Self-Check Quiz Answers

Click each of the suggested answers below, and carefully compare your answers to the suggested answers.

If you have not done the quiz yet – STOP – and go back to step 1 above. Do not look at the answers without first trying the questions.

The best energy sources for an off-grid house are low-cost and easy to use.
  • Burning wood in a fireplace (or a wood furnace) is a good source of thermal energy for heating and cooking. Chopping down trees is an easy way to obtain wood -- assuming the house is near a woodlot of sufficient size to be renewable.
  • Solar energy is an effective off-grid energy option. Solar panels are expensive to buy, but they pay off over time. Solar energy can be used to heat water as well as generate electricity.
Compared to all other sources, tidal energy is not the best energy option. Tidal power can be generated only on coastlines with large tides, and not all coastlines have large tides. Although tidal energy can be added to the power grid already in place, the amount of electricity produces is unlikely to be sufficient for a large area or city.
At the moment, solar power is not completely reliable. On cloudy days, less solar power is produced and batteries are inadequate for large-scale storage of electricity. We still need energy sources other than solar to supply our energy needs.
The eco-club members could put such items as the following on their posters:
  • Turn off the lights when you leave a classroom.
  • Close outside doors quickly so heat does not escape.
  • Wear sweaters in the winter so the school boiler can be turned down.
  • Do not leave hot water taps running.
  • Bring a lunch that does not need re-heating in a microwave.
Your family might consider the following ways to use less electricity around the house:
  • Turn off the lights when you leave a room.
  • Hang clothes to dry instead of using an electric dryer.
  • Unplug electronics when they are not being used.
  • Use energy-efficient light bulbs.
  • Close the door! Keep warm air in during winter; keep hot air out during summer.
