This activity contains 15 questions.

	Hydrogen gas is often called the fuel of the future. The problem with hydrogen gas as a fuel is that it   requires very high ignition temperatures to start the fusion reaction. would be very polluting to burn. all must be produced using a primary energy source. would upset the hydrological cycle. is a nonrenewable resource that would quickly be exhausted.

	Which of the following is not an indirect form of solar energy?   hydropower geothermal ocean thermal energy conversion wind biomass

	OTEC is a(n)   means of extracting energy from the thermal gradient of ocean waters. technology for production of methane from biomass. experimental technology for energy production via thermal oxidation of carbon. organization of oil-rich countries that manipulates the availability and price of petroleum. method of producing hydrogen gas using solar energy.

	Which of the following is not true about tidal power?   Energy could be generated during both the incoming and the outgoing tides. Significant adverse environmental impacts would accompany tidal power plants. Water flowing in or out with the tides would spin a turbogenerator. There are currently no working tidal power plants in operation. Tidal levels are insufficient for use as an energy source in most areas of the world.

	Flate-plate collectors   catch manure under livestock stalls for later production of methane gas. are large arrays of photovoltaic cells. are used to heat water by solar energy. catch the force of the wind to spin a turbogenerator. capture hydrogen gas released by the electrolysis of water.

	The power grid is   also called the power tower, and has been taken out of service due to the costs of upkeep. the optimal spatial arrangement of wind turbines at a wind farm. the reaction chamber inside a hydrogen-oxygen fuel cell. the network of fluid-filled tubes in a roof-mounted solar water heater. the network of electrical lines that carry electricity from power plants to customers.

	Which is the oldest form of direct or indirect solar energy?   flat-plate collectors solar-trough collectors hydropower photovoltaics ocean thermal energy conversion

	Which of the following is not true of wind power?   It has been used for hundreds of years. It releases no greenhouse gases or acid-forming emissions. It provides a constant, uninterruptible source of energy. It can be used to produce electricity. It was popular in rural America early in this century.

	Three main problems arise when the Sun is not shining. These may be categorized as   collection, conversion, and storage. collection, conversion, and distribution. indoor, outdoor, and rooftop. water heating, air heating, and generation of electricity.

	There are currently two economically viable ways of producing electricity from sunlight. These are   photovoltaic cells and solar-trough collectors. power towers and dish/engine systems. rooftop collectors and passive solar collection.

	Geothermal energy is   the use of naturally heated water or steam to heat buildings or drive turbogenerators. a heating system that uses hot-water pipes embedded in flooring within a home. heat derived from the crushing of large quantities of rock. heat derived from molten lava.

	Which of the following statements is not true of energy policies?   The traditional fuel industry enjoys an economic advantage because its damage to the environment and human health is often discounted or overlooked. Despite the environmental disadvantages of traditional fuel use, importing crude oil is extremely beneficial to the country's economy. The traditional fuel industry is heavily subsidized by tax write-offs. The traditional fuel industry is heavily subsidized by military support to assure access to oil in the Middle East. The traditional fuel industry is heavily subsidized by leasing of public lands at low prices, encouraging exploitation of fossil fuel resources.

	A carbon tax is   a tax on fuels containing carbon. a tax on compounds containing carbon. a tax on carbon dioxide a tax levied on all fuels according to the amount of carbon dioxide produced in their consumption.

	Over the last 25 years, the market for photovoltaic cells has____________   remained stable. increased dramatically. declined. increased slightly.

	Which of the following statements about hydropower dams is untrue?   Hydropower dams and large reservoirs displace large numbers of people. Hydropower is an unreliable and nonrenewable source of energy. Hydropower dams impede or prevent the migration of fish. Dam building can cause downstream changes like increased water temperature and fluctuating water levels.
