I finally had the time to write a post in this interesting thread.
We have gas heating for warm water and heat in an apartment we rent, 5 room, 120 m².
We use electricity for cooking and one washing machine, no dryer. Two electric bikes we use all the time.
I did install a small 60W solar panel with a DC circuit and various adapter to various voltages. We charge our laptops, smartphones and usb battery packs from the solar balcon.
Before 2020, we had 3 days a week with an empty house. Since Covid, I do mostly home office and there is always somebody at home.
our energy consumption was:
2019: 1950 kWh (family of 4)
2020: 2200 kWh (family of 4)
2021: 2600 kWh (third kid was born, parenthood leave)
So covid, home office and the constant presence at home added roughly 700 kWh to our consumption. We traveled a lot less but we do spend one month a year back to our parents in Ticino, so we only are 11 month in this apartment.
In general though for our family and apartment size I think we are doing ok.
