The problem of relying on Russia for energy was obvious. There isn't a singular "the solution" because there were many possible solutions, nuclear energy being just one. In addition to investing in wind/solar, there are other solutions besides nuclear. Particularly, fracing and coal mining. Both of these are unpopular for obvious reasons (which is the reason everybody talks about nuclear instead), but I think both are better than the political autonomy of an entire subcontinent being threatened by a belligerent foe.
