US Renewable Energy Share vs US Population
US Renewable Energy Share and US Population correlate at r = +0.87 over 61 years (1965–2025), p < 0.0001. With the time trend removed, r = -0.16. 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 -0.16 — the relationship is probably coincidental, not causal.
