Are you still gainfully employed or are you retired? I've noticed that people who aren't still working are having a hard time wrapping their minds around what is happening in the energy field. Your figures on capacity factor are reasonable for solar and wind. Let's use 15% as a conservative figure for utility-scale solar in China, so we can eliminate the costs for trackers and just assumed fixed axis racking anywhere in China and not just in the high desert plateaus. Would you accept 95% capacity factor for a coal power plant, letting them run as a baseload plant with a reasonable amount of downtime for refueling and maintenance? (Even though actual data is that the average capacity factor of a coal power plant in China is now 46% on average.) Last year China installed 277 GW of solar, which at a capacity factor of 15% is 41.5 GW of new capacity. If they added 41 GW of coal, which even at a 95% capacity factor, that is only 39 GW of new coal capacity. Now look at what projects they have approved and under construction. That puts coal in perspective. You are sadly misinformed if you think solar will not be the dominant source of energy by far worldwide by 2050.
