US Coal Consumption vs US Electricity Generation
US Coal Consumption and US Electricity Generation correlate at r = -0.34 over 41 years (1985–2025), p = 0.031. With the time trend removed, r = +0.82. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.34, but once each series' time trend is removed it becomes 0.82. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
