coal mill energy consumption :

Short-Term Energy Outlook - U.S. Energy Information ...

2021-11-9  Coal. We expect coal consumption in the electric power sector to rise by 80 million short tons (MMst), or 18%, in 2021. The increase in the electric power sector’s use of coal reflects higher natural gas prices this year compared with last year. However, electricity generation from coal-fired power plants has not increased as much in response ...
