Boy, the NRDC's going to have a fit when they start looking at the computers with kilowatt power supplies with graphics cards that draw over 300W and CPUs that draw over 100W while gaming.
I agree with the NRDC though, to have the default power mode set to the lowest one on consumer gaming consoles just because average people won't know to switch it to low power mode and the fact that there are so many consoles in households.
BTW I'm one of those energy hogs that runs his Xbox One so that upgrades can happen in the background.
