Define renewable energy.

Renewable energy is defined as energy that comes from sources that are naturally replenished. This includes energy derived from sunlight, wind, rain, tides, waves, and geothermal heat. These sources are sustainable because they are continuously renewed by natural processes and are not depleted when used. For instance, solar panels harness sunlight, which is abundant and available universally, while wind turbines convert wind energy into electricity.

The importance of renewable energy lies in its potential to reduce dependence on finite fossil fuels, which can have detrimental effects on the environment and contribute to climate change. Unlike fossil fuel energy, which is limited and contributes to pollution and greenhouse gas emissions, renewable energy sources provide cleaner alternatives that can help mitigate environmental impacts and promote sustainability.

In contrast, other options describe energy sources that are finite, non-renewable, or limited in availability, which does not accurately reflect the nature of renewable energy. Therefore, the definition that emphasizes the natural replenishment of energy sources captures the essence of what renewable energy represents.
