US Coal Consumption vs US Solar Energy Consumption
US Coal Consumption and US Solar Energy Consumption correlate at r = -0.85 over 43 years (1983–2025), p < 0.0001. With the time trend removed, r = -0.76. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = -0.76). Correlation still isn't causation, but this one isn't an obvious artifact.
