[en] Through 2012 and 2013, the World Energy Council (WEC) in partnership with the global management consulting firm Oliver Wyman, interviewed over 100 global energy leaders - chief executive officers (CEOs), senior executives, ministers for energy and the environment, senior policymakers, and regulators, as well as high-level representatives from inter-governmental organisations. The goal was to identify the necessary policies and regulation, industry actions, and barriers to the development of secure, affordable, and environmentally sustainable energy systems. Together, the interviewees represent an extraordinary body of energy industry knowledge, expertise and insights on what works and what does not work in terms of policy design and implementation. The research found many areas of broad agreement among public and private energy leaders on how to tackle the energy trilemma - the triple challenge of finding solutions that simultaneously support the three key aspects of energy security, energy equity, and environmental sustainability. This report, World Energy Trilemma: Time to get real - the agenda for change, sets out 10 areas for focused action identified in interviews and validated at a high-level dialogue in July 2013, in Paris (France). The challenge now lies in moving forward with all the necessary stakeholders, including the energy industry, consumers, citizens, the financial sector, policymakers, and regulators to put the agenda into action. The world's energy challenges are well known: responding to a predicted growth in primary energy demand of between 27% and 61% through to 20501; meeting the needs of the 1.2 billion people currently without access to electricity and the 2.8 billion people who do not have clean cooking facilities; investing in the update of ageing energy infrastructure; while reducing the environmental impacts of energy production and use. The pressing need to transform the energy system comes at a time when many governments are struggling with a significant debt burden and the lingering effects of the global recession. Maintaining a balance between the three legs of the energy trilemma can seem impossible. At the same time, there are huge opportunities ahead in the energy industry: recent shale gas discoveries have impacted on the dynamics of supply; technological and cost breakthroughs have accelerated the adoption of renewables; electricity generation from renewable sources is predicted to represent 25% of gross power generation by 20183; new technologies are increasing energy efficiency in transportation, buildings and appliances and decreasing the environmental impact of energy production and use; and the post-2015 millennium development goals constitute a renewed global focus on global energy access. We would seem to be at the point of a truly secure and sustainable energy future - if we can enact the required leadership. The 2012 and 2013 World Energy Trilemma reports and this Agenda for Change provide a strong call to action by leaders and peers in the energy community. The time to act is now: it is time to get real. This report sets out 10 agreed areas for energy leaders to focus policies and resources on, to capture the opportunities and meet the needs of citizens and consumers. The public and private sectors must collaborate to design and implement broadly supported mechanisms to drive this change. Is this collaboration possible? Are we at a tipping point to making real breakthroughs in meeting the energy trilemma? The WEC's World Energy Trilemma 2012-2013 research programme focused on how to break out of the current energy trilemma. Tapping into the insights of 100-plus global energy leaders resulted in the identification of 10 jointly acknowledged priority action areas. While many of these action areas have been highlighted by other organisations, the WEC's efforts uniquely capture the jointly identified priorities of global energy leaders from public and private sectors, and from developed, emerging and less developed nations. For political decision makers and the energy industry, this report is the Agenda for Change, a call to action by peers and colleagues. The World Energy Trilemma reports must serve as a catalyst in building honest and realistic debates, sharing best practice and fostering a clear vision for sustainable energy. The WEC, with its broad membership base, is ready and positioned to provide the platform and forum to drive forward the Agenda for Change
