Europeans voted for electricity that expensive, so not sure what the concern is. The government in Germany which shut down local production and decided to outsource it all did not come out of thin air.
If not Europeans, who elects the officials in EU that determine energy policy? Also, your graph shows a substantial decrease in domestic energy production.
If Germans want cheaper energy their only option is to elect other politicians. It's the same problem in Norway. People vote for politicians who do everything they can to increase the price, and then they whine that inflation is sky high. You get what you vote for in a Democracy.
Indeed, it came out of the Merkel government, which was notoriously Russia-appeasing, and while popular at the time, it's reputation is rapidly rotting under the gaze of recent history where Russia assaults Ukraine attempting to eliminate the very concept of Ukraine as an entity and independent people, and threatens all of Europe.
Serious question: What brings people to write these comments? It's so tiresome. Always the same twaddle. Merkel was not notoriously Russia-appeasing, she was notoriously German industry appeasing. She didn't stop a business consortium of several large European energy companies from building a new pipeline to Russia, but neither did any leader of the other European countries involved, nor would have any other German chancellor at the time.
Merkel shut down cold the entire German nuclear power industry, and did not even allow it to do it by attrition; perfectly good plants were shut down.
This move advanced zero climate change mitigation goals, and strongly advanced Russia's agenda of making Germany dependent on RU energy supply. In fact, switching from nuclear to NatGas significantly undermines climate goals.
Keeping the nuclear baseline load and letting it wane by attrition while allowing a pipeline is one thing. Maximizing Germany's dependence on RU is another.
Merkel's active policy was making Germany dependent on Russian gas to the point where Russia thought that there was no way Germany would ever oppose their annexation of Ukraine.
Merkel is a product of the cold war. For her NATO expansion that includes Ukraine was unthinḱable, and most people who lived through the cold war would agree. She never promoted NATO expansion. She thought that through careful diplomacy both peace and trade could be maintained. The US interfered in that.
More importantly, the EU has imported Russian gas through various land pipelines all the time. Nordstream was supposed to secure against various disputes where Ukraine stole Russian gas:
"Naftogaz admitted that because of harsh winter (lower than minus 30C) some natural gas intended for other European countries was retained and used for domestic needs."
It was really Schroeder who got us into that mess, and gas heating for homes was already very popular in the 1990s in Germany (and none of the home owners really asked or cared where that cheap gas is actually coming from).
Trump was laughed at because it was obvious that he wanted us to buy US gas at a premium instead - not because he was 'concerned' about Germany's dependence on Russian gas (and also - of course - because he's a blithering idiot).
In any case, the discussion is about the Baltics getting more independent from Russia (hooray!), not about Germany :)
On social media it is spun as "the Germans laughed at him", when the person sitting in the middle opposite Trump is the Norwegian Jens Stoltenberg, NATO secretary and usually a willing US tool. It was all of Europe together.
That is just plain wrong. https://www.iea.org/countries/germany/energy-mix
