a refrigerator, ironing clothes, heating or AC consume at least 3-5 times as much (assuming they are latest generations, which usually are not, and the CPU is running full throttle all the time, which is not usually the case). I don't think that a Xeon is a real threat in the context of environmental damages. Switching to newer CPUs would save a few kWs per year, the difference is negligible in the grand scheme of things.

My fridge uses practically no energy for 23.5 hours a day, and for those 30 minutes it's active, it's a heat pump which tends to be incredibly efficient. Many parts of the world (huge parts of Europe for example) don't need or have AC, and for 9 months of the year I don't need heating in my home - despite living in a 130 year old stone building in Scotland. Short of the 3kw electric kettle I have, my workstation is the single most energy intense appliance in my house, and it's used for 8 hours a day, 5 days a week, 47 weeks a year.

  on average a modern refrigerator consumes about 2kw/day most of them are 10 years old and are on 24 hours a day, everyday. and in many parts of the western World they use very big, very power hungry ones, coupled with an external freezer, for long term storage. > Many parts of the world (huge parts of Europe for example) I'm in Europe, in many parts of Europe we do need AC. Ice age has not returned... yet it's 30 degrees right now here, at 2 am. And I'm a thousand kms north from truly hot parts of my country. It was 31 degrees in Berlin today, and July has just started. > Short of the 3kw electric kettle I have, my workstation is the single most energy intense appliance Your workstation consumes around less than 1Kw/day (even a ten years ago CPU is less than 100 watts/hour idle, which is most of the job it usually does), 1kw it's one hour of ironing, less than an hour with the AC on (a small one, I hear in US they suck up to 3.5 kW/h, average houses are bigger) or of a washing machine (cold water) and 40 minutes of a dryer (a low power program. they can go up to more than 2kw/hour for home appliances and up to 6kw for industrial ones). on average 40-50% of the energy budget for a data center is spent on cooling. and they are very efficient at doing it at scale. maybe, just maybe, if energy efficiency is so important, we could start by reducing useless waste: crypto mining or videogames that need a 350 watts GPU to run.
