So far I’ve mostly changed how I do stuff, rather than what i do. Electric car instead of ICE, Bike and train for commuting, Solarpanels and 20kWh batteries for most of my summer time energy needs.

At work I have more possibility to make a difference, though. So far I’ve had batteries introduced (solar was already norm) as an accessory to “our” buildings, I’ve gotten 2 thermal batteries (sand) built and are currently investigating building mounted small scale wind power. Among other things.

As bad as airing out a hot car is, it takes on a different need when its -20C and you need to thaw the car out before going to work in the morning. Much preferable to do that from inside.
