I think this is sensible, because sites in the same industry should have the same energy consumption. For example a video streaming site will always use more CPU than craigslist, but that’s okay because a video streaming site is competing with other video streaming sites. But I think the industry’s solution to this has always been to just wait for the inevitable faster and faster computers that come out each year, so that the lag becomes less just by the passage of time. But that becomes a cat and mouse game because as CPU’s and network speeds get faster and storage gets cheaper, developers can get away with larger sites and slower code. case in point, nowadays you can barely browse the web with an iPhone 4, but when it first came out people weren’t waiting 30 seconds for a pageload on it. Even look at the average size of an app in the App Store now. I think facebook was 40MB when it first was released, now it’s 300MB. It’s like you have to keep getting newer and newer hardware just to keep up.
