At current usage and export levels, the existing stockpile will not even drop below 45%.

That is assuming continuous imports. Do you not know what percentage of energy usage the stockpile would cover?

Prices have in fact begun to come down in September after rising in August, and this is true of retail cost

Is it?

Again, no. You're bringing up irrelevancies that have nothing to do with my simple, singular point. If you would like to know my point, refer to thread title.

'Make it through the winter' could mean literally anything. As long as Germany doesn't collapse into Trizonia or something, then you'll say: hey, its GDP declined by 10%, unemployment is at 15%, but the state still exists.

Russia is not Germany's primary supplier or energy, or actually any kind of supplier at all. Germany stopped oil imports from Russia by April. and stopped reduced natural gas in late August. The chart shows that Germany has simply replaced russian imports with other sources. Source
