Right, but decades ago coal was the cheapest source of power. We didn't have cheap renewables in the 70s. Solar is cheaper than coal in China.* They could certainly grow (at least) no slower by building huge amounts of renewables rather than coal.

*(I'm not sure if this is on a "spot" basis or annualised to account for intermittency, but then it probably doesn't account for the negative externalities of coal either so let's chalk it up to a draw.)

Bullshit. Not at the scale they need. Solar might be "cheaper" in very confined, specific contexts. But China needs on-demand capacity for a billion people. Renewables + batteries cannot accomplish this.

Plus, solar is cheap partially because you don't need to source that much of it. Try to source that much solar and see what happens to the price.

OK, matched grid prices without subsidy, and cheaper than coal in a fifth of cases.
