Risks of power cuts: which appliances consume the most at home?

Instead, use the hotplates or the microwave. Indeed, cooking 500 g of potatoes in the oven consumes 10 times more energy than cooking them in a pan on an induction hob. For example: a 2,000 W oven, operating for 1 hour, consumes 0.8 kWh; a 1,500 W microwave, operating for 15 minutes on maximum power, consumes 0.3 kWh; an induction hob, operating for 30 minutes, consumes 0.35 kWh.

In addition, do not choose the maximum power of the hotplates which can then consume up to 3000 W for several minutes (it is often not necessary to boil at a rolling boil throughout cooking). Also remember to shorten the cooking time by covering the pans. Indeed, boiling 3 liters of water on a ceramic hob without covering the pan consumes 0.4 kWh. By covering the pot, 0.3 kWh is consumed, i.e. an energy saving of 25%.

Other tips, do not preheat the oven before starting to bake a cake; you save 10% of electricity on the cooking cycle. Turn off the oven or hot plate (vitroceramic, cast iron) 5 to 10 minutes before the end of cooking. And prefer the convection oven mode, because it cooks food faster.
