Distinguish renewable vs non-renewable energy resources with examples.

• A. Renewable resources replenish themselves and can be used indefinitely (solar, wind, hydro, geothermal, biomass); non-renewable resources are finite (coal, oil, natural gas, uranium).
• B. Renewable resources are always cheaper than non-renewable resources.
• C. Renewable resources are replenished naturally and can be used indefinitely (solar, wind, hydro, geothermal, biomass); non-renewable resources are finite and depleted with use (coal, oil, natural gas, uranium).
• D. Renewable resources are those that are only produced in laboratories.

Answer: (C)

Renewable resources replenish naturally and can be used repeatedly because they come from ongoing natural processes. Classic examples are solar, wind, hydro, geothermal, and biomass. Non-renewable resources exist in finite amounts and are depleted as we use them; they don’t form quickly enough to replace what we consume on human timescales. Coal, oil, natural gas, and uranium are typical non-renewables. This contrast is captured by describing renewables as replenishing naturally and usable indefinitely, while non-renewables are finite and depleted with use. The other statements aren’t generally true—renewables aren’t guaranteed to be cheaper in every situation, and they aren’t produced only in laboratories.
