Fernwärme isn't gas for heating. Fernwärme in .de uses a variety of fuels, including gas. AFAIK none of the operators rely on a single furnace. Gas for heating is mostly furnaces in people's basements or bathrooms. Moving to electricity would require replacing a total of about thirteen million pieces of hardware. More if you count small and cheap things like gas stoves that can be replaced in hours of work rather than days. It's like a car in some ways: Once you've bought a diesel car, you don't have a choice of fuel any more. You've chosen.
