US Electricity Generation vs US Cereal Yield
US Electricity Generation and US Cereal Yield correlate at r = +0.83 over 40 years (1985–2024), p < 0.0001. With the time trend removed, r = -0.23. Likely spurious (shared time trend).
Verdict: Likely spurious (shared time trend). Both series mostly just trend over time. After removing that trend the correlation collapses to -0.23 — the relationship is probably coincidental, not causal.
