3. Which sector of society uses the most energy?

  • residential

  • industry

  • transport

  • commerce

4. Energy efficiency is defined as:

  • the amount of energy in a fossil fuel

  • the amount of energy you get from a system divided by the total energy you put into the system.

  • the amount of energy gained minus the amount of energy lost

  • the amount of energy lost to the environment

5. Electrical energy can be obtained from which of the following?

  • mechanical energy

  • thermal energy

  • chemical energy

  • all of the above

6. Solar, geothermal, wind, biomass, and hydropower are considered renewable because they:

  • convert directly into heat and electricity

  • are replenished by nature within a relatively short span of time

  • are free to use

  • do not produce pollution

7. Compared to fluorescent bulbs, incandescent light bulbs:

  • use less energy

  • use the same amount of energy

  • use more energy

  • are always brighter and last longer

8. Global warming primarily is concerned with the increase of which gas in the atmosphere?

  • carbon dioxide

  • oxygen

  • nitrogen oxides

  • sulfur oxides

9. Uranium atoms in a nuclear power plant:

  • combine with each other to release energy

  • split to release energy

  • are burned to release energy

  • release electrons as usable electricity

10. Energy in fossil fuels is stored as:

  • nuclear energy

  • electrical energy

  • chemical energy

  • thermal energy

11. Energy from the sun is harnessed for:

  • photovoltaic cells

  • wind power

  • passive solar heating

  • all of the above

12. Electricity is the movement of:

  • atoms

  • neutrons

  • molecules

  • charged particles, such as electrons or ions

13. Natural gas and propane are burned to release energy. Why is propane more often used in rural areas and for gas grills?

  • It’s cheaper.

  • It’s safer.

  • It’s easier to store and transport.

  • It burns more cleanly.

14. The highest quality coal for energy purposes is:

  • lignite

  • anthracite

  • bituminous

  • sub-bituminous

15. Until recently, only which country could produce the steel reactor vessel needed for nuclear power plants?

  • United States

  • United Kingdom

  • Japan

  • Brazil

16. Which fossil fuel is refined to make gasoline?

  • natural gas

  • oil

  • coal

17. Solar ponds are unable to heat water as hot as water heaters.

  • true

  • false

18. Your home may lose a lot of heated air in the winter and cooled air in the summer if you:

  • have ductwork located in the attic or crawlspace.

  • use double-paned windows.

  • use black-out curtains and window coverings.

  • place your heating/cooling unit in a basement.

19. Approximately how much energy from a coal-burning power plant actually gets converted into electricity?

  • one quarter

  • one third

  • one half

  • three quarters

20. Energy conversions most often produce:

  • motion

  • light

  • heat

  • sound
