Energy Resources

Which is an example of a nonrenewable energy resource?

• petroleum
• solar energy
• wind energy
• geothermal energy

Which problem is most likely to result from the use of nuclear power?

• pollutants in the groundwater after drilling
• storage of radioactive wastes
• miners getting trapped underground
• oil spills that pollute oceans and beaches

Which is the most likely result of not conserving energy?

• improved fuel efficiency
• improved air quality
• decreased energy costs
• decreased supply of energy

Which is a possible disadvantage of using biomass as fuel?

• Using crops for biomass fuels rather than food may affect the price and supply of food.
• Biomass is a nonrenewable energy resource that is gone for good once it is used up.
• Using biomass fuels in cars causes them to burn more gasoline.
• Using biomass is possible only in a few places in the world with the correct conditions.

Which renewable resource comes from the energy of moving water?

• solar power
• hydropower
• wind energy
• biomass

Which best describes renewable energy resources?

• Renewable energy resources can be replaced as they are used or cannot be used up.
• Renewable energy resources include fossil fuels such as oil and natural gas.
• Renewable energy resources have not impact on the environment.
• Renewable energy resources currently provide most of the energy in the United States.

Critics say that electric cars are not as pollution-free as people think. Why?

• Electric cars burn fuels that release carbon dioxide into the air.
• Electrical energy is often produced by power plants that burn fossil fuels.
• The process of distributing electrical energy releases carbon dioxide.
• The energy used by electrical cars comes from renewable energy resources.

Which is a disadvantage of solar energy?

• Solar energy cannot be used to turn turbines.
• The sun is too far away to provide enough energy.
• Solar panels produce pollutants that lead to global warming.
• Photovoltaic cells do not produce electricity at night.

Which is most likely to conserve energy resources?

• using public transportation
• using nuclear energy instead of solar energy
• turning thermostats higher in winter
• burning coal instead of using hydropower

Which is an advantage of using nuclear power plants?

• They use renewable energy resources.
• They do not cause air pollution.
• They change radioactive substances into harmless substances.
• They produce unlimited electrical energy.
