Some key insights from the article:

Basically, what they did was to look at how much batteries would be needed in a given area to provide constant power supply at least 97% of the time, and the calculate the costs of that solar+battery setup compared to coal and nuclear.

Look at the other line on the graph. Solar alone, covering up to 60% of energy use, is already cheaper than gas in Las Vegas. Sure, other places will have their own lower numbers, but until we achieve this threshold, we’re just a bunch of reactionaries captured by current business owners. If anyone actually believed in the free market, we’d expect it to trend to that line

I work in this field. I'm trying to change these numbers! We are heading the right direction is the good news. China may well save us all with cheaper panels and battery manufacturing. And if 97% reduces our emissions even 50% on todays emissions then we can start talking about actually meeting some climate targets.

So this is all good news, but as I also said: I work in this field and know we have a long way to go yet. There also isn't a single answer. Batteries, smart grids, grid-interconnects, efficiencies, supply mixes, demand offsetting; power is the best thing in the world to work in right now, it touches sooo many aspects of humanity and is changing so fast!
