Beyond the recommendation of energy stability requested by Emmanuel Macron because of the crisis approaching this winter, is it useful to take small actions every day to lower your bill?
The energy crisis, the purchasing power crisis… the French are worried about small ecological movements help protect the planet, save energy and save money.
Or at least, they are asked to apply it. But is it really worth putting in some effort?
To answer this question, simply compare and calculate the savings at the end of the year.
Eco-gestures to consider
Big budget for the Frenchaccording to Ademe, the Environment and Energy Management Agency, energy expenditure represents a large part of household costs.
“The household budget allocated for energy remains significant and may increase in the coming years with rising energy prices.” Housing accounts for 59% of these expenses. In detail, heating represents 66% of a household’s energy consumption. appliances (17 %), hot water (11%) and cooking (5%).
The institution thus presents savings that seem simple to make, just by using a few daily practices.
As lowering your heating by 1°C corresponds to a 7% reduction in consumption, washing clothes at 30°C uses three times less energy than washing at 90°C, close to your shutters at night up to 60% heat loss through the windows. , covering pots saves 25% or even using the dishwasher’s eco program represents 45% less electricity compared to the intensive program.
A simulator set up by EDF
To find their way, EDF has set up a simulator so that each individual can list their equipment and save energy with some advice given if needed.
A tool that can be practical and useful.
The profit of every eco-gesture
To calculate each eco-gesture, the The list may not be complete and it should be common. The use of each equipment as well as its power and its age vmoving from one home to another.
But this proposed calculation makes it possible to see if there is real savings or not.
Each one power consumption calculated as follows: the number of hours of operation X the number of days of operation x the power of the device in watts / 1,000, as specified on the Engie site.
Then just do the calculation of the average price per kWh estimated in France at €0.174 in 2022 for the basic regulated tariff of EDF according to the supplier-electricity website.
1. Internet and Wi-Fi box
An ADSL internet box consumes 280 kWh per year and a fiber internet box between 150 and 300 kWh per year, as specified on the Choisir site.
which is equal to more than 48 euros per year for an ADSL box and between 26 and 52 euros per year for the fiber box.
So if we turn off this type of equipment at night or during the day when we are not using it, we can say that even half the time, the bill is halved. Become one savings of 24 euros per year for an ADSL box and savings between 13 and 26 euros per year for a fiber box.
A LED bulb lit about three hours a day consumption on average throughout the year 9.855 kWh, which is equivalent to 2 euros. A classic light bulb also lit for three hours a day consumes on average over the year 65.7 kWh, which is equivalent to about 12 euros per year.
Replacing light bulbs with LEDs can be done that way saving 10 euros per year for each light bulb used three hours a day.

3. Phone charger
According to measurements made by Engie, a A power strip with six chargers connected “empty” consumes 2.6 kWh every year. So the cost is derisory, thus amount to less than 50 cents per year.

As specified in Que Choisir, a European directive that came into force in 2010, limits the power of standby devices to 0.5 W. So we can think that a toaster turned off thus consuming 4.38 kWhwhich is equal to a annual cost of less than 1 euroa small number.
On the other hand, a lit toaster consumes between 500 and 1,600 watts depending on the model. But throughout the year, it should be used, on average for a family of four, for 30 minutes per week, 26 hours. Therefore the consumption increases between 13 Kwh and 42 Kwh per year ie a cost between 2.5 euros and 7.5 euros.
Like the toaster, we can think that the power of the device on standby is 0.5 W even if other devices are connected to the internet, so some televisions can reach 6 W.
What went up annual standby consumption between 4.38 Kwh (less than 1 euro) and 52.5 kWh (Less than 10 euros).
For information, the consumption of a TV on depending on the model. Devices consume between 70 W for LD screens to 400 W for plasma screens.
What makes a consume one hour a day on average over the year between 26 KWH (about 5 euros) and 146 kWh (ie about 25 euros).
Each additional hour therefore increases the bill. The eco-gesture can also be done by reducing your time in front of the television.
6. Warming up
Ademe explained on its website that lower the temperature by one degree will reduce the annual consumption of individuals and therefore the bill, 5 to 10%.
The ideal temperature can also be 19 ° C in living rooms and 17 ° C in bedrooms.

