Yes. Sadly, Poland doesn't have much room to maneuver at the moment. Putting aside the coal miner unions and the economic collapse of coal mining regions it would cause if Poland had the option to quickly move off, cleaner sources remain either prohibitively expensive and/or blocked by environmental groups (you're as likely to find environmental groups protesting nuclear as shale gas). Add to that the dependence on Russian gas (save for some Norwegian gas), the low cost of coal and Germany's smarmy deals with Russia including Nordstream that are designed to cut central Europe out with serious political consequences, Poland really is in no position to choose otherwise right now.
