a method of burning coal underwater to reduce CO2 emissions

9. a filter that cleans power plants’ exhaust from coal combustion
a clean-coal technology that neutralizes acidic sulfur
compounds produced during combustion
a pressurized water vessel that is used to extinguish coal fires
Question 11
What technology can make coal a cleaner fuel?
Entry field with correct answer
fluidized-bed combustion

implementing a prewash of coal prior to combustion
using lower quality, high sulfur coal
mixing coal with natural gas to create a hybrid fuel

10. Question 12
A major public concern about nuclear power plants stems from
Entry field with correct answer
use of fossil fuels to run the reactors.
the higher consumer costs for electricity.
fear of nuclear accidents.
excessive emissions of greenhouse gases.
size of real estate needed to house the nuclear power plant
facility.
Question 13

11. The best example of an energy storage element in a solar energy system
is the
Entry field with correct answer

structural overhang that blocks sunlight in a passively cooled
home.
insulated windows in a passively heated solar home.
hot water tank of a solar hot water system.
sun-tracking mirrors in a power tower system.
Question 14
What is the fuel that is used to power a fuel cell?

12. Entry field with correct answer
direct solar input
propane
oxygen
uranium
hydrogen
Question 15
The major advantage of a fuel cell over a standard battery is that
Entry field with correct answer
fuel cells are less expensive to produce and operate than
standard batteries.
a fuel cell generates electricity without the need for positive or
negative electrodes but batteries have these electrodes.

13. fuel cells produce power as long as they are supplied with fuel
whereas batteries store a fixed amount of energy.
fuel cells generate small amounts of CO2 and sulfur oxide
emissions compared to the large amounts emitted by standard batteries.
fuel cells do not have any advantages over standard batteries.

14. Question 17
Electric meters can run backward for homeowners participating in net
metering. What does this mean?
Entry field with correct answer
homeowners receive meter credit for excess energy they
generate and supply to the utility’s power grid
the up front costs for installing renewable energy is recovered
by rewinding the home’s electric meter
if a homeowner uses less energy in one month than the
previous month, then the difference is subtracted from the electric meter
homeowners who voluntarily cut back on air conditioning use
are granted an electric credit
a radio controlled electric meter for remote monitoring allows
the utility company to stop the meter during peak demand periods
