Reading the news this week is like "It works out slightly cheaper to boil water on a gas hob than using an electric kettle - as long as you boil only the amount you need, use a lid and switch off the hob as soon as it has boiled."
Great. Sound. Got it. I’ll make my coffee in a pan and measure the amount first.
"Wash clothes at 30° and ditch the tumble dryer." Fab. Ok. So I just throw it all on the radiators instead now?
