Which energy resource is renewable and commonly used to generate electricity but can replenish over time?

• A. Solar Energy
• B. Coal
• C. Oil
• D. Natural Gas

Answer: (D)

Renewable energy resources can be replenished naturally, and solar energy is a prime example because the sun continually provides power. Electricity from solar energy is produced using photovoltaic cells that convert sunlight directly into electrical current, or by solar-thermal systems that use the sun’s heat to run turbines. Since the sun shines every day (on average) and will for a long time, solar energy can replenish over time, making it a sustainable way to generate electricity. In contrast, coal, oil, and natural gas come from ancient organic material and are finite, so they aren’t renewable. Therefore, the energy resource that is renewable and commonly used to generate electricity while replenishing over time is solar energy.
