Nuclear fusion.

Explanation:

The mass of the star and its gravity creates a lot of heat and pressure in the center, which can fuse elements all the way up to iron (depending on the size of the star) into heavier ones. The energy produced from this pushes outwards, keeps the star from collapsing in on itself, and eventually makes its way out of the star as light and heat.
