21th Conference on Sustainable Development of Energy, Water and Environment Systems (SDEWES)

The 21st Conference on Sustainable Development of Energy, Water and Environment Systems (SDEWES) is dedicated to the advancement and dissemination of knowledge on methods, policies and technologies for increasing the sustainability of development by de-coupling growth from the use of natural resources and by a transition to a knowledge-based economy. All taking into account the economic, environmental and social pillars of sustainable development.
