World Energy Outlook 2023
About this report
The World Energy Outlook 2023 provides in-depth analysis and strategic insights into every aspect of the global energy system. Against a backdrop of geopolitical tensions and fragile energy markets, this year’s report explores how structural shifts in economies and in energy use are shifting the way that the world meets rising demand for energy.
This Outlook assesses the evolving nature of energy security fifty years after the foundation of the IEA. It also examines what needs to happen at the COP28 climate conference in Dubai to keep the door open for the 1.5 °C goal. And, as it does every year, the Outlook examines the implications of today's energy trends in key areas including investment, trade flows, electrification and energy access.
This flagship publication of the International Energy Agency is the energy world’s most authoritative source of analysis and projections. Published each year since 1998, its objective data and dispassionate analysis provide critical insights into global energy supply and demand in different scenarios and the implications for energy security, climate change goals and economic development.
The Global Energy and Climate (GEC) Model key input dataset includes selected key input data for all three modelled scenarios (STEPS, APS, NZE). This contains macro drivers such as population, economic developments and prices as well as techno-economic inputs such as fossil fuel resources or technology costs.
