Energy is produced in the sun's core. Energy is produced by hydrogen being turned into helium. Good luck!
well, there are two processes basically, fusion and fission
 
and in sun fusion takes place in sun core where helium molecules fused together to form hydrogen.

The hydrogen and helium in the Sun were produced by Big Bang nucleosynthesis, and the heavier elements were produced by stellar nucleosynthesis

hope it helped :)
