The first two links in the post are somewhat hyperbolic but the following posts are pretty good. The initial articles put it in terms of destroying the utility grid. I don’t buy that. But it is true that the Utility Grid will change a lot over the next two decades. The group of links that the above hyperlink takes you to are a good introduction as long as you don’t get worked up about things being destroyed, that is just a line to get you excited.
