World Energy Outlook 2022
About this book
World Energy Outlook 2022 International Energy Agency (IEA) en The World Energy Outlook 2022 (WEO-2022), published by the International Energy Agency, stands as one of the most consequential editions of this flagship annual report in decades. Released against the backdrop of an unprecedented global energy crisis triggered by Russia's full-scale invasion of Ukraine in February 2022, the report arrives at an inflection point for global energy systems. It offers a rigorous, data-driven analysis of current energy market conditions and charts multiple future pathways, arguing that the crisis — while deeply disruptive — carries within it the seeds of a faster, more durable transition to clean energy.
The report's central finding is that the world is experiencing its first truly global energy crisis, one of exceptional breadth and complexity. Russia had been the single largest exporter of fossil fuels in the world, and the severing of energy trade relationships — through Russia's curtailment of natural gas supplies to Europe and reciprocal Western sanctions on Russian coal and oil — sent energy prices to historic levels. Spot prices for natural gas at times reached the equivalent of USD 250 per barrel of oil.
High fuel prices accounted for roughly 90% of the rise in average electricity generation costs worldwide in 2022, making it unambiguously clear that this crisis was rooted in fossil fuel dependence, not in renewable energy deployment. To analyze future trajectories, WEO-2022 deploys three core scenarios. The Stated Policies Scenario (STEPS) models the energy system trajectory implied by governments' currently enacted policies and announced measures.
Under STEPS, global energy demand grows roughly 1% per year to 2030, met almost entirely by renewable energy additions, and for the first time in WEO history, every fossil fuel — coal, natural gas, and oil — peaks or plateaus in demand within the scenario's timeframe. Coal falls back within a few years; natural gas plateaus by the end of the 2020s; oil levels off in the mid-2030s as electric vehicle adoption accelerates. CO2 emissions in STEPS reach a plateau near 37 gigatonnes before declining slowly to approximately 32 Gt in 2050 — a trajectory consistent with around 2.5°C of warming by 2100.
The Announced Pledges Scenario (APS) assumes all governments' stated climate commitments — including net-zero pledges — are fulfilled on time and in full. Under APS, emissions peak in the mid-2020s and fall to 12 Gt by 2050, corresponding to a projected median temperature rise of approximately 1.7°C. The Net Zero Emissions by 2050 Scenario (NZE) works backward from the imperative of limiting warming to 1.5°C.
It requires CO2 emissions to fall to 23 Gt by 2030 and reach net zero by 2050. This pathway demands a tripling of clean energy spending — from around USD 1.3 trillion to above USD 4 trillion annually by 2030 — and an unprecedented mobilization of investment in solar, wind, energy efficiency, electric vehicles, and grid infrastructure. A major strategic theme of WEO-2022 is the realignment of energy security with the clean energy transition.
Historically, energy security arguments were used to justify continued reliance on domestic or imported fossil fuels. The 2022 crisis inverts this logic: dependence on fossil fuels has become the primary energy security vulnerability, while investment in local renewable resources, energy efficiency, heat pumps, and grid modernization simultaneously improves security and reduces emissions. The report documents a significant policy response underway in major economies — the U.S.
Inflation Reduction Act, the European REPowerEU plan, and accelerated renewable permitting across multiple jurisdictions — arguing these represent the foundations of an accelerating structural shift. Russia's diminished role in global energy trade is treated as a durable change. Its share of internationally traded natural gas, which stood at 30% in 2021, is projected to fall to 15% by 2030 under STEPS and to 10% in the Accelerated Policies Scenario.
This redrawing of the energy map accelerates the search for energy diversification and reinforces the economic case for domestic clean energy investment. WEO-2022 also grapples extensively with equity and access. The combined shocks of the COVID-19 pandemic and the energy crisis left approximately 75 million people unable to maintain access to electricity services and 100 million unable to afford clean cooking solutions.
The report stresses that just and people-centered energy transitions must address energy poverty as a priority, not an afterthought. It argues that clean energy investments in developing and emerging economies need to scale dramatically — and that the current mismatch between where capital flows and where it is needed represents one of the most critical structural obstacles to a global clean energy transition. The report provides policymakers with ten guiding principles for navigating the coexistence of declining fossil fuel systems and expanding clean energy infrastructure.
These include maintaining reliable supply during the transition, avoiding stranded asset risks, building out flexibility and storage in power systems, and ensuring that the social dimensions of transition — including workforce shifts — are managed proactively. Overall, WEO-2022 concludes with cautious optimism: the conditions for a decisive acceleration of clean energy deployment have never been stronger, but the window to align current momentum with 1.5°C-consistent pathways remains narrow and requires urgent, coordinated action.
