The cheapest coal in America has never been so expensive, as demand for the dirtiest fossil fuel surges ahead of winter.
Coal from the Powder River Basin in Wyoming and Montana more than doubled in the past month to $30.70 a ton, according to data from S&P Global Market Intelligence released Monday. That’s the highest in spot-market records going back to 2005. Pricier coal from Central Appalacia has also surged to a 12-year high.
