This is a great point, particularly considering here in the US we've lost the ability to claim deductions on a home office if we're a company employee, as of 2018.

I've worked remotely for a long time, and have accepted the reality of increased electric bills, but I'm sure this was a surprise to some.

There may be exceptions in hot climates with AC, but I strongly suspect that the far bigger cost for people is now those who need an additional room for work rather than those with a somewhat higher utility bill or footing the cost of a new desk chair.

Continual draw for external monitors and PCs adds up. Anecdotal, but I know quite a few devs in this area had a pretty easy time fitting a desk into their master bedroom when needed.
