How long will the sun produce the solar energy?

The sun has produced energy for many millions of years and will do so for many millions more. It is estimated that there is still enough hydrogen in the sun's core to last another 4.5 billion years. Solar energy as we refer to it is the solar radiation (light and heat) that reaches the earth. Every day the sun radiates enormous amounts of heat and light energy. The planet and the atmosphere absorb some of this energy with the remainder being reflected back out into space.
