Not if you look at how it is becoming more common to use in Europe, as renewables are increasingly adopted. In the UK, with around 20% of capacity possible from nuclear, 20% from wind, gas is the largest source that makes up any shortfall from renewables and nuclear. Coal is generator of last resort kicking in after using the international interconnects. Both of those non-traditional uses are down to simple economics - it's not economic to use coal unless there is literally nothing else available. It's reached a point where the couple of remaining UK coal plants are paid a small subsidy to stay idling, ready for spin up rather than cold start, for days or weeks on end without actually providing power to the grid. Coal will be entirely gone before 2025. Gas is getting to that point, but for now, it's the bulk of UK generation. Peaking is mostly Dinorwig and the other pumped storage scattered around the UK, along with the secondary ability to disconnect the highest industrial users - around 10% of supply I think - they get a discount on rate for accepting an interruptible supply to help manage the grid.
