Green?

If we go with DT's first sim and add the four extra diodes to save the 20ma while the part is running. I wonder what the extra "green" cost of manufacturing, shipping and all the rest for the diodes and the possible extra board space for the part all adds up to.

I would guess, just a guess, the energy would be more than 20 ma at 5 volts. And what would it cost to do the study to find out?
