We've known the Wii U uses about 33w to play games since launch. It's the pound-for-pound king. An incredible achievement that is nearly completely ignored despite, in the ecological sense, being more cutting edge than any other console ever created. (We often gauge technological advancement in terms of raw power, but many of the most practical and useful innovations allow similar performance at drastically reduced cost).

@unrandomsam It's true that energy storage is currently impractical; however, the issue is demand. As power consumption increases with each generation, the electricity required to facilitate our gaming demands will increase. Meaning more fuel and/or power plants need to be utilized. Since that energy cannot be stored, the grid will have to adapt to the highest levels of demand. (Like hot summers with, say, tens of millions of XB1 owners heavily gaming, "snapping", and accessing gigantic (cloud) server farms while cranking up the air conditioners, sound systems, and whatever else mildly enhances their sheltered experience.)

It's easy to say rely more on Hydro (a shockingly small percentage of US energy production) or Nuclear, but those are not necessarily infallible solutions. Great American rivers such as the Colorado River have been strangled by dams from massive waterways into literal streams. Nuclear waste cannot be disposed of and so in the USA we have massive leaking underground containment fields that cost hundreds of billions of dollars to provide ineffective, polluting storage. Considering the lengthy half-lifes of the radioactive materials, this is a major issue with no solution and intense cost to the environment.

Moreover, the security, stability, and sustainability of our current Nuclear power plants are in doubt. We haven't built a new power plant in this country in decades and many of the plants in operation are in disarray, quickly built on risky, threatened, and incompatible locations chosen for convenience and price rather than long-term suitability. The ability to withstand natural disasters is a serious, unproven issue. I live about 60 miles from a nuclear power plant that is located in the northern extent of Tornado Alley. It's widely accepted in this area that one unlucky tornado path could leave us all in a nuclear fallout. Even worse, it's built upon a 500 year dike that was breached and very nearly failed several years ago. And this plant is considered safe. You would not believe some of the precarious situations in which plants are operating (such as directly above San Andreas fault).

Constructing sentences is a triviality, but there are no easy answers for the demands of modern society.
