With more time spent at home—especially during remote work—your energy bills can climb. While computers and devices use minimal power, cooking appliances like ovens (around 1,000 kWh annually) and electric hobs (500-1,000 kWh) add up significantly, as does a fuller fridge running more efficiently than an empty one.

Drawing from ADEME studies and energy experts, here are practical, proven tips to lower consumption effectively.
ADEME research shows major heat losses in older homes: 20-25% from walls, 25-30% from roofs, and 10-15% from windows. Pre-1974 buildings often lack thermal standards. Start with a professional energy performance diagnosis (DPE) to assess consumption and pinpoint insulation issues. While upgrades cost upfront, they pay off quickly through bill savings. Plus, French government aids like MaPrimeRénov, CITE tax credit, ANAH grants, and the "Energy saving boost" scheme make renovations affordable.
Electric heating accounts for about one-third of household energy use. Yet many overheat homes to 20°C+ due to habits from offices or shops. ADEME recommends 19°C in living areas and 16°C in bedrooms—excess heat disrupts sleep, dries airways, and spikes headaches. Use a humidifier if needed.
Ventilate daily for 5-10 minutes (turn off radiators first to avoid heating the outdoors). Lower by 1°C when away to save 5-7%. Never fully switch off—reheating consumes more. Embrace smart thermostats controllable via app for optimal efficiency and convenience.
Hot water represents 15% of energy costs. Set your tank to 50-55°C for efficiency—higher risks burns (needing cold water dilution); lower allows bacteria and scale buildup. Scale alone boosts consumption: 1 mm adds 8%, 10 mm up to 50%. Schedule regular checks, especially in hard-water areas.
Shower over bath, turn off taps while brushing or washing dishes—these basics help. Run dishwashers and washers full-load only, using eco modes for optimal water use. Toilets use nearly one-third of home water—switch to low-flow models (4.5L vs. 6L flush). Install eco showerheads for regulated flow and comfort. Mixer taps save water by blending hot/cold instantly.
Standby mode on TVs, computers, printers, routers, and chargers consumes over 10% of home energy—equivalent to a nuclear plant nationwide. In winter, increased home use amplifies this. Use power strips: switch off when leaving or sleeping. Programmable sockets (€10-25) automate on/off for extra savings and screen-time control.
