Amid a slew of disappointing quarterly financial results from Powder River Basin coal companies, some groups are raising questions about the commodity’s long-term viability.

The Boulder-based environmental group Clean Energy Action released a report Wednesday that predicts the country has already passed “peak coal” and that production will continue to decline because of rising costs. They include Powder River Basin coal in that prediction, even though it has the lowest production costs in the country.
