US Electricity Generation vs US Median Age

US Electricity Generation and US Median Age correlate at r = +0.95 over 39 years (1985–2023), p < 0.0001. With the time trend removed, r = +0.92. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.92). Correlation still isn't causation, but this one isn't an obvious artifact.
