Every day the sun shines on our planet, another day of life is possible.  It’s easy to take for granted the sun’s energy, but this gift is the foundational source that makes our world possible.  And what’s more, all that energy is free.  As the poet Hafiz once wrote:

Even after all this time
The Sun never says to the Earth,
“You owe me.”
Look what happens with a love like that.
It lights the whole Sky.

If you want to attempt to imagine how much energy the sun shines onto the planet, try this thought experiment.
