None. Gravity, or a gravitational field, does not of itself possess energy.

If you want to get into basics, the source of the energy - of solar power -
is the conversion of matter into energy according to the Einstein equation
during the various fusion processes occuring in the Sun. Gravity forces the
nucleons close enough together to react, the strong nuclear force does the
rest. However, neither gravity nor the strong force are the source of the
energy.


I guess it's those vibrating strings?

The matter that becomes energy in the Sun, if we are going to REALLY go
back, used to be energy right? Best we can tell, at the beginning of this
whole mess, there was no matter at all. Everything was packed so densely
that matter could not exist at all, just energy.

So I guess, we are running off the incredible amount of energy it took to
compact everything into the singularity that "exploded" as the Big Bang.

I guess this is where (insert your favorite diety) comes in. But can't
gravity do that?
