Absolutely no reason to worry about supply, cold homes, or lights going out.

This was always scare-mongering. The main consumers were the German petro-chemical industry producing for export and thus undercutting the European competition with cheap Russian gas. These have now largely shut down their old extremely wasteful plants as only the cheap energy supply was keeping them profitable and no amount of LNG would help with that.

In the short term this is of course not great for the German GDP (and company profits), but it forces them to innovate and switch to processes that can use renewable energy, so all in all that is probably a positive development.
