US Renewable Energy Share vs US College Enrollment
US Renewable Energy Share and US College Enrollment correlate at r = +0.81 over 39 years (1971–2022), p < 0.0001. With the time trend removed, r = -0.61. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.81, but once each series' time trend is removed it becomes -0.61. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
