Good news for environmental fans! The economics of renewable power generation are more attractive than those for burning coal even without considering externalities – the cost of pollution and CO2. In 2017, Coal was used for 29% of energy production, so lots of room to build out renewables.
Expect utilities to struggle with assets of that burn coal as they become less competitive.
