The Agency for Environment and Energy Management (Ademe) has been advising on energy saving for several years. Here are some examples listed by the agency and the potential annual profits that the French, who own an average of a hundred electrical and electronic devices, can expect.
If a European regulation limits the power for a certain number of devices to 0.5 W, it remains 2 W for devices connected to the internet or data networks.
Turning off clocks can save up to 10% on electricity bills (excluding heating), but it’s also easier on appliances, says Ademe, who, however, advises leaving washing machines and dishwashers on standby, as this is often used to detect water leaks is used . For other devices, opt for power strips with switches. In addition, Ademe advises leaving computers and game consoles unplugged when not in use. As for the internet boxes, it’s better to turn them off when you don’t need them (when you go on vacation, for example). A box often stays on 24 hours a day and can use more than 200 kWh per year, which is as much as the washing machine.
Use LED lights
LED lamps consume little power and have a long service life (up to 40,000 hours), which compensates for their higher purchase price. They are the best home lighting solution provided they last more than 20,000 hours and have a good rating on the energy label. On the other hand, Ademe advises avoiding decorative LEDs that give off little light and consume electricity.
Prefer the “eco” program
The “eco” program for washing machines and dishwashers saves water and energy, even with longer programs, says Ademe. The soaking and washing time is longer, but the water is heated less; However, the heating of water consumes the most electricity. Ademe also emphasizes that the “Eco” program should not be confused with the Rapid program. Also, you should only run your washing machine and dishwasher at full capacity, because if half a load uses less water, it uses just as much electricity.
Check the energy label
Before buying a household appliance, check the energy label. Each difference in a class (A, B, … G) corresponds to around 15 to 20% energy savings.
save hot water
Saving hot water also means saving electricity if you have a hot water tank. Do not leave the mixer tap in the intermediate position: lukewarm water is used every time, while cold water is fine for washing vegetables, washing hands, rinsing sponges… Installing aerators or flow restrictors on taps saves money: you can save up to 75% water with an economical hand shower. Finally, programming the temperature between 55℃ and 60℃ is enough to limit the development of pathogenic bacteria and it limits the power consumption needed to heat the water.
