This annual Global Energy Outlook report examines a range of projections for the global energy system, summarizing key implications for global energy consumption, emissions, and geopolitics. The future of the global energy system is deeply uncertain, and the choices that are made in the coming years will have enormous consequences for the future of the climate and, indeed, human civilization. To understand how energy system is changing, each year various organizations produce long-term projections that imagine a wide range of futures based on divergent visions about policies, technologies, prices, and geopolitics.
