Which of the following best describes renewable energy?

Renewable energy is best defined as energy that is derived from natural processes that are continuously replenished. This means that the sources of renewable energy, such as solar, wind, hydroelectric, and geothermal, can be replenished naturally over a short period of time. For example, sunlight is consistently available during the day, wind is generated by atmospheric changes, and water cycles continuously through the environment. Therefore, renewable energy sources are sustainable and can be used repeatedly without the risk of depletion within human time scales.

The other options do not accurately reflect the nature of renewable energy. The first option describes sources that cannot be replenished, which contradicts the very definition of renewable energy. The second choice refers to finite and exhaustible sources, which aligns more with fossil fuels and non-renewable energy sources. The last option indicates a reliance on fossil fuels, which is the opposite of what renewable energy represents. By focusing on energy sources that are continuously replenished, the distinction of renewable energy becomes clear and highlights its sustainability benefits for the environment and future energy needs.
