An example of a renewable resource is:

Solar energy is considered a renewable resource because it is harnessed from the sun, which is a powerful and abundant source of energy that is replenished constantly as it is generated through nuclear fusion in the sun's core. Unlike fossil fuels, such as coal, oil, and natural gas, which take millions of years to form and are finite resources, solar energy is sustainable and can be utilized for various applications, such as electricity generation, heating, and powering vehicles, without depleting the resource.

The other options—coal, oil, and natural gas—are classified as non-renewable resources. These fossil fuels are formed from the remains of ancient plants and animals over geological time scales and are being depleted faster than they can naturally regenerate. Their extraction and use also contribute to environmental challenges, including greenhouse gas emissions and habitat destruction.
