Executive Summary -- Introduction -- 1. Time for action and an ambitious climate framework -- 2. 2015 Energy Trilemma Index -- 3. Regional profiles -- 4. Cross-regional profiles -- 5. Country profiles -- Appendix A: Index methodology and balance score.

Now in its fifth edition, the 2015 Index shows signs of progress for all dimensions of the energy trilemma, although it remains a struggle for most countries to develop a balanced approach, with only two countries out of 130 obtaining a ‘AAA’ balance score. While the transition towards sustainable, balanced energy systems is slowly occurring, progress can be sped up by creating robust and stable policy frameworks. In the run-up to the 21st Conference of the Parties (COP21), the Index supports the messages from the World Energy Council welcoming the bottom-up ‘Intended Nationally Determined Contributions’ process and emphasising the need for strong national energy policy frameworks based on a trilemma approach to effectively implement international objectives. The 2015 World Energy Trilemma priority actions on climate change and how to balance the trilemma report recommends a meaningful agreement supported by a focus on clearly identified action areas that enable and accelerate the transition towards low-carbon energy systems.
