US Solar Energy Consumption vs US Resident Patent Applications
US Solar Energy Consumption and US Resident Patent Applications correlate at r = +0.56 over 39 years (1983–2021), p = 2.2e-4. With the time trend removed, r = -0.63. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.56, but once each series' time trend is removed it becomes -0.63. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
