Which of the following is an example of a renewable energy source?

Solar energy is characterized as a renewable energy source because it is derived from the sun, which emits a continuous supply of energy that can be harnessed and utilized without depleting the resource itself. The sun is expected to continue producing energy for billions of years, providing a sustainable and clean alternative to fossil fuels.

In contrast, coal and natural gas are fossil fuels formed from the remains of ancient organisms and are limited in availability, making them non-renewable. Their extraction and combustion also contribute to environmental pollution and greenhouse gas emissions. Nuclear energy, while not a fossil fuel, relies on finite resources such as uranium, which are mined and processed, thus it falls into the category of non-renewable energy sources despite producing low greenhouse gas emissions during operation. Solar energy stands out for its ability to replenish itself naturally and sustainably.
