Thus, we urgently need technologies and strategies for clean energy, water and environment that are free from green house gases and hazards posing threats to the lives of our next generation. The objective of WEES2020 is to discuss future technologies and strategies to make the world more livable for humans through sharing of knowledge and dissemination of ideas on technically feasible methods for maintaining balance of water and energy resources, preventing pollution of water resources, remediation of environmental pollution and for meeting up energy crisis both on local and global perspectives in a sustainable manner. From development of new materials to designing of devices, systems, technologies and policies for sustainable energy, environment and water will all be covered within the scope of this conference through mutual interaction of the scientists, engineers, industry professionals, policy makers and students working across theglobe in areas of clean energy, water and environment research.
