US Wind Power Generation vs US R&D Expenditure
US Wind Power Generation and US R&D Expenditure correlate at r = +0.95 over 28 years (1996–2023), p < 0.0001. With the time trend removed, r = +0.77. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.77). Correlation still isn't causation, but this one isn't an obvious artifact.
