US Electricity Generation vs US Forest Area
US Electricity Generation and US Forest Area correlate at r = +0.85 over 34 years (1990–2023), p < 0.0001. With the time trend removed, r = -0.11. 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 -0.11 — the relationship is probably coincidental, not causal.
