at the end of the day its government that honestly should incentivizes the use of renewable energies.
Coal is a very specific resource. And the roots of "preference" are historical. I recommend reading the history of Britain, and the very difficult decisions associated with mine closures. The fact is that coal mining by the 20th century used huge numbers of workers. In many countries and in many mines, mining is done purely by hand, and that means thousands and thousands of people, and even entire small towns. Plus - the cost of coal and the cost of its purchase or subsidy programs - a very tidbit for those who trade in coal. That's why some countries continue to exploit cheap labor, making money on it, while closing the mines will not only deprive miners of income, but also create very significant social tensions. Social tensions in the mining regions, for example, are the main reason why developed countries subsidize and support the coal industry. Just imagine what would happen if 100.000 miners who do not know anything but coal mining and the saddest thing is that they do not want to change anything in their lives.
