There is this idea that we are building wind and solar plants to match the consumption of an average cloudy day with not much wind. If we are able to reach that level of production, we will have an overwhelming excess of essentially free energy on days when when the weather is actually favorable for renewables. As a consequence, on those days we can do energy intensive activities such as produce synthetic fuels or hydrogen, etc. very very cheaply. To me that is pretty exciting.

It is exciting. As long as overbuilding renewables is cheaper than grid scale storage, that will be the outcome. Battery advancements will probably eat away at this quite a lot though. What really will also be amazing is when the cost of renewals plus some storage (like a days worth) crosses below the price of operating a natural gas power plant. At that point the whole grid will go green very quickly. We’re a ways from there, but it’s also probably not as far away as many think.
