## Recent evidence

- [confirms] Microsoft Says United Kingdom Grid Connections Take Eight Years, Choking AI Data-Center Buildout (2026-07-28): Microsoft says UK grid connections take eight years, leaving Britain ~2GW of data-center capacity (a third of America's per capita) and hoping for 6GW by 2030 while the US targets 90+, per the article. Interconnection timelines, not chips or capital, are shown setting the pace and geography of the buildout.
