Testing has found that washing at 30°C rather than 40°C uses 38% less energy. This could cut your energy bills by up to £23 a year, based on four washes a week. And if we all made this change, the UK could reduce our CO2 footprint by the same amount as taking 400,000 cars off the road. Going down to 20°C reduces energy use by 62% – or the same as taking 634,000 cars off the road. If the past few months have taught us anything, it’s that if we can support each other and work together, we can make a real difference. And you’d be surprised how much impact a seemingly small change can make.
