Coal is a dead tech. Any government propping is just that, short-term gain and propping up a dying industry. It is happening whether you like it or not. Oil is next and it will go out harder than coal.
A government should not be squandering treasure to hold up dying companies and technology. It should be using that treasure (your tax dollars) to prepare. Things like retraining workers to different industries, infrastructure improvements for towns affected to attract other business, etc. Not doing that means that the government is really only looking out for a few wallets now, not you or your family in the future.
