Energy

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 renewable resource comes from the energy of moving water?

• solar power

• wind energy

• hydropower

• 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 no impact on the environment

• renewable energy resources currently provide most of the energy in the United State

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 come 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 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

which is a possible consequence of using hydropower to produce electricity?

• dams may flood areas upstream

• radioactive wastes may be produces

• air pollution may increase

• more fossil fuels may be used

Why is it important to conserve energy even from renewable resources?

• renewable energy resources cannot be replaced after they are used

• using renewable energy resources causes more pollution than using nonrenewable resources

• renewable energy resources produce radioactive wastes

• every kind of renewable resources has some disadvantages
