Households who primarily cook with an oven could save up to £604 a year by using more energy-efficient cooking method.
Researchers calculated the energy consumption of 83 appliances and compared the running costs with the cheapest alternative. They found that that most energy-intensive cooking appliance is an electric oven, which typically costs 87p per day to run or £316 a year.
However a microwave costs just 8p per day - representing a potential saving of £287 per year. An air fryer would cost just £52 a year, a saving of £264. The research by energy supplier Utilita also looked at how cooking methods can slash power consumption by up to 90% and save an additional £317 a year.
