US Energy Use per Capita vs US Imports

US Energy Use per Capita and US Imports correlate at r = -0.35 over 55 years (1970–2024), p = 0.0086. With the time trend removed, r = +0.55. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is -0.35, but once each series' time trend is removed it becomes 0.55. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
