Yep. Coal is expensive. Mining, long distance transportation, plant clean up and disposal of toxic waste. Natural gas is just a pipeline for transportation, no plant cleanup or toxic waste disposal, and per btu it’s cheaper than coal. Wyoming is stuck on coal because it’s the primary industry. Natural gas is abundant and cheap. There is no reason for coal when other options are both cleaner and cheaper. NG plants can also be ramped up immediately based on need and coal plants require 24 hours to bring up to operation.
