The material mentions two categories of energy sources. Which option correctly identifies them?

• A. Solar and wind
• B. Renewable and non-renewable
• C. Fossil and renewable
• D. Kinetic and potential

Answer: (B)

Two broad categories describe energy sources: those that can be replenished within a human lifetime and those that cannot. Renewable energy sources—such as solar, wind, hydro, biomass, and geothermal—provide energy from natural processes that continually replenish, so they are sustainable over the long term. Non-renewable energy sources come from finite reserves that deplete as we use them, like fossil fuels (coal, oil, natural gas) and often nuclear fuel, which are not readily replenished on human timescales. That distinction makes the grouping renewable and non-renewable the best fit for describing energy sources overall. The other options point to specific sources, energy forms, or a mix that doesn’t capture the standard two-category framework.
