UK publishes sustainable AI rules for government employees

The UK government released draft "Use AI Sustainably" guidelines telling civil servants to skip AI when a spreadsheet suffices and to pick the smallest model with short prompts when AI is needed. Critics note smaller models hallucinate more, and prioritizing sustainability over productivity may slow AI adoption.

• Guidelines urge skipping AI if a spreadsheet can do the job
• When AI is required, staff should use the smallest model and few prompts
• Smaller models hallucinate more, hurting output quality
• US data center additions may hit ~38 GW in 2027 versus ~10 GW in 2025
