The interesting point this author makes is that nobody is building a future electricity grid. There is nobody who can make such high-level choices about the mix of energy resources - choosing to allocate such-and-such here, thus-and-so there, to get an optimal blend - in the way that all of us armchair engineers tend to think about the problem.

What is actually happening, according to this author, is that bankers are evaluating specific energy projects, individually, and choosing to fund the ones which look like they will offer the best return on investment. That's it: there is no system. The future grid will consist of whatever happened to get built along the way, and our economy will adapt to the emergent characteristics of that "system".
