US Solar Energy Consumption vs US Forest Area
US Solar Energy Consumption and US Forest Area correlate at r = +0.60 over 34 years (1990–2023), p = 2.0e-4. With the time trend removed, r = -0.64. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.60, but once each series' time trend is removed it becomes -0.64. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
