Why This Matters
The average European household spends over €2,500/year on energy, yet simple measures like LED lighting swaps and standby elimination can cut electricity bills by 10% or more — with payback periods under two years. Combining behavioural changes (thermostat setpoints) with technology upgrades delivers compounding savings that also reduce your CO₂ footprint by hundreds of kilograms annually.
