Energy Resources Review

Which of the following is a characteristic of nonrenewable energy sources that distinguishes them from renewable energy sources?

• Nonrenewable energy sources require new technology in order to be used than renewable energy sources do.

• Nonrenewable energy sources are typically less harmful to wildlife and ecosystems than renewable energy sources.

• Nonrenewable energy sources typically take a longer time to replenish than renewable energy sources do.

• The construction of power plants that use nonrenewable energy sources is typically more expensive than the construction of those that use renewable energy sources.

How many BTUs were consumed in the United States in 2017 by consumers that used Coal as a fuel source?

• 14 quadrillion BTUs

• 25 quadrillion BTUs

• 28 quadrillion BTUs

• 36 quadrillion BTUs

Which three sources supply the majority of commercial energy in the world today?

• Nuclear, hydropower, and photovoltaics

• Wood, dung, and charcoal

• Coal, oil, and natural gas

• Solar, wind, and biomass

Which of the following is used more often in developing countries?

Choose the correct order from highest moisture content to highest carbon content.

• Peat -> Lignite -> Bituminous Coal -> Antracite

• Antracite -> Bituminous Coal -> Lignite -> Peat

• Peat -> Lignite -> Antracite-> Bituminous Coal

• Lignite -> Peat -> Antracite-> Bituminous Coal

What is the dirtiest fossil fuel?

• Diesel

• Oil

• Natural gas

• Coal

What is the cleanest of the three fossil fuels?

• Nuclear

• Petroleum

• Oil

• Natural gas

How is energy from fossil fuels produced?

• The combustion of fossil fuels heats water to produce steam, which then turns a turbine.

• The heat released from burning fossil fuels rises and turns a turbine, which then releases carbon dioxide

• The steam released from the combustion of fossil fuels turns a generator, which then powers a turbine.

• Steam produced from a turbine ignites the fossil fuels, which then powers the generator.

What is the common fuel for nuclear powerplants?

• Hydrocarbons

• Uranium

• Zinc

• Cadmium

Which best represents how solar energy is produced in photovoltaic cells?

• The sun's rays boil water producing steam and turning a turbine

• The Sun’s rays warm air that turns propeller blades attached to a rotor.

• Photons of light excite electrons that result in an electric current

• Photons of light activate a generator that converts chemical energy into mechanical energy.
