Primary energy is energy contained in natural resources before conversion. Which is an example of a primary energy source?

Explanation:
Primary energy is energy stored in natural resources before any transformation. Coal is an example because it is a natural resource that contains chemical energy in its structure, ready to be released when burned or processed. Electricity is already energy that has been produced by converting primary sources, so it isn’t primary energy. Refined gasoline is a processed product derived from crude oil, not a raw energy source. Nuclear waste is a byproduct of energy production, not an energy source itself. So coal best fits as a primary energy source.
