While the story is very positive and encouraging -- Unfortunately an unintended side consequence of these kinds of efforts (unless you're very conscientious about maintaining the correct incentives, generally through pricing) is sometimes that the gains in energy efficiency and savings are clawed back by an increase in overall energy consumption because it's gotten effectively cheaper to operate for the same number of compute cycles. Just like with energy efficient LED light bulbs, although the overall energy use goes down, often it doesn't go down as much as it could have ideally, because people start lighting places that didn't have light before, because it's gotten so much more affordable to do so! Or like when you add highway lane capacity, traffic gets worse... Or in this case, the Google video engineers come up with new useless filters and resolutions to occupy the newly freed-up compute capacity. Just something to be aware of. The people who do this have to monitor and put in place controls so that the outcome is what they intended. Otherwise people are more clever than you think. |

LEDS have to be one of the worst possible example for claims of induced demand as a bad thing given that the efficency gains outstripped proliferation of additional always on devices and a cellphone per person.
While Induced Demand may exist it too has its saturating limits of diminished returns.
