Q:What takes more energy:
a.Increment a number from 0 to 2^128-1 using 2^128 increment instructions, with a CPU running at 3GHZ at exact 50 Joules/Seconds(50watt).
b.boil off the oceans on Earth.(defined as 5.58072e30 Joules)

>>10
Thats because bruteforcing isn't used. More effective techniques lower the computational complexity by many orders of magnitude.
