Last month I went a bit extreme on cutting down dishwasher and tumble dryer usage.
Pots, pans and baking trays I did by hand. Everything got hung out where possible. I only used it maybe twice in all of August. I was a bit zealous in switching stuff off, and of course I am in the office more. I managed to cut almost 50 kWh off my electricity use last month, which I am pleased about.
I have bought extra clothes horse, more pegs, lines for outside and so on. Every dry day, I will hang washing out. The tumble dryer I am starting to see as a money pit. One hour of the tumble dryer uses between 4 and 5 kWh. Or, to put it another way, costs between £1.20 and £1.50 at my new electricity rate.
