Question: how much electricity does an electric oven use?
Answer: A typical electric oven runs on 2,500 to 5,000 watts (depending on the model, age and mode it's in) and set to 350° uses an average 2 kilowatt hours (kWh) of energy for 60 minutes of cooking time. A 1,200-watt toaster oven set to 450° for 50 minutes uses only 0.9 kWh, according to BC Hydro.
