In recent years, demand for energy has increased enormously. This inexorable increase has placed immense pressure on supply, augmented by geopolitics, fierce weather conditions and other potentially troublesome factors which have been reflected in the global scenario through environmental issues and soaring prices. The global community has identified this as a grand challenge and massive research is going on in this direction. ICESA-2015 aims at the state of the art technologies to meet this specific grand challenge. It is a technical congregation which emphasizes on latest theoretical and technological advances and provides a forum for academicians, scientists, researchers, engineers and industrialists from various energy disciplines to exchange ideas. It also provides a multidisciplinary platform to present the latest trends, sustainability, practical challenges encountered and the solutions implemented. We anticipate that this conference will be a trigger for further related research and novel ideas to address the grand challenge.
