Which is true for solar power? A. It is not a renewable resource. B. It has a limited supply. C. It is a clean energy source. D. It is useful for all locations on earth.

D is not true because there is only sunlight during the daytime and when it is daytime in one place on the Earth, it is nighttime somewhere else.

A is not true because no fuel is being wasted by harvesting sunlight that is coming towards us no matter what. B is also not true because no matter how much of that sunlight you use, it's not using up any of the actual Sun.

C is the correct answer. Sunlight is a clean energy source as there aren't any byproducts from harvesting it. (Whereas something like coal would release gases such as carbon dioxide)
