Which of the following is a renewable energy source?

Solar energy is considered a renewable energy source because it is derived from the sun, which provides an almost endless supply of energy that can be harnessed for electricity and heat. Unlike fossil fuels, which take millions of years to form and can be depleted, solar energy is constantly replenished as long as the sun is shining, making it a sustainable option for meeting energy needs.

In contrast, coal and natural gas are fossil fuels that are formed from ancient organic matter and are finite resources. Their extraction and use contribute to greenhouse gas emissions and environmental degradation. Nuclear energy, while a low-emission source of power, relies on uranium—a finite resource that is mined from the earth, and it also raises concerns related to radioactive waste disposal and potential accidents. Therefore, solar energy stands out as a truly renewable option among the choices provided.
