US Energy Use per Capita vs US Internet Users

US Energy Use per Capita and US Internet Users correlate at r = -0.70 over 35 years (1990–2024), p < 0.0001. With the time trend removed, r = +0.75. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is -0.70, but once each series' time trend is removed it becomes 0.75. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
