US Wind Power Generation vs US Military Expenditure
US Wind Power Generation and US Military Expenditure correlate at r = -0.47 over 42 years (1983–2024), p = 0.0019. With the time trend removed, r = +0.40. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.47, but once each series' time trend is removed it becomes 0.40. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
