I'd do a tip saying that you can best run your washing machine in off hours since evening out energy usage is better for the environment and that always doing that is even better since predictability of energy usage is even more important, but I'm afraid someone would come by and cancels me for using a washing machine instead of doing the laundry with a washing board. Only for that person to be cancelled for doing any laundry at all, since it's best to just keep wearing your smelly clothes. So I won't. I'll leave this here, do with it whatever you want.
