The IICEC Energy and Climate Research Review provides an organized overview of recent energy policy research. The Review includes 68 studies and papers that collectively address global energy security, affordability and sustainability and shed light on the energy debate by illuminating its complexities. With the gravity of the challenge in mind, the Review intends to capture the complexity of the energy debate from as many angles as possible bearing in mind that energy is a multi-disciplinary domain which requires in-depth analysis. The Review is organized by energy sectors and themes namely: fossil fuels, nuclear power, renewables, efficiency measures, energy technology and innovation, as well as climate policy and regional economies. We intend that the Review can efficiently provide energy professionals the benefits of many of the most important policy studies that they might not otherwise have the time to consider. We aim to foster to a wider appreciation of the global energy policy agenda by making these research studies more accessible. The articles and reports in this Review have been selected considering their worldwide recognition, relevance, inclusiveness, originality, and the level of contribution to the policy agenda. Rather than providing a conclusive assessment and dictation of set of energy policies, the Review provides the reader with an opportunity to approach and analyze the articles, reports and policy papers from different perspectives.
