What is clear is that the EU cannot magically stop consuming all the oil and gas it used to buy from Russia. It can gradually reduce it as it installs more renewables, as it has been doing for years.
I think there is a lot of window-dressing going on here, and I would like to see how they approach energy policy in the medium term, not to mention the long term, as politicians are not usually capable of thinking beyond one term of office. For me the lesser evil is to install more nuclear power plants, because fossil fuels mean putting the EU in the hands of other countries, many of them dictatorships. And to make a fool of themselves as in this case.
They could have, and still could in the future, but they are denying that for some reason. There are laws in place, and aims and roads to take, but renewable energy is the way to go for this and they just do not spend that kind of money on it.
From all kinds of food to all the energy needs, every nation has enough power to do it all by themselves and they only need to spend some money on it now, if they spend it now, they will be great in the future. Like have solar panels EVERYWHERE that gets sunshine enough, that would require tens of billions of dollars worth of investment, and yet you will not need Russia afterwards, and for some reason they still do not do it enough.
