Really care to do a back of an envelope calculation for the distance travelled (ignoring atmospheric resistance) in order for a typical rain drop (volume 0.05ml) to release 9x10^12 Joules.

Then try calculating the energy incorporating atmospheric resistance where the resultant force on the rain drop is no longer conservative.
This latter calculation will give a much more realistic value.

I leave it to you as an exercise.
