I replace my bulbs with LEDs or compact fluorescents

Thermostatic valves

I install thermostatic valves on my radiators and set them to max. 3.


I install thick shutters or curtains in heated rooms and close them at night or when I leave my home.


I have my mobile phone repaired rather than discarded.

Picnic basket

I don't use disposable dishes when I eat outdoors.

Open windows

I turn off the heating when I ventilate the rooms/rooms.

Be careful to open the windows wide for 5 minutes instead of tilt and turn window all day long!

Christmas tree

I make my own Christmas decorations (origami, cotton, cut-outs) rather than buy them and I choose LED Christmas lights.


I replace one portion of red meat with one portion of white meat per week.


I avoid using the microwave to thaw food.

Fruit and vegetable basket

I buy fruits and vegetables in bulk and without packaging.


I avoid air conditioning as much as possible (if I am too hot I hang a damp sheet on my window to cool the room. If that's not enough, then I prefer the fan.)

Shower head

I replace my shower head with a water-saving head / I install a flow limiter on my faucets.


I make my own fries and prepare my own homemade mayonnaise.


I regularly defrost my freezer (every 6 months).


To travel on a city trip, I prefer the train if possible. If I fly, I compensate my flights.
