That's about the size of it. What I don't understand (well, I do because it's not about having a balanced power plan it's about control) is why not use wind turbines, solar, nuclear, and natgas with one another, aka this balanced ~~breakfast~~ power generation plan? Renewable devices have their uses, but not at the scale we need to provide for. ea Coal, while it is the best source of thermal energy we can get in a "easy to use, doesn't explode when handled" transportable form, is never going to be a clean method of power generation. We should have looked to nuclear decades ago.
