That's relevant how exactly?

Low natural gas consumption of Europeans is relevant to a thread about Europeans consuming too much natural gas. I don't know how else to explain it.

The issue here is Europe needs natural gas for the foreseeable future...

As everyone does. The real issue is that unlike most regions, Europe doesn't have any natural ressources in the energy department. That's hardly a lack of foresight or planning as OP suggested, it's just a shitty reality we find outselves in.

...and has been content to rely on Russia.

As opposed to Saudi or Iranian oil or American LNG which would be twice as expensive. You're making it look like we're full of great options. I don't see them.

The dependency on Russia is the problem.

Agreed. That's why we're moving towards renewables faster than any other major and developed region on the planet on a per capita, per GDP and % of energy production basis. It just won't happen over night. Sorry, I guess.

And speaking of our dependency on Russia, let's look at how big it really is.

Energy production in the EU by source

Russia in the European energy sector

According to Eurostat, 30% of the EU's petroleum oil imports and 39% of total gas imports came from Russia in 2017.

So according to the graph in link number one, 36.3% of our energy production comes from petroleum of which 30% is Russian and 22.3% comes from gas of which 39% is Russian. So...

30% of 36.3% + 39% of 22.3% = 0.3 * 0.363 + 0.39 * 0.223 = 0.19587 = ~19.

So, roughly 20% of Europe's energy comes from Russia. As the great saying goes, not great, not terrible.
