Energy's Origin. The sun, like all activestars, is a massive hydrogen-burning furnace producing huge amounts of light, heat and radiation, about 4 x 10^26 watts every second. ... The process by which the sun creates andreleases energy is called fusion.

Heya!!!!
Here is the answer to your question...
The stellar core is full of exothermic fusion reactions that release enormous amounts of energy, which in turn keep the sun from collapsing in on itself. The enormous gravitational force due to the extreme amount of mass of the sun is responsible for creating the conditions (high temperature, extremely high pressures) necessary for hydrogen atoms to overcome the coulomb barrier (two positive charges repel each other) and fuse to make Helium, releasing energy in the process. A portion of that energy created is radiated from the sun and travels long distances, and reaches all planets in the solar system. Eventually, when hydrogen runs out in our sun, the conditions will become suitable for large scale fusion of helium. Large stars can even get hot enough to eventually fuse heavier elements, though the energy released from the fusion reactions is highest with Hydrogen, so the stars burn heavier elements faster to compensate for the lower energy yield.
Hope it helps...
