The 2019 World Energy Trilemma Index Report, developed in partnership with Oliver Wyman, provides an objective rating of national energy system performance across the three Trilemma dimensions. The Index demonstrates the impact of varying policy pathways countries have taken in each of the dimensions over the past 20 years. Ten countries achieve the top AAA balance grade in the 2019 World Energy Trilemma Index, representing top quartile performance in every dimension. Overall Trilemma performance for 119 countries over the 20-year period has improved, with only 9 countries seeing their overall performance declining. The rate of improvement in overall Trilemma performance also increases as the transition progresses and encourages countries to improve their energy policies.
