As far as energy use we’re it’s such a tiny amount of energy compared to any given appliance.
I think others are concerned with a trend that extrapolates to something insane power consumption where power use grows exponentially to megawatts where clock speed is growing asompotically to say 10ghz
Back in the Amiga era, I inverted the PSU fan of a very loaded 2000 (lots of memory, SCSI, Video Toaster, etc) and piped in the output of an air-conditioner directly to it (with a little bit of epoxy sculpting). It stopped crashing and worked happy for a long time until being replaced by a boring Windows box running NT.
Tbh I like it in winter, warms my living room up nicely. In summer I just run my aircons more, but I also usually game less because the weather is nice.
