Question: how many joules of energy does the sun produce?
Answer: The sun produces 1.23 x 10 ^ 35 Joules of energy in one year. To compare, a nuclear weapon only gives off 4.18 x 10 ^ 15 Joules of energy, which is less energy than the Sun produces in ONE SECOND. All this heat energy is what powers life here on Earth, and is strong enough to be felt 150 million kilometers away.
