What Happens When Facebook Heats Your Home

This is a most excellent place for technology news and articles.
Germany has this concept implemented in a lot of places, too.
Ironically this results in some problems now. For example the city Salzgitter (100k inhabitants) is heated by the local steel plant – which currently transitions towards green steel. Their transition also leads to a shut down of their blast furnaces, leaving the inhabitants of Salzgitter out of heating.
No idea what their plan is to replace it, though.
