Summary

The proliferation of AI agents, projected to exceed 1 billion by 2029 and perform 217 billion daily actions, is transforming IT inefficiencies from mere performance issues into significant financial and environmental liabilities. Global IT spending on data centers is forecast to increase 31.7% to over \$650 billion in three years, largely driven by AI. This surge is expected to double global data center electricity consumption to 945 TWh by 2030, with generative AI queries consuming approximately 10 times more power than standard searches. Additionally, AI-related water demand could reach 4.2 to 6.6 billion cubic meters by 2027 for cooling. To mitigate these impacts, CIOs are advised to revisit business objectives with new metrics like "intelligence per watt," adopt a sovereign AI approach when evaluating hyperscalers, control efficiency at the data layer through optimization, and fine-tune the application layer using techniques like intelligent model routing.

Key takeaway

For CIOs managing AI initiatives and budgets, your focus must extend beyond performance to encompass financial and environmental sustainability. Implement "intelligence per watt" as a key metric to evaluate AI system efficiency and value. Prioritize vendor contracts that offer transparency on variable costs and ensure sovereign AI capabilities to avoid lock-in. Optimize your data layer operations and fine-tune application designs to reduce compute, cost, and carbon footprint.

Key insights

AI's escalating energy and water demands necessitate strategic CIO intervention across the entire AI stack for cost and sustainability.

Principles

• Inefficiencies in AI code incur financial and environmental costs.
• Measure AI value beyond cost per query, e.g., intelligence per watt.
• Control over AI infrastructure and data is crucial for flexibility.

Method

Optimize the AI stack by revisiting business objectives, adopting sovereign AI for hyperscalers, controlling data layer efficiency, and fine-tuning the application layer with techniques like intelligent model routing.

In practice

• Review AI vendor contracts for variable token costs.
• Compare hyperscaler sustainability reports, e.g., water usage.
• Optimize search, retrieval, and vector indexing.
