Nothing wrong with solar, hence the results. The drawback is in storing and transporting that energy, we can't do that efficiently yet. Once that hurdle is gone, that graph will be rocket ship :-) We can't make a battery that lasts 5 years. Coal is old but that's what we do well, so until the new king comes in we still be doing silly things we do. Solar, wind, hydro and nukes are the future of the energy work and it should be distributed, except "nukelar" :-) That's my personal opinion.
For storing energy, one of the best solutions IMHO is pumped-storage hydroelectricity.

It's a great solution if you happen to have the right geography for it. Not everyone does. And many countries have built out most of the suitable hydro sites already.

Agree 100% check this baby out :-) https://www.verbund.com/en-at/about-verbund/visitors-centres/kaprun This should be a template. Every lake or river can do something similar (at scale) In Kaprun they used nature to help them out, it's brilliant.

I'm a big fan of nuclear as well. But the nice thing about solar is how it perfectly correlates with human electricity usage (ACs suck a lot of energy compared to all things light, computing, rotation motors)

Yes, solar is great for certain loads. Unfortunately there isn't infinite demand for those loads. So as the % of solar goes up, the cost to supply the remaining needs with solar goes up too.
