Is each person watching all these TVs at once Matrix style?
Even if you've got your laptop, iPhone and iPad all unlocked and playing videos while watching your TV, it's not really adding 30% of energy use compared to the 50 inch TV.
> certainly it is in public places (dentists' offices, intercity buses, airports, restaurants)
TVs in airports, bars, diners, buses, and dentists offices have been around since the 80s. The difference now is that all their CRTs are replaced — a clear energy drop. (Source: own experience, also you can watch movies from the time)
Lit billboards have been around for a long time, but instead of massive lamps, they are just LED screens. Tokyo used to be all fluorescent bulbs, now LED screens again. It might not be like for like, could maybe be an energy increase, but public-space advertising is the best argument you've got here, but I don't buy that it's a huge driver of energy growth.
> you see handwringing about it from time to time. i'd like to see it too
I've provided plenty of data to back myself, and to suggest otherwise is disingenuous. Given the amount of claims you're making without any supporting evidence, I can only think your argument is based on conviction, not fact. I'll let you have the last word here.
oh, it's quite common for different people to have different tvs on at the same time in different rooms of the same house, when previously they would have watched the same one. or for a tv to be left on displaying a screen saver. a backlit lcd uses the same amount of power whether it's showing black, blue, a static desktop, random noise, or video
i've seen many more tvs in public places in recent decades, often replacing things like flip-dot displays or printed menuboards. mcdonalds now displays their menus on a wall of tvs instead of printed on plastic, for example
it's disappointing that you've chosen to attack my integrity, but it seems to be based on a misunderstanding. i have not claimed that you have not provided data. on the contrary, i have found your data highly informative and educational. i only meant that neither of us has convincing data about total computer power consumption, and that i would like to
