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

Solar energy is classified as a renewable energy source because it is harnessed from the sun, which is a natural and inexhaustible resource. Unlike fossil fuels such as natural gas and coal, which are finite and can deplete over time, solar energy can be continuously generated as long as the sun shines. Additionally, solar power generation does not emit greenhouse gases during operation, making it a cleaner option that significantly reduces environmental impact compared to traditional non-renewable sources.

In contrast, natural gas and coal are fossil fuels derived from ancient organic matter. Their extraction, refining, and combustion processes contribute significantly to environmental degradation and climate change. Nuclear energy, while not producing air pollution during energy generation, relies on finite resources like uranium, and produces radioactive waste that poses long-term disposal and safety challenges.
