My colleague in Buenos Aires, Argentina, would like me to send him plans for a solar space heating system. Besides translating the plans into Spanish, what other difference might I suggest for implementation of the plans?
The solar collector box should be placed on the north-facing side of the house instead of the south-facing side.
The solar collector box should be placed on the west-facing side of his house to collect the morning sun.
The color of the box should be light blue to complement the colors of the Argentine flag.
Because it will be used in the Southern Hemisphere, the warm air will settle; therefore, the warm air duct must be on the bottom of the collector.
Because Buenos Aires is close to the equator, he might decide to install curtains inside the collector box.

11. 14.6
Criticisms pitched against the use of solar energy include
the sun doesn’t shine very brightly on cloudy days and not at all at night.
much of the U.S. receives too little strong solar radiation, especially seasonally.
there’s nothing to be consumed, so limited profit can be made.
the technology is still relatively expensive.
all of the above.

Which of the following is a valid criticism of damming rivers for hydroelectric power generation?
The body of water behind a dam often displaces people and alters habitat for many organisms.
Increased availability of water often results in irrigation for agriculture, leading to increasing levels of siltation behind the dam.
Damming rivers generally changes relatively cool moving water into warmer, less-oxygenated water that can’t support many resident fish species.
Reduced water downstream interferes with fish migrations and lifestyles of Native Americans tied to the fish.
Dam construction has been criticized for all of the above.

Subsidies for renewable or alternate energy sources
are criticized by opponents who label them as unfair and a burden upon consumers.
make the sources more competitive with energy production from fossil fuel.
could be compared to subsidies provided to fossil fuel producers, including government costs for cleaning up pollution or maintaining access to foreign oil.
allow for investment and research that should ultimately pay off when fossil fuel supplies dwindle.

Which of the following is NOT true about utilizing biomass energy?
Burning biomass is a relatively renewable energy source compared to fossil fuels.
This renewable energy source can be tapped without pollution or negative impact upon global climate.
Municipal wastepaper and other organic wastes can be burned to produce electricity.
Burning of municipal wastes also reduces the materials destined for landfills.
Technologies have been developed that are highly appropriate for the production of methane for combustion in developing countries.
