I love this chart showing ~30% year on year growth of solar deployment. What, in your opinion, would most help to increase that rate? Source: https://en.wikipedia.org/wiki/Growth_of_photovoltaics …pic.twitter.com/aPFtVLlFHO
Lots of bad policies would (over-subsidizing it, for instance). But among helpful actions, I'd love to see vastly better batteries.

I think we're probably one more gigafactory from being crushed by cheap batteries. The learning curve is about 5 years behind PV. But how to get them plugged in where they're needed, other than allowing electricity price to fluctuate rapidly at the meter?

It’s hard to beat rapid exponential growth. You could try invent cheaper PV tech, or allow institutional investors to hold money for longer periods (repeal the ban on perpetuities, basically) so that the future discount rate falls. That’ll free up more short term capital.

Great chart, BTW, sent me down the Wikipedia rabbithole! I wonder how the actual output scales along the chart?
-
It would have to match it pretty closely, because it's a logarithmic scale. Early plants get exponentially washed out, so don't matter. And more recent ones have to be used or there would be no follow-on investment. Recent data suggests solar is easier to price than wind.
