US Solar Energy Consumption vs US Internet Users

US Solar Energy Consumption and US Internet Users correlate at r = +0.58 over 35 years (1990–2024), p = 2.8e-4. With the time trend removed, r = -0.61. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is 0.58, but once each series' time trend is removed it becomes -0.61. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
