My first electricity bill in Marseille shocked me: €89 a month, with €35 of that from laundry and drying. Two years later, I'm down to €12 a month—and my clothes last longer. The switch? Cold-water washing, smarter loads, and almost no tumble dryer.
Most modern detergents use enzymes that work best between 15–30 °C. A 30 °C wash handles 90% of daily loads and uses far less energy. I reserve 40 °C for heavily soiled items. Whites get an occasional 60 °C refresh, and that's enough.
I fill the drum to about 80%—enough friction without choking movement. Overfilled loads don't wash well; underfilled ones waste water and electricity. As a visual cue, I can slip my hand between the clothes and the top of the drum.
Air drying saves €15–25 per month depending on usage. I use a rack, airflow, and sometimes a dehumidifier in winter—clothes dry 40% faster with no fiber damage. Fabrics last longer and keep their shape.
I use a microfiber-catching bag for synthetics and wash them less often (3–4 wears for sweaters, for example). Cold water releases fewer microplastics and preserves color.
Conclusion: By combining cold water, the 80% rule, and air drying, I cut €300 a year while keeping clothes spotless. Small habits, repeated, make the biggest difference.

As soon as the temperatures drop, our homes turn into sealed cocoons. The heating comes back on, windows stay shut, and the air starts to feel heavy. Yet a few simple habits can keep it fresh and healthy without losing warmth. The best solutions are natural, low-cost, and work just as well in a flat as in a house.
Every autumn it’s the same story: rain returns, the air cools, and drying laundry becomes tricky. Hanging clothes outside is no longer an option, and using the tumble dryer quickly inflates the electricity bill. Luckily, there are simple ways to keep clothes fresh and dry without wasting energy.
