It seems very unlikely that with sustained temperatures of -5 to -8°C in the winter months, which seem to get longer again, heating can be achieved with renewables in any way.
Heat pumps were already collapsing and making irritating fan noises at -8° this winter. Converting to heat pumps is expensive and the service costs are expensive, too.
LNG is needed for fertilizer and other chemical products, too and is hard to replace at all.
By all means, try renewables, but these enthusiasm waves leave me skeptical.
