1. Coal is past the point of no return
Coal has long had one advantage over other energy sources: it's cheap. But the huge growth in the extraction of shale gas via fracking over the past decade has sent natural gas production soaring and prices tumbling. And advancements in renewable energy technology during that same time span have reduced prices in that industry as well, even allowing utility-scale solar to bring its prices in line with natural gas. Money talks: natural gas overtook coal for a few months in 2016 as the United States' primary source for electricity production.
The EIA's Annual Energy Outlook has coal rebounding for the next few years as record-low natural gas prices start to tick back up, but it predicts that natural gas will become the United States' energy source of choice by the early 2020s. And renewables are pegged to overtake coal before 2030 rolls around.
The market has already made its choice — especially as many utilities have decided to shutter coal-fired power plants — cementing coal's death spiral.
2. Robots are more of a threat than regulation
Even if President Trump magically resurrected the coal industry, that doesn't mean that jobs would come back. Automation is a much more immediate threat than overregulation.
In 2008, the coal industry hit its greatest production ever right around the time that employment numbers bottomed out. That's largely due to a geographic shift in production. Trump has made it a point to highlight the plight of miners across Appalachia, but the industry has undergone a clear and steady shift away from underground mining in that region to surface mining in the West. Surface mining — ripe for automation as it's much less labor-intensive — now encompasses 66% of production compared to 34% for underground mining. Per Brookings, Wyoming's surface mines employ far fewer people than West Virginia but produce four times as much coal. Any coal revival would mean putting autonomous trucks to work in Wyoming — rather than miners in West Virginia.
