Russia is deeply hostile to Eastern Europe and, in fact, the entire Europe. That has always been the case. You're sitting in faraway Venezuela and your country is seen by Russia as something to use to annoy the USA with so your relationship with Russia is naturally not hostile. From an EE perspective, Russia is going to have to be stopped by any means necessary be it militarily or economically. The EU sanctions against Russia are the only way.

And no, Russia is not going to be able to export too much in the way of gas to India. Due to the existing pipe infrastructure, Russia's biggest gas buyer will be Europe for quite some time. It takes time and a lot of capital to build the pipelines to export gas to other customers like China.

I agree with you that relying on Russia for anything important like energy is foolish. Russia does not think in terms of mutual economic benefits. It does not play positive sum games. Russia is the only major European country that hasn't given up for old school imperialism and colonialism.

Europe finds itself in this mess mainly because of German short-sightedness, greed and stupidity. Nuclear power is the best form baseload power there is. France has made the right choice. Renewables have a minor role to play that could grow depending on technological development. Coal is horrible but coal fired power plants could help with the power shortages.

Europe should go nuclear in a big way and stop dealing with Russia. Fossil fuel use is going to ruin the planet anyway. The business as usual scenario would've ended in a really shitty way. So, maybe this war is has the unintended positive consequence of helping Europe get rid of fossil fuels.
