I wish the author had spelled out the subtextual implications for peak oil demand and the energy costs of solar. I will try to give my perspective I suppose.

We always thought that once solar achieved cost Parity with gas generation, it would be a cascade effect of rapid solarization due to the cost basis alone, finally shedding the necessity of ethical ideology to promote it.

That happened roughly in 2015 for the US, and nothing substantial changed. Then the costs of solar got cut in half. And now as we breach the mythical $1/watt barrier for utility scale solar installation, we still find ourselves breaking oil production records year after year.

We're so far past the "kerosene moment" and barely seeing exponential growth on solar capacity install. Meanwhile China is adding more than 4x as much.

I think the moral of the kerosene story and solar is that it's hard to flip a paradigm that is currently enabling people to get rich. The only time it seems to change is when a law is passed.
