US Solar Energy Consumption vs US College Enrollment
US Solar Energy Consumption and US College Enrollment correlate at r = +0.51 over 27 years (1983–2022), p = 0.0062. With the time trend removed, r = -0.65. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.51, but once each series' time trend is removed it becomes -0.65. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