As determined on the Engie site, there is an average heating power calculated based on a standard height of 2.5 meters under the ceiling. He understood between 70 and 100 watts per square meter. This is actually a estimate, because the required power varies for several reasons. : the volume, the insulation, the geographical location of your accommodation, but also the preferences in terms of heating.
For a surface of 15 m², the average power required is between 1000 W and 1500 W, for 20 m², between 1,400 W and 2,000 W, for 30 m² between 2100 W and 3000 W and for 40 m² between 2800 W and 4000 W.
If we take a 20 m² room for example by heating it five hours in five months, consumption increases annually for a room between 1,050 Kwh (ie 182 euros) and 1,500 Kwh (ie 261 euros).
If by lowering 1 °C we get a drop of 5 to 10% the economy which can be for a heated room increase between 10 euros and 25 euros.
As the French heat an average of 4 rooms, the savings are multiplied by 4 for an invoice that is also multiplied by 4. The savings can easily reach a hundred euros a year.
The consumption of a refrigerator is far from trivial. In general, the refrigerator consumption equal to approx 200 to 500 kWh/year. So it costs a lot between 35 euros per year and 87 euros.
Of course, consumption varies according to the model, capacity of the device, age or even the state of maintenance of the device.
To save money, it is necessary to adopt the correct temperature, between 4°C and 5°C, for the refrigerator. And minus 18°C for the freezer, but also to get a new appliance, to put your refrigerator and to leave the door of the appliance tightly closed and well sealed.
The right actions can be possible to save up to 30%, according to Engie, ie a saving between 10 and 26 euros per year.
8. Washing machine
In general, the power of a washing machine is around 2500 to 3000 W. So it depends on the number of machines produced each year.
If we count approx 150 machines a year (smaller than every day) with a two hour average cycleconsumption is all around 750kWh to 900kWh or annual cost between 130 euros and 156 euros.
Using “low temperature” or “eco” programs saves money.
Knowing that washing at 30°C consumes 3 times less energy than a wash at 90°C and that a cold wash consumes 2 times less than a wash at 40°C. the The savings can easily amount to between 50 euros and 100 euros.
In general, the power a dishwasher included between 500 and 1,500 watts. Based on two hours of use per day, the annual consumption varies from 365 kWh (63 euros) and 1,095 kWh (190 euros).
It is important to fill it as much as possible to launch a few cycles a week
Then choosing a class A+++ dishwasher over a class A+ dishwasher allows you reduce appliance consumption by 20%and up to 43% for Class C devices, as reported by HelloWatt.
Become one economy possible from 12 euros to 80 euros.
10. Hot water tank
According to the Hellowatt site, the power consumption of a hot water tank or cumulus depends mainly on its capacity and its power.
the average consumption of a water heater per year depending on the composition of the focus and the size of the balloon 848 kWh (147 euros) for a 50 l tank, 1,697 kWH (295 euros) for a 100 l tank and on 3,393 kWh (590 euros) for a 150 l tank.
Heat a liter of water to 1°C. It is 1.162 kWh.
The temperature of cold water that is considered ideal is 15°C and hot water is ideally located at 55°C.
So if the temperature is 60°C, just lower it by 5°C. In addition to using the device during off-peak hours, turning off the water heater when on vacation…
Savings depending on the operation can reach 30%, ie a savings between 45 euros and 177 euros.
So by summarizing all the eco-gestures proposed it will be possible to save money quickly up to 450 euros per year (in a wide range).
If in addition some devices work at night time, the profit becomes more interesting. On good terms…
