Re: WFH is ok, but the bills aren't
Electric is more than you think - pc on all day, two monitors, all the lights, making tea etc. The office was air conditioned - if I run an air con unit here the cost would be excessive. This winter I'm using a lot more heating than last because it needs to be on a lot more of the day.
As for fuel and rubber - that depends on your commute. My costs were relatively low and don't offset the increased costs from WFH.
