Coal dominates Indiana’s energy production, but the industry has faced major challenges nationwide over the past decade. But a new study asks what would happen if coal workers were retrained to produce a different type of energy—solar.
The research estimates the cost to retrain current coal workers for related jobs in the solar industry. Joshua Pearce, a Michigan Technological University engineering professor and the study’s coauthor, noted the increasing number of major coal companies filing bankruptcy.
“There’s, I think, a large concern in the public to be able to find, you know, hard working people good jobs,” said Pearce.
The study measured the “best case” and “worst case” cost range of retraining Indiana coal miners, anywhere from $8 million to $82 million. It estimates a rage using scenarios in which different numbers of coal employees choose to work in the solar industry.
Nationally, worker retraining costs range from $180 million to $1.9 billion. Pearce said those figures aren’t actually that high.
“A single company, and the CEO pay for a single year, could more than cover the training for all of his employees,” he said.
The high end of that range is about 5 percent of the coal industry’s roughly $40 billion dollar annual revenues.
Pearce also said solar is a far cleaner energy source than coal and is competitive economically.
“If we want to maintain low electrical prices in the United States, particularly if we’re interested in conserving the environment,” Pearce said, “it makes a lot of sense to make the transition as soon as possible.”
Indiana’s coal industry employs roughly 4,000 people, while only 1,600 Hoosiers are employed by the solar industry. But that trend flips nationally, with 150,000 people employed by coal compared to 210,000 who work in solar.
The study was published in the journal Energy Economics by Pearce and his coauthor, Oregon State University public policy professor Edward Louie.
