Provenance Record

Well-structured News article with a clear milestone lead, quantitative depth in the 'What We Know' section, appropriate epistemic humility in 'What We Don't Know', and a grounded analytical conclusion. The 755-word count sits well within the News category range. Internal cross-link to the prior US-only milestone is editorially useful and clearly marked.

All four snapshots successfully fetched (source-0 through source-3, all HTTP 200). Source-0 (Electrek, source-0.html.gz): confirmed 531 TWh wind+solar vs 477 TWh gas in April 2026, 22% vs 20% share, 13% YoY growth, all country breakdowns (China +14%, EU +13%, UK +35%, US +8%, Australia +17%, Chile +24%, Brazil +4%), Kostantsa Rangelova quote verbatim, April seasonality caveat, and no coal-switching finding. Source-1 (Carbon Brief 'clean energy pushes fossil fuel power into reverse', source-1.html.gz): confirmed fossil fuel generation fell 0.2% in 2025, coal dropped 63 TWh to 10,476 TWh, solar grew 636 TWh (33% above prior record), the 1919 coal/renewables parity reference, and wind+solar meeting 99% of demand growth. Source-2 (Carbon Brief 'wind and solar saved UK from gas imports worth £1.7bn', source-2.html.gz): confirmed UK avoided £1.7bn in gas imports, 34 LNG tankers, 41 TWh avoided gas consumption, and gas generation in UK fell to record lows in March and April 2026. Source-3 (CleanTechnica/IEA 'age of electricity', source-3.html.gz): confirmed battery storage as fastest-growing power sector technology, approximately 110 GW new capacity, and costs dropping 45% in 2025. All claims in the article map to their cited sources without misattribution.

Every quantitative claim traces directly to a cited source snapshot. No hallucinated quotes or fabricated specifics detected. The Kostantsa Rangelova quote is reproduced verbatim from the Electrek snapshot. The distinction between the April 2026 monthly milestone and the as-yet-unreached annual crossover is correctly stated and sourced.

Clean submission. All automated checks passed, all four source snapshots verified, no fabrications or misattributions found. The article responsibly contextualizes the April seasonality and the LNG supply disruption as contributing factors. Ready to publish as-is.
