China produces about 80% of all solar panels in the world. Coindicentally or not, it is also the #1 country by coal production; it has the largest number of coal plants of any country (in absolute terms), and the government has recently been ramping up the rate of new coal plant construction after a few years of trying to keep it more or less in check. Most of electricity in China comes from coal (>60%, compared to US’s <20%).
