I have a gas oven but an electric one in the garage… will it be cheaper for me to have electric than gas?
Gas will always be cheaper to run. They use gas to make electricity so per unit of energy the gas will be cheaper. However if your gas oven is poorly insulated and door doesnt seal well then I guess you need to take this into account but as far as cheapness the gas will be cheaper.
I cook professionally and to be honest both types have their merits and disadvantages – I prefer to use an electric oven but a gas hob at home – gas hob is more controllable and instantly changeable, the electric oven is more stable and even.
Make sure your gas oven is well maintained and the burner burns evenly check the manual.
