Environmental indicators deal with the environmental compat- ibility of the energy project with the surrounding territory and environmental science [59]. Environmental indicators must be focused on reducing the side effects caused by inefficient energy use and the energy supply chain,i.e. GHG emissions, biodiversity, noise, landscape, landuse, air pollution and depletion of natural resources, etc. [53,60]. In the light of climate changes and energy security issues, there are strongly needed environment friendly policies are required in energy planning and management [60]. Environmental indicators are given as follows:
