US Egg Consumption per Person vs US Electricity Generation

US Egg Consumption per Person and US Electricity Generation correlate at r = +0.52 over 39 years (1985–2023), p = 6.9e-4. With the time trend removed, r = -0.45. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is 0.52, but once each series' time trend is removed it becomes -0.45. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
