Once again, Why is Germany and Europe worried about “winter”?? With the Planet literally on Fire and on the verge of spontaneous combustion on a planetary scale from Man Made Global warming, WHY WORRY ABOUT WINTER???
Per the US Energy Information Administration, in 2019, Germany used 8.6 billion cubic feet of natural gas...per day. That's just one country of Europe.
Per Statista, total EU natural gas consumption in 2020 (which was a low year due to COVID lockdowns) was 379.9 billion cubic meters. When converting to billion cubic feet, this becomes 13,416 BCF in gas consumption in 2020.
So at 100% storage capacity (at least going by your numbers), the EU has slightly over one season's worth of natural gas consumption available in storage...and that's only if their consumption is at 2020 COVID lockdown levels.
Hope they're building more capacity...although from recent reports, it seems firing back up their old coal plants is the path they've chosen.
Perhaps they can burn plastic, tires and feces next winter to keep warm. This should keep their industry spinning like a top too. Worked in Kabul, might work good enough in Western Europe too. All one needs is a positive attitude and gumption.
