Centre for Energy and Environment aims to find sustainable solutions to global energy inadequacy and environmental degradation as the global energy systems will experience major changes in coming decades. These challenges call-for scientific knowledge, innovative-technology development, policy measures and action at local and world level. The sustainability of the system will prove to be of prime importance environmentally, economically and socially.Although the fossil resources have been fundamental source of energy for human existence since long time in everyday life and now the time of oil discoveries are almost over. Addressing the challenges arising from issues of energy scarcity will involve a massive increase in the utilization of sustainable energy resources like wind, solar and biomass. This transformation will not take place overnight but decades. For this reason, high priority to use renewable energy systems and energy efficient buildings should be given. Centre of Energy and Environment shares the knowledge and research at the scale of individual components as well as of large-systems, with a focus on the interaction between these two. Centre is at the cutting-edge in northwest India when it comes to research in renewable energy systems. Through wide-ranging team-work and partnerships with the private, public sectors as well as national and international collaborators and responsibilities in the policy process, centre is living up to the ambition.
