Here's where they said what I summarized as "Europe not buying fossil fuels from Russia is a catastrophe for Europe":

Now, with the exclusion of Gazprombank, the bank handling most of the international transactions for Gazprom (the largest gas producing company in Russia) from the SWIFT inter-bank messaging system, and Ukraine unwilling to renew transit permits through its territories, the cheapest form of natural gas supplies to Europe will likely dwindle to a mere trickle. That will leave Europe with expensive LNG from Qatar and the US, as well as some pipeline gas from Norway and through Turkiye, which is Russian gas in a roundabout, third-party way. As always: higher complexity comes at a higher price — a direct consequence of the EU’s economic war on its largest energy supplier.

Will this lead to a repeat of the 2022 price rally then? Hardly. As one can see from the extent of layoffs cited above, Europe is deindustrializing fast. Half of the continent’s steel, glass and aluminum capacity, together with fertilizer and chemical plants have already left in the first wave (in late 2022 and early 2023). Now, it’s time for the automotive and machine manufacturing sector to go, together with the “renewables” and battery businesses. Well, energy is (still) the economy, it seems. As industrial demand recedes, however, so does consumer demand. With mass layoffs, and in response to a huge drop in the purchasing power of their money, people started to buy less and less products made with expensive energy, and turned down the heating in their homes even further.

Here's what they said that I summarized as "they must reverse course as soon as possible and stop trying to depend on renewable energy":

In light of the above it’s even harder to understand how European elites could be so irresponsible. Instead of revising their energy / foreign policy, they have doubled down on “renewables” even as they severed all vital links to their primary source of cheap fossil fuels. Contrary to its vital economic interests, Europe has tied its import dependent economy to a fast sinking “rules based world order”, together with LNG supplies from the U.S. with diminishing reserves and a soon to be peaking production. Instead of doing everything to prevent a war with their biggest neighbor, and to find a cooperative coping mechanism to deal with the coming long decline in world energy production, the EU and NATO remained hell bent on expansion and sabotaged every deal along the way — together with the many opportunities for peace. Even as the war is being lost as we speak, there are still no talks about building a lasting peace taking both side’s security considerations into account. Instead, we hear more ‘peace through strength’, ‘deterrence’ and sending European troops into Ukraine to freeze the conflict… Only to prepare the country for a renewed offensive few years later. Just like many times before in the old continent’s battered history confrontation was chosen over cooperation, ultimately leaving Europe in ruins and in a deep economic turmoil. Only this time, in the absence of a cheap and abundant new energy source, the downturn could all too easily become permanent.

That also covers some of "since it doesn't work," as well does what I already included and satirized at some length, the accusation that connecting solar panels to your grid will destroy equipment because when a cloud goes across the sun, the whole equipment suffers some kind of catastrophe.

I'm comfortable with my summary, in other words. The whole thing is so long-winded that it's hard to boil down to simple statements, but it's actually uncommonly direct in what it's saying for this type of propaganda.
