I am saying it is because of greed, the cost to produce the power did not changed so they increased the prices, is there a risk that the locals will protests and some price caps on profits will be put in place?

Something is super weird with this price increases all over Europe, they don\t make sense, I wish someone will start following where all this profits go and take care of those bastards.

The cost of gas has increased, because it turns out that one of Europe's gas suppliers was a hostile power. Europe is having to buy gas on the open market, which means outbidding the rest of the world for LNG shipments. This is not difficult to understand if you seek out high-information sources.

The profits are going in part to induce LNG tankers to come to Europe. You can ban this, but then the LNG won't come and Europe will freeze. The rest of the profits are going to those companies that had the foresight to invest in non-gas power generation. There is some argument to seize those profits since the current price levels were surely unforeseen, but Europe has rule of law so such a seizure would need to be justified and would be challenged in the courts.

The petrol and diesl prices increased too, causing food prices to increase, also electricity prices increased and the math does not work to blame the gas especially in countries like Romania where there is almost no Russian gas import.

Fuel is fungible, and traded on a global market. Power is fungible and traded on an intra-European market. It doesn't matter whether individual countries were relying on Russian gas; Europe as a whole was.

I understand where you’re coming from but do understand that in about three months time Nordic politicians will be trying to explain why they’re bailing out foreigners for their poor planning at the expense of their countrymen. Not generally a vote getting line of argument.
