Which of the following is the best example of cogeneration?

A coal-fired power plant captures waste heat and uses it to heat adjacent buildings.

Some solar energy systems produce high-temperature water for industrial applications and produce steam to run turbines that generate electricity. What type of solar energy system is needed for these kinds of applications?

A solar collector system using mirrors or lenses to concentrate sunlight

An industry uses natural gas for manufacturing and uses the waste heat to produce electricity. This is an example of which of the following processes?

Cogeneration

In an apartment building, exhaust from a gas-powered electrical generator is captured to produce hot water to heat a swimming pool. Which of the following is illustrated by this process?

Cogeneration

Which of the following accurately describes a fuel cell vehicle?

Fuel cell vehicles use hydrogen to generate electricity that runs the motor.

(A) Photovoltaics (B) Geothermal (C) Biomass (D) Hydroelectric (E) Hydrogen fuel Drawbacks include noise and the release of corrosive chemicals

Geothermal

Throughout the world, especially the less-developed countries, burning wood or other biomass for heating or cooking in homes is common. One negative environmental impact of this practice is the production of particulates indoors, which can be a health hazard to humans.

Installing effective ventilation systems in dwellings

Which of the following is a true statement about passive solar heating?

It is based in part on the principle of the greenhouse effect.

Many environmentalists consider Egypt's Aswan High Dam on the Nile River to be an ecological disaster. Which of the following is the best evidence to support this viewpoint?

Most of the nutrient-rich silt that the Nile annually deposited downstream is now deposited behind the dam.

A) Photovoltaics (B) Geothermal (C) Biomass (D) Hydroelectric (E) Hydrogen fuel Converts solar energy directly into electrical energy

Photovoltaics

Which of the following actions would reduce global greenhouse emissions?

Replacing coal-burning power plants with wind farms

Which of the following best describes how the use of hydrogen fuel negatively impacts the environment?

The energy needed to produce the hydrogen fuel may come from fossil fuels, whose use contributes to ocean acidification and global climate change.

Which of the following statements about geothermal energy is accurate?

The location of geothermal energy sources ranges from short distances below ground to miles below the surface.

Which of the following best describes the method of vehicle transport that is the most environmentally sustainable?

The use of a vehicle powered by hydrogen fuel cells because there are no carbon emissions

The primary cause for the decline in the use of wood as a fuel in the eighteen hundreds was the

reduced wood availability resulting from widespread deforestation

In many parts of the United States, homeowners use a significant portion of their energy budget to heat their home in the winter. It has been determined that lowering a thermostat by 3°F3°F in the winter can reduce the energy costs by about 1010 percent in many homes. An individual homeowner lowers their thermostat by 33 degrees exactly halfway through the billing period. For the month that the thermostat was lowered, the heating bill was $95$95. How much money did the family save in the month in which they lowered the thermostat setting halfway through the billing period?

$5.00

If an incandescent lightbulb used for lighting has an efficiency rating of 5 percent, then for every 1.00 joule of electrical energy consumed by the bulb, which of the following is produced?

0.05 joules of light energy

A home uses ten 100-watt lightbulbs for five hours per day. Approximately how many kilowatt-hours of electrical energy are consumed in one year by using the lightbulbs?

1,825

Which of the following would be the best location for a wind farm with ten industrial turbines?

Arranged uniformly on a local farm that has fields and pastureland for dairy and grain production

Which of the following best explains the process of electricity generation in a hydrogen fuel cell?

At the anode, hydrogen is oxidized and electrons flow in a circuit to the cathode. At the cathode, oxygen reacts with the hydrogen to produce water. Water and heat are by-products of the reaction.

In the majority of less developed countries, the major source of energy for domestic use is which of the following?

Biomass

Which of the following best describes an advantage of burning biomass rather than burning fossil fuels in developing countries?

Biomass production is cheaper than fossil fuel extraction, making it more readily available for use.

Which of the following energy sources is not derived directly or indirectly from solar energy?

Geothermal

Which of the following best describes a disadvantage of geothermal energy production?

Geothermal energy implementation in homes and businesses has a high upfront cost, and electricity is needed to operate pumps.

Which of the following PVPV panel systems is least effective at producing energy?

No tracking, tilted east

The graphs below show the energy output of one kilowatt of photovoltaic (PV)(PV) capacity of different PVPV panel systems over a day (graph on the left) and the annual energy production (graph on the right) of the same systems. Dual-axis tracking means that the PVPV panels are constantly moving to always face the Sun directly. If the PVPV panels are tilted in a fixed position, the direction of tilt is indicated. Flat PVPV panels are not tilted in any direction. Which one peaks at 2 p.m.?

No tracking, tilted west

Which of the following best describes a benefit of increasing the number of offshore wind farms rather than onshore wind farms?

Offshore winds farms will produce up to three times as much electricity as wind farms on land because of increased wind speeds offshore.

Which of the following is a way for the government to encourage efficient energy use?

Requiring higher fuel economy standards for new cars

Which of the following is a drawback to using biofuels, such as ethanol, as a fuel source?

There is high energy investment in producing and processing the crops needed for ethanol production.

Which of the following is the most practical solution to maximizing energy production at wind farms while minimizing the risk to wildlife?

Turn off turbines during periods of maximum migration.
