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.
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.

California's solar is leading to a negative price reasonably often. And it doesn't work at night without large-scale batteries. The Gigafactory is producing tens of GWh of batteries (annualized), which is a rounding error on the scale of the world electricity grid.
