A human brain consumes approximately 12 Watts. If 10^15 operations per second took 12 watts, 10^80 operations per second would take 10^39 W, which is several orders of magnitude beyond what all the stars in the visible universe combined produce.
Using all of the Sun's power at brain level energy efficiency would be equivalent to 10^40 operations per second. Still a quintillion times the combined brainpower of all humans currently alive.
