Getting Past 30 to 40% Wind and Solar Costs?

For the next 20 years, 30% wind and solar is basically all we're going to get. And beyond that, it really becomes implausible. Massive grid storage is the kind of thing we should be thinking about as we'll have that in 40 to 50 years. After 30 years, maybe we'll have some game changing grid storage kicking in. That'll be a game changer, but not in the next 20 to 25 years.
