The Energy Trilemma Index ranks countries in terms of their likely ability to provide sustainable energy policies through the 3 dimensions of the energy trilemma:
1. Energy security: the effective management of primary energy supply from domestic and external sources, the reliability of energy infrastructure, and the ability of participating energy companies to meet current and future demand.
2. Energy equity: the accessibility and affordability of energy supply across the population.
3. Environmental sustainability: the achievement of supply and demand-side energy efficiencies and the development of energy supply from renewable and other low-carbon sources.
The Index rank measures overall performance and the balance score highlights how well a country manages the trade-offs between the three competing dimensions: energy security, energy equity, and environmental sustainability.
The best score ‘A’ is given for a very high performance. Countries with good results are awarded with the score ‘B’. High performers receive the score ‘AAA’ while countries that do not yet perform well receive a ‘DDD’ score.
