Which of the following best describes a potential advantage of using geothermal energy instead of solar farms for power generation?
Harnessing geothermal energy does not release hydrogen sulfide gas, whereas solar farms do.
Geothermal energy does not release greenhouse gases, whereas solar farms do.
Geothermal energy can be harnessed without destroying large tracts of habitat, whereas solar farms require large amounts of space
Geothermal energy is easily accessible and can be harnessed in most parts of the world, whereas solar energy is difficult to harness.
Solar energy systems have been increasing the percentage of energy they contributed to the global energy supply. One of the fastest growing types of solar energy systems uses photovoltaic (PV)(PV) cells. The graph below shows the solar power generated in one day in a town in Germany in the month of July.

Geothermal energy is used to run large and complex power stations as well as small and relatively simple pumping systems.
Which of the following most accurately explains how geothermal energy is produced and utilized in these applications?
Geothermal energy uses heat from the Sun to raise the Earth's surface temperatures to a point where these applications can heat homes and buildings.
Geothermal energy uses heat from the Sun to create atmospheric temperature gradients, which in turn power turbines to generate electricity.
Geothermal energy uses the natural insulating power of Earth to create temperature differentials that are used to heat buildings in the winter and cool them in the summer.

Which of the following is a disadvantage of using hydrogen fuel cells?
Hydrogen gas is not readily available on Earth.
The products of the reactions in hydrogen fuel cells damage the environment.
Hydrogen fuel cells are much less efficient in powering vehicles than internal combustion engines are.
Hydrogen fuel cells need to be very large to generate electricity.
Which of the following statements best describes a difference between nonrenewable and renewable energy sources?
