The Energy Transition Index’s analytical framework is designed to track country‑level energy transitions. It takes the energy sector’s wide range of roles within a country’s economy into account, along with its supporting regulations, markets and technologies.16 This allows for following the evolving energy system performance as measured by the system’s ability to support inclusive economic development and growth, secure and reliable access to energy, and environmental sustainability (the energy triangle).
Strong energy system performance is due to several energy transition readiness factors, including the availability of investment and capital, effective regulation and political commitment, stable institutions and governance, supportive infrastructure and innovative business environment, human capital, and the maturity and fixed assets that make up the existing energy system’s structure. Figure 1 summarizes the energy system performance and transition readiness dimensions.

The 2019 Energy Transition Index (ETI) provides scores for 115 countries spanning the many dimensions of energy transition performance and enablers. The Index delivers country‑level composite scores that aggregate 40 energy transition indicators over these dimensions; this includes integrating information from trustworthy data sources that describe country levels of energy pollution, prices, supply chains, infrastructure, political institutions, financial systems, human capital and more. Country‑specific scores are derived by normalizing the individual indicators and applying a weighting framework (see Appendix 1). The country rankings are presented next, with scores on system performance and transition readiness rounded to the nearest whole number. A full list of indicator data sources is provided in Appendix 2.
