Define renewable energy.

Define renewable energy.

• A. Energy from sources that can be replenished naturally (e.g., solar).
• B. Energy that cannot be used again.
• C. Energy stored in batteries only.
• D. Energy produced by burning fossil fuels.

Answer: (A)

Renewable energy means energy from sources that are naturally replenished, so they can keep providing energy over time. Examples include sunlight for solar power, wind, flowing water for hydro, geothermal heat, and biomass. Because these sources continually regenerate through natural processes, they offer a sustainable supply unlike fossil fuels, which are finite and emit CO2 when burned. The other statements mix up storage or production: energy isn’t defined by being kept in batteries, and burning fossil fuels is not renewable.
