But what about the costs of energy storage to provide baseload capacity? And on top of that, if the goal is CO2 reduction, we need to generate 4x more electrical energy to replace fossil fuel chemical reagents and things like fertilizer production with non-fossil fuel sources that are far less 'efficient'. And that is before we start talking about future growth of electrical needs.
It won't be cheap, but neither will be the effects of global warming. The important question is whether it can be done or not, and on that front all signs point to yes.
Regarding storage, there is a tradeoff between an improved grid and storage requirements. It's always windy somewhere, if you have the grid to transport that power to where it's needed, you need much less storage.
