It's kind of impressive to increase household electricity consumption by 10% by just switching one CPU.

I run a 13900T unlocked (meaning, it runs 35W TDP at idle, 1.1ghz, but is allowed to peak to 210W for up to a minute, with the hugest Noctua D14something I could fit on it). It runs at ~29c idle, peaks to 80ish celsius at 210W (~4.5ghz over all cores - songle core peaking to 5.3ghz).

For a time I ran it 24/7 without suspend. It's a big system, lots of disks, expansion cards, etc. If it doesn't suspend, and doesn't do anything remarkable, it uses about ~5kWh per day. Needless to say, it suspends after 60 minutes now (my daily energy usage went from ~9 to ~4 kWh).

I guess the author runs it at high load for long times, not only for the benchmarks to write this blog post. And less than 10 kWh is a low starting point, many households would be much higher.

That vastly depends where you live and what you use electricity for. Most of Europe for example uses much less energy [1], although that will probably change as heat pumps are becoming more and more widespread.

		I think this is just consumption divided by population, so very easily influenced by e.g. having little population and many data centers: I doubt the average person in Iceland is spending 10k+ bucks on electricity annually.

The amount of power this is using is roughly the same as it takes my car to do my short commute to work
