Not really US electricity demand is going down in the first place. And the major energy demand is going to come from Africa and Asia. On avg 2-3 billion people in Asia and Africa use less than 5% of electricity per person compared to the US and Europe. When you consider the fact that is almost 5 times the population of US and europe combined.

So the solar revolution is more important for the rest of the world as they will be the major users not the US.
