In 2016 "coal’s share of power generation in the state fell to about 58 percent, from 86 percent in 2006," reports Bloomberg. John Bartlett, who helps manage about $2.5 billion of energy and utility stocks at W.H. Reaves & Co. Inc. in Jersey City, "estimates that by 2021, gas-fired stations in Ohio will be able to produce 20.4 gigawatts—almost double their current capacity—while coal will hold steady at 15.4 gigawatts."

"Historically, gas prices have been volatile," Bloomberg reports. "The risk is that by the time they swing up again, other producers—nuclear, as well as coal—could have been driven out of business."
