Summary
Congratulations! You are now an expert on the generation and use of
clean energy. You have learned how to determine how much electricity
you are using. Were you surprised by the number of devices you have
that require electricity? You also know that:
-
Hydroelectric, wind, and sunlight can each be
used to generate electricity without causing pollution.
-
Batteries can store the extra electricity that
is produced (for example, when it is very windy or sunny), so
that the energy is available at times of low production.
-
We can, if we wish, provide electricity for our
homes even without being connected to power lines.
There are two more exercises to complete before you
have finished the unit: a quiz and an evaluation form.
-
Click on the quiz link (below) to test yourself
and see how much you have learned. (Hint: if
you do get a question wrong, you can answer it again for partial
credit.)
-
After you complete the quiz, fill out the
feedback form for this unit. Once this is submitted, you're
finished!
