How much solar energy reaches the earth in a 24 hour period?

I would like to figure out how much energy from the sun reaches the earth’s surface in a 24 hour period. I’m only looking for a an approximation.
This is not for a school project. This is a personal curiosity.

  1. Approximately 10.55 zettajoules per day.
    30% of this never reaches the surface . . . so at the surface approximately 7.38 zettajoules per day.
