Question

which of the following is a characteristic of nonrenewable energy sources that distinguishes them from renewable energy sources?
a the construction of power plants that use nonrenewable energy sources is typically more expensive than the construction of those that use renewable energy sources.
b nonrenewable energy sources are typically less harmful to wildlife and ecosystems than renewable energy sources are.
c nonrenewable energy sources typically require additional new technology in order to be used than renewable energy sources do.
d nonrenewable energy sources typically take a longer time to replenish than renewable energy sources do.

Explanation:

• Option A: Construction costs vary. Some renewable (like large - scale solar farms) can be costly. Non - renewable (e.g., simple coal - fired plants) may not always be more expensive.
• Option B: Non - renewable (e.g., oil spills harm wildlife) are generally more harmful than many renewables (e.g., solar, wind with proper siting).
• Option C: Renewable energy (e.g., advanced solar panel tech, new wind turbine designs) often requires new tech. Non - renewable (e.g., traditional coal mining and combustion) may not always need more new tech.
• Option D: By definition, non - renewable (e.g., fossil fuels formed over millions of years) take a much longer time to replenish compared to renewable (e.g., solar, wind, biomass which can be replenished in a human - relevant time frame).

Answer:

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