Well, I don't live in Russia, but if I'm allowed to suggest.. I don't really think there's a reason to panic in the long run. Russia still has lots of potential in the 'comparative advantage' side of the street. For example, let's take a look what else Russia can export:
As we all know, the foundation of the EU economy is Germany, France, and Italy and Russian electricity is way more economical than in those countries, so make your own conclusion. Also, the infrastructure to deliver electricity seems to me being way cheaper and more reliable than the infrastructure to deliver something like natural gas and oil.
Also, the demand for electricity is constantly growing in the EU. (And, yes, the electric cars could help..)
What do you think of that?
