The World Energy Council’s Energy Trilemma Index ranks countries’ energy performance on three dimensions, Energy Security, Energy Equity, and Environmental Sustainability, based on global and national data. The results show impacts of decisions and changes, suggesting where policy coherence and integrated policy innovation can help develop well calibrated energy systems in the context of the Grand Energy Transition.
Healthy energy systems are secure, equitable and environmentally sustainable, showing a carefully managed balance between the three dimensions. Maintaining this balance in the context of rapid transition to decentralised, decarbonised, and digital systems is challenging: there are risks of passive trade-offs between equally critical priorities.
The 2018 Energy Trilemma Index Report shows that many countries are managing the balance successfully, with eight nations achieving a top AAA balance score.
The Energy Trilemma once more ranks Denmark, Switzerland and Sweden at the top, recognising the well-balanced energy systems in these countries.
