US Natural Gas Consumption vs US Internet Usage

US Natural Gas Consumption and US Internet Usage correlate at r = +0.79 over 35 years (1990–2024), p < 0.0001. With the time trend removed, r = -0.74. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is 0.79, but once each series' time trend is removed it becomes -0.74. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
