The World Energy Trilemma 2017 report Changing dynamics – Using distributed energy resources to meet the Trilemma challenge, prepared in partnership with global consultancy Oliver Wyman, along with the Global Risk Centre of its parent Marsh & McLennan Companies, tapped into the global insights of the traditional and emerging players in the electricity sector – including policymakers, regulators, traditional utilities, large consumer/ prosumers, and technology providers –to capture a wide range of views on the evolution of the energy sector. The report identifies key focus areas for regulators and policymakers in the context of balancing the Energy Trilemma and driving forward progress on each dimension of the energy trilemma. The electricity sector is undergoing change at an unprecedented pace with the growth in distributed generation enhancing trends in decentralisation and decarbonisation, opening new opportunities and challenges for countries to balance the energy trilemma.
