question 25 of 30
what is one advantage of geothermal and solar power?

a. they are inexpensive.

b. they can be used anywhere.

c. they are easy to transport.

d. they do not produce greenhouse gases.

Explanation:

• Option A: Geothermal and solar power systems often have high initial costs, so they aren't inexpensive.
• Option B: Solar power depends on sunlight availability (e.g., less effective in areas with constant cloud cover or at night), and geothermal power requires specific geological conditions (e.g., areas with geothermal reservoirs), so they can't be used anywhere.
• Option C: Geothermal energy is typically used on - site where the geothermal reservoir is, and solar energy, while its electricity can be transported, the energy capture (sunlight) isn't transported easily, so they aren't easy to transport.
• Option D: Geothermal power (when using steam from geothermal reservoirs for electricity generation) and solar power (photovoltaic or solar thermal) produce little to no greenhouse gases during operation, unlike fossil - fuel - based energy sources.

Answer:

D. They do not produce greenhouse gases.
