Utterly false:
PS5: 5M
PS4: 115M
PS3: 88M
PS2: 155M
Xbox/. Xbox 360: 106M
Xbox One: 51M
Wii/Wii U: 114M
Even with the above, I'm leaving off several hundred million consoles between the 1st-gen PS and the older Nintendo units, simply because their present footprint and/or power consumption is too low to count significantly. As for your belief that anything but the most recent console generation is "sitting around collecting dust", you are seriously underestimating the percentage of these units that are resold when the original owner upgrades. In North America, that percentage is low, but in Asia and Eastern Europe in particular, it tops 75+%.
Those numbers are pretty much exactly what I wrote. Around 170 million units per generation between Microsoft and Sony combined, with overlap and replaced hardware likely bringing the number of households down closer to 150 million. It's weird that you would combine Xbox and Xbox 360 numbers together though, since those were two completely different generations of consoles, with the original not selling particularly well, and the vast majority of sales going to the PS2 that generation. The same goes for the Wii combined with the Wii U. I guess that fits with the trend of manipulating numbers to make them appear higher than they really are though. : P
And again, the Wii draws less than 15 watts when gaming, so I'm not sure why you included it. I'm specifically referring to hardware that is capable of drawing something vaguely in the vicinity of that 200 watts you suggested. And that's still a fair amount higher than what many of these devices use.
I don't see evidence suggesting that a large portion of those older consoles are still seeing regular daily use averaging over 800 hours a year either. You are basing calculations on guesswork that seems a bit out of touch. The reason I pointed these things out is because you were calling someone out for making up numbers, but then did the same yourself under the guise of having data to back them up. It's not that I missed your point, just that you are using bad data to support your point.
You still miss the point. Use whatever reasonable estimates you wish: you'll still reach an energy usage figure comparable to that used by mining. And each and every joule of it wasted for no good purpose whatsoever, save personal gratification. I'm not a big fan of crypto-currency (in fact I've spent countless posts exposing its flaws) but the fact remains it can at least claim some socially-useful benefit. Gaming has none, no matter how shrilly you scream otherwise. And yes, I myself average more than that 832 hrs/year gaming. I don't allow that to excuse absurdly puerile justifications for my hobby, however.
And also, your point is kind of questionable. Gaming has "no socially-useful benefit" but cryptocurrency does? Cryptocurrencies are designed primarily as a means of making their creators and earliest adopters/investors money, and little else. As currencies, they have proven to be hugely unstable, with their value based mostly on speculation and market manipulation. Compare that to something like the dollar, or the euro, that tend to remain relatively stable from one year to the next, providing some amount of confidence in their value. The massive energy waste of cryptocurrency compared to those other monetary systems just makes the whole thing worse.
Gaming has been shown to provide many benefits, being a form of entertainment, and in many cases a means of socialization. As far as "wasting energy" goes, there are many other forms of entertainment and socialization that use more. Just driving somewhere nearby will tend to use more energy than a lengthy gaming session. And really, having a person be able to buy a single graphics card for gaming (or something like content creation) just seems like a less greedy use of the hardware than having someone buy up as many cards as they can get their hands on for either burning through power for the sole use of generating a currency of questionable usefulness, or for reselling to those who are at prices that put them out of the reach of others.
