Which statement about renewables is true regarding depletion?

• A. It is depleted.
• B. It is not depleted when used by humans.
• C. It becomes nonrenewable instantly.
• D. It becomes toxic.

Answer: (B)

Renewable energy sources are replenished naturally, so using them does not inherently exhaust the resource. The sun’s energy, wind, and the water cycle all provide ongoing supplies that are renewed on timescales relevant to human use, which is why renewables aren’t depleted simply by humans using them. That’s why the statement that renewables are not depleted when used by humans is the best fit. Of course, local or temporary shortages can occur if a resource is extracted faster than it can be replenished in a given area, and other risks like environmental impacts can arise from exploitation, but the basic idea remains: the energy itself is replenished, not permanently exhausted.
