Electrical energy: these gadgets devour probably the most in your house

Refrigerator, washing machine, heating, air conditioning… Determining which items consume the most energy can lead to significant savings.

As energy prices skyrocket and everyone is urged to stay sober in anticipation of a harsh winter, all eyes are on everyday items. Internet box, air conditioner, TV, oven, hot water boiler… So many devices that inhabit the homes of the French and which, however, also represent significant costs.

In July, the Agency for Environmental Transition (Ademe) looked back at the electricity consumption of these different devices to determine which ones were adding the most to the bill. What to see which are the most greedy objects and to which he should pay the most attention to reduce his electricity bills.


Price rises, contract changes… The woes of customers of alternative gas and electricity suppliers

The institution relies in particular on the results of its Panel ElecDom study, which examines electricity consumption in the residential sector. The price is obtained, in turn, based on EDF’s regulated tariff, in July 2022.

Unsurprisingly, heating remains the main cost of electricity in a home, whether it is a house or apartment, as does the hot water tank. Their consumption, as well as their annual costs, are far above other devices.

The air conditioner is not to be neglected: although its consumption may vary depending on the model, it is still much more energy intensive than its alternatives: ”

A class A mobile air conditioner with a power of 2.5 kW represents over 130 euros for 1 month of use and can consume up to 2.5 times more than a stationary air conditioner and nearly 30 times more than a fan

“, emphasizes Ademe.

Possible savings on a daily basis

The kitchen also has a number of items to keep an eye on or even replace in favor of newer and more efficient appliances, whether it’s a fridge, dishwasher or freezer. Be careful with the dryer, which is particularly greedy, as well as… the TV, which spends the same even when turned off. Better unplug it or disable the power strip it works through.


“I told him that daily baths would no longer be possible”: the importance of small gestures to save energy

Another lesson: investing in new, more efficient equipment can save significant amounts each year on the devices that consume the most, according to Ademe’s calculations.

Other small gestures can also add up to significant savings in the long run. Based on the list of devices that consume the most electricity among the French, Adéme offers, for example, temperature regulation using a programmable thermostat, allowing ”

These small daily changes can lead to big savings, the company says: with good practices, energy consumption ”
