Ads have definitely added more load on electrical grids in aggregate than locally hosted and lightweight models, especially given that ads are fucking everywhere all the time. Websites, apps, the servers, even 24/7 electric billboards. I'm not worried about a few nerds using slightly more electricity sometimes for their own benefit and joy (it's still less power than gaming), as opposed to a corp that burns through power and breaks their climate pledges (Microsoft) for the benefit of their bottom line and nothing else. Corps don't get to have a monopoly on AI that was built with our data, only to have it fed back to us to pull more data and siphon more money.

So basically fuck Google and fuck ads.
