Yeah so I was like that, until the energy prices absolutely exploded here in UK. I realized that if we go like this we'll pay £600/month just in energy costs, and that's as much as our mortgage payment - and frankly that's insane. I turned our thermostat down, grumbled and put on a jumper and wooly trousers - that alone literally halved our bill to £300/month - still insane(considering last year we were paying £100/month even in winter with heating being on pretty much all the time), but managable.
