B: Biogas is produced when anaerobic bacteria digest organic matter in the absence of oxygen.
C: Biomass energy has many advantages and few, if any, deleterious side effects.
D: Corn grown specifically fro biogas production can be expected to increase in the U.S.

3:  The primary drawback to using the sun directly as a power source is that its energy is
A: intermittent.
B: weak.
C: unavailable.
D: dispersed.

4:  Passive solar techniques
A: are not applicable to large modern buildings and apartment complexes.
B: require the use of thermal masses to be effective.
C: are of little use if all the windows face the north.
D: are used more today than our ancestors did.

5:  Which of the following statements is most probably true?
A: Solar water heaters in the U.S. are rare because initial costs are too high.
B: Power towers produce electricity at rates that few could afford.
C: The main constraint in the use of photovoltaics is underdeveloped technology.
D: Money spent on R and D of solar power has recently surpassed the R and D expenditures of nuclear power.

6:  Which of the following statements about wind power is true?
A: Wind power technology is in its infancy, too early to allow it significant energy contributions.
B: The most concrete environmental problem of wind power is bird death.
C: Wind power expansion has slowed in recent years, especially in Europe.
D: Wind power could supply almost 100 percent of America's energy needs if fully developed.

7:  Which of the following statements is true about geothermal energy?
A: Geothermal power is most practical along plate margins.
B: The first commercial hot dry rock power station is in operation in Great Britain.
C: Geothermal power is unique in that pollution is not a byproduct.
D: Geothermal energy exploitation, like hydropower, has leveled off worldwide.

8:  Which of the following is true about ocean energy?
A: Tidal power is commercially feasible anyplace there are ocean tides.
B: Commercial OTEC plants are widely established in the Caribbean.
C: In most locations, the difference between high and low tide is not great enough to efficiently drive a turbine.
D: Ocean energy technology and funding has vastly increased in recent years because of renewed interests in this technology.

9:  Which of the following is true about energy storage methods?
A: The biggest drawbacks for batteries are its weight and bulkiness.
B: Electric cars comprise ten percent of California's vehicles at the present time.
C: Little hope exists for developing improved batteries since we are at the limits of the technology.
D: Flywheels, although easy to operate, exhibit low efficiencies.

10:  Which of the following is true about energy efficiency?
A: In general, the LDCs are less energy-efficient even though they may use less energy overall and per capita.
B: Cogeneration plants have been more successful serving large rather than small communities.
C: Voluntary energy conservation can be best achieved (according to the authors) through tax incentives.
D: Americans seldom sacrifice and usually have to be forced to give up their luxuries.
