2020
installed smaller water heater (65L vs 200L) which needs much less energy
new cordless hoover
2021
changed electric tarif to 100% renewable
replaced gas oven with electric oven
replaced gas hob with induction hob, but retained 2 ring gas hob for certain pans that are occasionally used. Gone from 4 bottles per year to less than 1. Further, electric cooking uses significantly less energy
installed another 700W of solar PV taking us to 1780W. This provides our daytime usage 100% even on cloudy days, and the surplus is fed into the hot water tank; In 2021 we spent less than 1€ on domestic hot water
Installed a heat pump to heat the house in spring/autumn running off PV, and reducing our dependance on wood for heating.
Extended the house and used nearly 3 times the legal minimum insulation.
The garage extension was built with the smallest possible foundations/concrete and wood used for the walls.
