US Solar Energy Consumption vs US GDP per Capita

US Solar Energy Consumption and US GDP per Capita correlate at r = +0.82 over 43 years (1983–2025), p < 0.0001. With the time trend removed, r = +0.94. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.94). Correlation still isn't causation, but this one isn't an obvious artifact.
