Microwaves are more energy efficient than using a hob or oven, as they heat the food directly rather than the air around it- just remember to turn it off close the door once you’re finished using it!. Slow cookers are also highly energy efficient, using just a little more energy than a traditional light bulb.
Remember to use the right size pan for the hob ring- using a small pan on a big hob ring will be wasting energy. Use a lid and turn the heat off just before the food is fully cooked to let the remaining heat finish the job. Also, give your hob a quick wipe down to ensure it works effectively.
A top-rated A+++ rated electric oven uses 60% less energy than a B rated one. While you’ll usually have to pay more for a top-rated appliance, it will save you money in the long run.
A modern energy efficient dishwasher uses less energy than washing dishes by hand. But you need to avoid pre-washing and put your machine on an eco or economy setting, which means it washes at a lower temperature for a longer period. As most energy is used heating water, this actually saves money despite taking longer.
