Most of the sources of energy we use, represent stored solar energy. Which of the following is NOT ultimately derived from the sun’s energy?

Detailed Solution:

The correct answer is “Nuclear energy”.

Nuclear energy is not ultimately derived from the Sun's energy. While it's true that the Sun's heat and pressure are responsible for the creation of elements like uranium and thorium, the energy released in nuclear reactions comes from the splitting of atomic nuclei, a process that is independent of ongoing solar radiation.
