The document summarizes key findings from the World Energy Council's Global Scenario Study. It presents 3 scenarios for global energy development to 2060: Modern Jazz, Unfinished Symphony, and Hard Rock. The scenarios differ in assumptions around economic growth, policies, and technologies. Key findings include: 1) world primary energy growth peaks before 2030 due to new efficiencies, 2) electricity demand doubles requiring major infrastructure, 3) wind and solar continue rapid growth, 4) coal and oil demand peaks may create stranded resources, 5) decarbonizing transport is very challenging, and 6) a 2°C target requires unprecedented global cooperation and carbon pricing. The study was conducted by PSI using its Global MARKAL energy systems model
