I find it interesting that you think is better to have a promise of getting gas (like a Celsius agreement that we will give your money back) rather than having your own gas (your deposits, your gas), which is a bit, interesting I would say.
Not using our own gas in a crisis is one of the many weird things going on at the moment. We also have
half a billion tonnes of coal, and we're mining none of it.
There is no easy long-term solution, unfortunately. I doubt we'll ever be able to be self-sufficient on renewables, given how crowded, small and flat the country is.
Nu.nl summed up some of the measures in Germany: starting next month, public buildings can't be heated above 19
oC, and no heating in hallways. No more lamps on monuments, lights off in shops when they're closed, and possibly a ban on heating private swimming pool. The goal: reduce gas consumption by 2%. My gut feeling tells me it's a drop in a bucket.
It is from these "drops" that the exit path is built. See what the EU is doing now
1. Reducing gas consumption by 15% by the end of the year.
2. This applies to all countries. Do you know what's important here? The fact that only some countries, or rather their industry, is highly dependent (more than 30%) on gas from Russia. It also means that countries that consume 15% or less of Russian gas will also reduce gas consumption.
And that means what? That's right - there will be a surplus of gas of non-Russian origin.
3. Real dependence, or rather a noticeably negative situation in only a few countries. These are countries such as Germany, France, Italy, Hungary. Are you familiar with this list?

The rest of the countries, or rather their rulers, did not sell themselves to the Kremlin ghouls, and did not make their country dependent on the idiotic tricks of the petty under-Fuhrer from the Kremlin. With other countries, in this vile type, the gas terror did not pass, they easily abandoned the "blood gas" and sent terrorist suppliers to hell.
As a result: Therefore, a step-by-step, by 2-3-5% reduction, over time, will allow us to completely abandon supplies from Russia. Unfortunately, to the same Germany it is extremely difficult to immediately refuse gas supplies from Russia - most of their industry is tied precisely to the supply of Russian gas. This is about 40% of all purchased gas. Germany buys 60% from other suppliers.
Europe is Germany and France. Italy is the number 2 debtor after Greece.
Why are the USA and Russia great countries? Because they are not dependent on other countries in all major respects.
If Germany and France want to be large industrial countries in Europe, then they have 2 options: to take cheap raw materials and electricity in Russia or try to become energy independent, and build nuclear power plants, develop the coal industry and other non-environmentally friendly industries.
But in Europe it's not fashionable, they don't want to get dirty and be safe. Therefore, green energy is in fashion there.
And this energy is not enough for production.
A politician should do what the voters want, not what is important for the country. No need to blame the Kremlin for the troubles of Europe.
Europeans are to blame for this themselves.
In Russia, a massive program of gasification of the entire country is now underway in order to increase gas consumption. There are a lot of gas filling stations and there are funding programs for filling gasoline cars with gas.
Thanks for the sanctions.
