Surging electricity demand from AI, data centres and industrial electrification is colliding with geopolitical instability, mounting infrastructure constraints and persistent energy and development gaps, exposing new pressures across the global energy system, according to the World Energy Council’s 2026 World Energy Trilemma report.
Launched today to coincide with Climate Week NYC, the report 'Rebalancing World Energy: Trade-Offs and Transformations' finds that recent disruption to energy flows through the Strait of Hormuz, alongside rapidly growing demand from digital infrastructure, is accelerating a wider rebalancing of world energy. The challenge is shifting from deployment alone to integration and interoperability - while simultaneously navigating energy security, affordability, decarbonisation, industrial competitiveness and the unfinished agenda of energy access and human development.
The report describes this as 'rebalancing': the leadership discipline of continually reassessing energy security, equity and environmental sustainability as circumstances change. In practical terms, this means adding new generation and connecting it with grids, storage, flexible demand, markets and institutions—while enabling different technologies and national pathways to work together. Integration makes the parts of an energy system work as a whole; interoperability enables different systems and pathways to work together.
Drawing on dialogue with more than 275 senior energy leaders from 65 countries, the report finds that the trade-offs at the heart of energy transitions have not disappeared but are moving into new parts of the system. Across regions, leaders identified grids, storage and system integration as the most common constraints on progress.
Dr Angela Wilkinson, Secretary General & CEO of the World Energy Council, said: 'World energy is being rebalanced in real time. Our World Energy Trilemma report shows how the electrification surge, geopolitical disruption and persistent development gaps are creating harder choices across grids, storage, markets and institutions. Integration and interoperability are now critical: connecting the parts of each system and enabling different systems and pathways to work together. Leadership means continuously rebalancing security, affordability and sustainability while keeping sight of what energy is ultimately for - better lives and stronger economies.'
The report identifies five recurring tensions: investing for tomorrow while managing today’s costs; redesigning markets while operating within current realities; strengthening national competitiveness while preserving cross-border interdependence; maintaining speed of transitions while earning social legitimacy; and matching institutional ambition to the capacity available.
Regional examples show how these pressures are taking different forms:
- In Africa, around 600 million people remain without access to electricity, demonstrating that expanding generation is only part of the challenge. Progress also depends on transmission, finance and effective delivery systems.
- In Saudi Arabia, ambitions to achieve a 50% renewable power mix by 2030 are increasing the focus on how renewables, storage and flexible gas generation can work together, illustrating how successful transitions increasingly depend on combining technologies within a flexible, integrated energy system.
- In China, nearly 50 ultra-high-voltage transmission projects delivering over 420 GW of cross-regional capacity demonstrate the scale of infrastructure required to show how system integration has become essential to connecting renewable resources with industrial and population centres.
- In Brazil, a power system that is around 90% renewable is facing rising curtailment, illustrating how the next phase of the transition depends on integration across generation, storage, markets and demand-side flexibility.

About the World Energy Council
The World Energy Council is the world's oldest independent and impartial community of energy leaders and practitioners. Through our Humanising Energy vision, we involve more people and communities in accelerating clean and inclusive energy transitions in all world regions. Formed in 1923, the Council is a UN-accredited global energy body that has convened diverse interests from across the full energy ecosystem for more than a century, and today has over 3,000 member organisations and a presence in more than 100 countries. Our global network draws from governments, private and state corporations, academia and civil society, as well as current and future energy leaders. We collaborate on impact programmes and inform local, regional and global energy agendas in support of our enduring mission: to promote the sustainable use and supply of energy for the benefit of all people.
