How much power is in the sun?

    The sun produces absolutely massive amounts of energy. The earth alone receives 174 Petawatts of energy (or 10^15 watts). Of this, the earth absorbs 3,850,000 Exajoules (10^18 Joules) per year. For comparison, electricity consumption in 2005 was 56.7 Exajoules. This goes to show that solar power, if properly harnessed, could easily provide all of our energy needs.

    Scientists can only approximate the power of the sun, but estimates put the total power at about 4.25 x 10^25 watts. Earth only receives about one two-billionth of this power.

    The sun has a tremendous amount of power, estimates are around 3.6 x 10^26 W. The Earth only receives about one two-billionth of the total power of the sun. In just one hour the Earth receives more power from the sun than the entire world uses in one year.
