Irreversible? where is the coal going? Since 1882 we have used coal-fired power stations for energy i would have hoped it had some sort of competitive edge against what is coming and yet they have always been subsidised....the below figures being only for G20
"Our study actually found $64 billion dollars of support per year being provided to coal, both the production of coal and its consumption. We also found — which was especially alarming — that subsidies to coal-fired power have increased if you compare them with data we found in 2013-14. So within a three-year period, they've gone up from $17 billion dollars per year up to almost triple, at $47 billion dollars per year."
