Which of the following is NOT considered a non-renewable resource?

Solar energy is not considered a non-renewable resource because it is derived from the sun's rays, which are constantly available and replenished. Unlike coal, natural gas, and oil—fossil fuels that take millions of years to form and are finite in supply—solar energy can be harnessed continuously as long as the sun shines. This characteristic makes solar energy a renewable resource, contrasting with the non-renewable resources that can be depleted over time and require significant geological processes to regenerate. Understanding this distinction is crucial in discussions about sustainability and energy use.
