'Coal is on the way out': study finds fossil fuel now pricier than solar or wind

Around 75% of coal production is more expensive than renewables, with industry out-competed on cost by 2025

Around three-quarters of US coal production is now more expensive than solar and wind energy in providing electricity to American households, according to a new study.

"Even without major policy shift we will continue to see coal retire pretty rapidly," said Mike O'Boyle, the co-author of the report for Energy Innovation, a renewables analysis firm. "Our analysis shows that we can move a lot faster to replace coal with wind and solar. The fact that so much coal could be retired right now shows we are off the pace."
