Note that solar (other than solar thermal) and wind do not include cost of energy storage. Gas combined cycle (basically, a jet engine + a steam turbine heated by the jet exhaust) does beat coal in many of these estimates, but this is new technology that has only been deployed widely by first world countries. Generally, only countries with developed aerospace industries have that infrastructure to built thermally efficient gas turbines. Thermally efficient gas turbines need advanced materials and fabrication techniques like monocrystal casting. These figures are highly dependent on the kind of infrastructure available to a country. What's cheap for a country like the US with extensive gas turbine manufacturing is not going to be cheap for other countries. There's a reason why so many developing countries use coal: it's a much more low tech solution that does not require complex industry. If your claim about the lower cost of gas was limited in scope to the US and similarly developed countries, I'd agree, but I was talking in global terms. Many countries are sticking to coal because it's cheaper: https://www.economist.com/briefing/2018/08/02/india-shows-how-hard-it-is-to-move-beyond-fossil-fuels https://www.economist.com/briefing/2018/08/02/india-shows-ho... https://www.economist.com/leaders/2019/08/22/asian-governments-are-the-biggest-backers-of-the-filthiest-fuel https://www.economist.com/leaders/2019/08/22/asian-governmen... https://www.spglobal.com/platts/en/market-insights/latest-news/natural-gas/100419-analysis-next-wave-of-asias-lng-demand-hinges-on-affordability-competing-fuels https://www.spglobal.com/platts/en/market-insights/latest-ne... There are good reasons to move off of coal, regardless. Coal extraction is dirty, and it generates pollutants that are much worse than gas turbines. It'd probably be good policy to facilitate the export of gas turbines to developing countries.
