The description may have been changed since you posted, so sorry if this is an unnecessary example to aid understanding.

Hero A, has the ability to gain strength from the sun to fuel his other powers. He also has this power.

Villain X, built a portal to a world wwith no sun at all, but has several geo-thermal vents that he uses to power his base.

Hero A, follows Villain X and slowly looses his energy reserves. He then switches his source of power from solar to geo-thermal. He now is able to gain strength from the heat of the planet he is stanging on.

He could also do so with power lines, batteries, strong wind, possibly even by consuming gasoline if he needed to. Essentially allowing for any kind of potential energy or kinetic energy to be used to refuel his reserves. If smart enough a hero with this power could possibly make it so they gain power from impact-based kinetic energy making hard punches from their opponent to power them up throughout a fight.
