Re: Good on them
Replacing electric heaters with gas ones is not bad if your electricity source(s) are predominantly fossil fuel, as even a typical large-scale generator (without heat reuse in a cogeneration manner) is only 40%-ish efficient and then you lose another couple of percent in the distribution network, whereas a gas *heater* (or boiler) is typically 80%+ efficient. Of course if the majority of your electricity is from renewable/nuclear it is a different story.
I seem to remember some news about Germany shutting down nuclear plants to be "Green" and then importing electric from neighbours generate largely from Russian gas...or am I misremembering?
