The voluntary reduction of gas consumption by EU countries may help to alleviate the current gas shortage to some extent, but it is unlikely to completely solve the problem.
the reduction of gas consumption may have some negative economic impacts, particularly for industries that rely heavily on gas. It may also be difficult to sustain the reduction over the long term, as energy demands are likely to increase as time goes by.
You don't quite understand what's going on
1. Thanks to the warm winter, the EU countries have significantly reduced consumption and saved both gas reserves and money.
2. But by the winter of 2022/2023, the EU countries, or rather the largest, and countries that are highly dependent on Russian gas (primarily Germany, Italy, France) - found alternative suppliers, signed LONG-TERM contracts with adequate suppliers, and by the beginning of the winter season completely filled the gas storage facilities with the required volume of gas for a standard winter!
And this means that not next year, nor in a year - this problem will not happen again. How will the receipt of money for gas to the country by a terrorist not be repeated
