Chapter Overview
This chapter explains renewable energy sources. Solar, hydroelectric, wind,
ocean, biomass, geothermal, and fuel cells are described in detail. How these
energy sources function and their availability is essential information for the AP
exam. Costs and benefits of each are also important to know.

Discuss the implications of the statement “For an average home, standby
appliances can represent up to 25 percent of the monthly electric bill” and the
representation in Figure 20.4. You may want to include calculations as a part of
this discussion. Using an electric bill the students can calculate how much energy
and money is used for each of these standby appliances. It is a good idea to get
students comfortable with the units used on electric bills, for instance kilowatt
hours. Students often do not understand the meaning of these units.

Questions for Discussion:
1. How does energy efficiency come into play when so much energy is wasted
when utilizing “instant on” features in household electronics?
2. The typical incandescent lightbulb is only 5 percent efficient. What can you
do to improve the efficiency of your household lighting?
The automotive industry is gradually phasing in hybrid engine and alternative
fuel technology.
3. What barriers do you see in implementing these hybrids and alternative fuels
on a large scale?
4. What workable solution can you propose to facilitate the change?
