of coal used for energy. Which of the following types of coal are correctly paired with a description of its purity and common use?
Anthracite is considered the highest grade coal because it is almost pure carbon, and it is often used for domestic heating.
Metallurgical coal is most widely available and contains 60-86% carbon, which makes it ideal for use in coal power plants.
Steam (bituminous) coal has a high carbon content with low amounts of impurities, which makes it ideal for use in the steel industry.
Lignite is the most mature and purest form of coal, and it is often used for large-scale power generation.
Which nation has the largest coal reserves?
United States
Russia
China
Australia
Which nations contain 80% of the world's oil reserves?
NATO
UN
OPEC
SFWMD
Which of the following best describes an environmental problem associated with hydrologic fracturing, or fracking?
Fracking has led to an increase in the production of oil and natural gas, lowering energy prices.
Fractures in the shale will close up once the fracking fluid is removed unless fine particles, like sand, are introduced to hold them open.
The products of fracking release more carbon dioxide and sulfur compounds into the atmosphere than other fossil fuels.
Fracking fluids can escape from the drill hole and contaminate surface water and groundwater.
Which of the following would be most likely to be used as a fuel source for electricity generation in a nuclear power plant?
Uranium-235
Cesium-137
Iodine-123
Yttrium-90 and Yttrium-91
Which structure was the site in the nuclear power plant accidents at Three Mile Island and Chernobyl occurred?
Containment unit/Reactors
Reservoir
Condenser
Generator
Which of the following statements correctly explains the role of fossil fuels in the production of energy?
The combustion of fossil fuels heats water to produce steam, which then turns a turbine.
The steam released from the combustion of fossil fuels turns a generator, which then powers a turbine.
The steam released from the combustion of fossil fuels turns a generator, which then powers a turbine.
Steam produced from a turbine ignites the fossil fuels, which then powers the generator.
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 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.
Throughout the world, especially the less-developed countries, burning wood or other biomass for heating or cooking in homes is common. One negative environmental impact of this practice is the production of particulates indoors, which can be a health hazard to humans.
Which of the following describes the best strategy for mitigating this potential problem?
Installing effective ventilation systems in dwellings
Updating dwellings with well-sealed windows
Planting native plants around the dwelling
Equipping dwellings with rainwater collection systems
Which of the following best describes a disadvantage of geothermal energy production?
Geothermal energy production is a significant source of noise pollution.
Geothermal energy implementation in homes and businesses has a high upfront cost, and electricity is needed to operate pumps.
Geothermal energy generation costs remain stable when gas and oil prices increase.
Geothermal energy is weather dependent and can be generated only at certain times of the year.
Which of the following best explains the process of electricity generation in a hydrogen fuel cell?
At the cathode, water reacts with oxygen to release hydrogen and heat. Electricity is generated as the bonds form between hydrogen and oxygen. The by-product of the reaction is heat.
At the cathode, hydrogen is reduced and then electrons flow to the anode to generate electricity. Oxygen is produced at the cathode. Oxygen and heat are the by-products of the reaction.
At the anode, hydrogen is oxidized and electrons flow in a circuit to the cathode. At the cathode, oxygen reacts with the hydrogen to produce water. Water and heat are by-products of the reaction.
At the anode, hydrogen is oxidized and electrons pass through an electrolyte to the cathode. There, the protons react with water to produce oxygen. Water and heat are by-products of the reaction.
