US Solar Energy Consumption vs US CO₂ Emissions per Capita

US Solar Energy Consumption and US CO₂ Emissions per Capita correlate at r = -0.80 over 42 years (1983–2024), p < 0.0001. With the time trend removed, r = -0.57. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = -0.57). Correlation still isn't causation, but this one isn't an obvious artifact.
