Solar's gone down in price 80% in a decade, and is still continuing that downward trend.

Wind, both on and offshore, is also getting cheaper.

By 2030, new solar will certainly be cheaper in China than it is to operate existing coal plants.

I'm a lot more comfortable betting that mass-manufactured things get cheaper, than I am on the price of natural gas a few years or a decade out. With solar and wind going down another 50% and battery prices under $100/kWh, the economics are pretty powerful.

The politics are just as powerful; China has massive internal pressure to clean up the air (and people have been reminded of how clean it could be), and a chance at replacing the US for world leadership if it can show the way forward on climate.
