Foreword Roberto BoccaHead, Centre for Energyand Materials; Member,Executive Committee,World Economic Forum Muqsit AshrafGlobal Strategy Lead,Accenture Today’s transition is not linear. Energy systems arebeing restructured in response to diverging nationalpriorities, and decentralization and digitalizationare creating new supply and consumption models.Elsewhere, industrial policy, energy sovereigntyand mineral security have come to the forefront.These shifts do not displace climate ambition butincreasingly embed it within broader goals forresilience, competitiveness and development. The 2025 edition of theFostering Effective EnergyTransitionreport arrives amid growing geopolitical,technological and climate-related disruption. Rather than a single transition, the world isundergoing a broader transformation – redefininghow energy is produced, consumed and governed.This is being driven by mounting climate risks,accelerated innovation, fractured global cooperationand rising pressure to deliver reliable, affordable andlow-emission energy systems. Looking ahead, transformation will require morethan innovation. Energy systems must be resilient,flexible and able to scale clean technologies,improve efficiency, secure critical inputs and reduceemissions from legacy infrastructure. Setting targetsis no longer enough – capacity for delivery must beactively built amid global uncertainty. The Energy Transition Index (ETI) offers a long-term view of how energy systems evolve acrosscountries, building on 15 years of energy transitionbenchmarking at the Forum. Early progress,particularly in Europe, was fuelled by climateambition, falling renewable costs and growingpublic support. In many emerging and resource-rich economies, energy security and equity weremore pressing. Over time, national priorities haveexpanded, with strategies increasingly shapedby supply chain resilience, industrial policy andcompetitiveness goals. Technologies like artificial intelligence (AI), advancedstorage and decentralized infrastructure areaccelerating change but also increasing pressure onpower systems, supply chains and regulation. AsAI, quantum computing and industrial digitalizationevolve, countries must harness their potentialwithout overwhelming already-strained systems. The 2025 ETI reflects this evolving reality. Cleanenergy investment surpassed $2 trillion, and 65%of countries improved their performance. Yetprogress remained uneven. Advanced economiesand emerging Europe focused on infrastructureand grid upgrades, while emerging Asia advancedthrough rising investment and innovation, andSub-Saharan Africa improved most in regulationand policy. Systemic constraints – from limitedinstitutional capacity to financing and infrastructurebarriers – continued to hamper progress, especiallyin low-income economies with fast-growing demandand constrained capital access. There is no single blueprint. Countries will followdifferent paths at different speeds. Ensuring adurable and inclusive transformation requiresalignment between ambition, finance and delivery –guided by market signals, grounded in local realitiesand supported by international cooperation. The 2025 ETI offers a data-driven tool to align ambitionwith action and build more resilient, equitable andsustainable energy systems. Developed with Accentureand key data partners, it reflects shared insights intoglobal energy challenges and opportunities. Executive summary There is growing progress towards a secure,equitable and sustainable energy system,but momentum could stall amid financingand geopolitical challenges. In 2024, there were underlying vulnerabilitiesacross energy supply chains and markets,combined with record energy demand. Regional dynamics reinforce the multi-speednature of the transition.
