The statement that best explains the changes in available energy is: Energy constantly changes from one form to another.

This reflects the principle that while the total energy in the universe remains constant, it can change forms (e.g., from kinetic to potential energy, or from chemical energy to thermal energy), which affects its availability to do work.
