Energy and AI Summary

Core Content

This document explores the intersection between artificial intelligence (AI) and the global energy sector, highlighting the mutual dependencies and opportunities for transformation. It outlines the increasing demand for electricity to support AI development, the role of AI in optimizing energy systems, and the policy and infrastructure considerations necessary to address these challenges.

Main Points

• AI and Energy Interdependence: AI is fundamentally dependent on energy, particularly electricity, and in turn, AI has the potential to transform the energy sector.
• Rapid Growth of AI Demand: Data centres, which host AI models, are driving significant electricity demand. By 2030, global data centre electricity consumption is expected to more than double to around 945 TWh, surpassing Japan's total consumption.
• Regional Variations in Demand: The United States is the largest contributor to data centre electricity demand, accounting for nearly half of the global increase. In contrast, data centres represent over 20% of electricity demand growth in advanced economies.
• Energy Sources for AI: Renewables and natural gas are the primary sources to meet data centre electricity demand, with SMRs and advanced geothermal also playing a role. The tech sector is supporting the development of these technologies.
• Infrastructure Challenges: The electricity grid is under strain, and delays in connecting data centres could occur. Strategies such as flexible operation and locating data centres in areas with high grid availability are proposed to mitigate these risks.
• AI for Energy Optimization: AI is already being used by energy companies to optimize operations, reduce costs, and lower emissions. Applications include fault detection, predictive maintenance, and grid management.
• Policy and Collaboration Needs: The report emphasizes the need for collaboration between policy makers, the tech sector, and the energy industry. It also highlights the importance of developing digital skills and fostering inclusive AI adoption in emerging economies.
• Uncertainties and Scenarios: The report presents several sensitivity cases to explore different scenarios of AI adoption and energy demand growth, including the Lift-Off Case, Headwinds Case, and High Efficiency Case.

Key Information

• Global Data Centre Consumption: In 2024, data centres accounted for approximately 1.5% of global electricity consumption, or 415 TWh.
• Projected Growth: By 2030, data centre electricity consumption is expected to reach around 945 TWh, and by 2035, it could range from 700 to 1,700 TWh depending on the scenario.
• Energy Demand Drivers: AI is a major driver of electricity demand, alongside other digital services. However, its impact varies by region and economic development.
• AI's Role in Energy Sector: AI can enhance energy system resilience, improve efficiency in electricity generation and transmission, and optimize energy use in industry, transport, and buildings.
• Sustainability and Affordability: The report stresses that reliable, affordable, and sustainable electricity supply is essential for AI development, and that countries capable of delivering this will have a competitive advantage.
• Collaboration and Innovation: The IEA recommends a three-pillar approach: a diversified energy mix, grid infrastructure investment, and enhanced dialogue between sectors. It also highlights the potential for AI to accelerate energy innovation through better data and faster development cycles.

Conclusion

The report underscores the critical role of energy in the development and deployment of AI, and the transformative potential of AI for the energy sector. It calls for proactive policy measures, cross-sector collaboration, and investment in infrastructure and digital skills to ensure the sustainable integration of AI into the global energy landscape.
