What's the most energy-efficient way of cooking?
Electric ovens, whether part of a cooker or a built-in oven, are more energy-efficient than their gas counterparts. Similarly, electric induction hobs are the most efficient as they supply heat only to the pan, and not out into the kitchen; electric ceramic hobs are second best, while gas trails in third.
However, it's worth noting that, because gas is cheaper than electricity, your energy bills will be lower if you cook on gas.
Using a slow cooker is a smart choice as, although it may be on for a number of hours, heating a small space requires less energy than cooking the same kind of meal in an oven.
Microwaving cooks food quickly, so is another option for keeping cooking costs low.
A combi microwave or airfryer may also be more efficient than a standard oven for cooking small items quickly.
