On August 26, the wholesale price of a kilowatt hour of electricity broke a new record, reaching €1,000 compared to €86 in the same period a year ago. Here are some tips to save money.
1- Make sure your home is well insulated
In a house, heating is the thing that consumes the most energy. According to figures from the Environment and Energy Management Agency (ADEME), the average annual consumption of heating electricity in a house is around 4 312 kilowatt hours (kWh). For Florence Clément, head of information at ADEME, it is in housing insulation that efforts should be focused. “Few people know this, but there is a public energy renewal service across the country called France Renov.” The specialist advises to make a free appointment with a technical advisor near you. Its role is to help and support those who want to insulate their homes. “We arrive with photos of his accommodation, invoices and above all we do not start work without making an appointment, at the risk of losing the very important financial aid.”
2-Reduce your hot water consumption
After heating, the consumption of an electric hot water tank is the second largest electricity consumption in a house. According to ADEME, a 200 liter tank consumes an average of 1 676 kWh per year. That is an annual cost of €285 with an electricity price of €0.1740/kWh.
According to Florence Clément, there are many solutions to consume less hot water. “The first reflex is to start by checking the temperature at which the tank heats up. Heating the water to 50 degrees is more than enough. Then, you can install water aerators in the faucets. This will allow you to limit your water consumption. general and therefore of hot water. You can buy it in all DIY stores for less than 10 €.”
3- Defrost in the freezer
After heating and hot water, the third item of electricity consumption is taken by electrical appliances. The appliances that consume the most electricity are those that need to remain stationary, such as refrigerators and freezers. For Pascal Jacquemin, manager of home appliance repair company SAV Somatelect in Witry-les-Reims, the advice is simple: “Avoid it freezing! You don’t have to wait for a heavy layer of frost to settle down to start defrosting. The ideal is to do it every 3 months.” It should be noted that, over the years, a new technology has been offered by manufacturers : the no cold. This is an automatic defrosting system offered on some newer models. And here too, like the hot water tank, you need to adjust the temperature of your freezer. “To ensure that the food is frozen to the core, a temperature of -18 degrees is sufficient”, added Pascal Jacquemin.
4-Use an eco program in the dishwasher and washing machine
To save money, sometimes it is enough to take a few minutes to read the instructions for use of appliances that run on electricity. In the kitchen, Pascal Jacquemin recommends using the dishwasher’s eco mode. “In fact, it takes longer, a cycle of 3 hours instead of 1h30. But the intensity is not so important so that we waste less energy.” The advice also applies to the washing machine, where you can use another reflex: wash your clothes at a low temperature. “In most cases, Washing at 30 degrees is more than enough“, added Mr. Jacquemin.
5-Unplug electrical appliances
In recent days, there have been many calls to remove electrical appliances such as internet boxes or televisions. However, for Florence Clément, we must remain cautious of these reflexes. “In fact, it will allow you to control your energy bill, but it will not weigh heavily on the total electricity bill.” Therefore, it is estimated that removing the internet box at night will save money 30 € a year, ie 2.5 € per month. “These are small movements that, at the scale of a household, are not very representative, but if we increase the number of households in a territory, it will reduce the total consumption of electricity.”
