Due to war of Russia-Ukraine, there is shortage of gas supply and foods. After this, european countries agreed to reduce gas demand by 15% in end of this winter 2022.
The close connectivity between Russia and Europe economy cannot be disconnected even in a decade. Europe hyper-depends on Russia for oil and gas and Russia also depends on Europe for funds. Russia started preparing for this invasion long time ago and they know that Europe would be helpless for some years without them. The Russian economy has been fortified to withstand sanctions that's why Kremlin is not soft-paddling its invasion quests. Reducing gas demand would be a big challenge because the economic strength of the members of the European union are not the same. France, Germany or Spain can easily afford alternative source of power but what about less wealthy EU nations. Diversifying their energy source would be difficult because most of them cannot afford it. Hence, these nations would still have to depend on Russian less expensive oil and gas.The goal of reducing gas demand would be possible if richer EU nations would support others that are less prosperous to acquire alternative source of power.
No matter how Russian propaganda tries to impose on the world the idea that the countries of Europe cannot do without Russian oil and gas, and sanctions do not harm the Russian economy, everything goes on as usual. European countries have embarked on a phase-out of oil and gas from Russia, and sanctions continue to intensify and drive Russia into a complete collapse. Europe by the end of the year refuses Russian crude oil, and next year and from oil products. With gas, it is a little more difficult, but even this dependence of Europe will be ended in a few years, not a decade. But for Russia, this will be a global problem, if not a catastrophe.
