US coal production

As US coal production has declined, cycling fatalities have increased, a correlation that reads like a misguided environmental trade-off: fewer miners, more cyclists, and no safety improvement for either. The coefficient is -0.852 across twenty-one years, during which coal's slow death and cycling's dangerous growth traced mirror images of each other on a chart that no energy policy analyst would have predicted or endorsed.

US coal production declined from about 1.1 billion tons in 2002 to about 540 million by 2022, as natural gas and renewables displaced coal in electricity generation. Cycling fatalities grew from about 660 to over 1,000 during the same period. Both trends are products of the same energy and transportation transition: coal declined as cleaner alternatives became cheaper, while cycling grew as urban transportation alternatives became more popular. The shared variable is the modernization of the American economy—away from fossil fuel extraction and toward urban, service-oriented lifestyles that include cycling commuting. The mine closes, the bike lane opens, and neither transition was managed as safely as it should have been.

Twenty-one years of coal declining and cycling deaths rising is a portrait of an economy in transition: the old energy source fades while the new transportation mode grows, and both transitions involve more risk than the policy response has addressed. The coal mine and the bike lane are different symbols of the same evolving economy. The miner retires, the cyclist commutes, and neither was given adequate protection.
