Decision support methodology for sustainable smart energy systems integration

The global demand for energy is continuously increasing, and the carbon dioxide production related to the energy sector represents a large share of the overall anthropogenic greenhouse gas (GHG) emissions, since most of the energy needs are still provided by fossil fuels. To achieve the energy efficiency targets set by EU for the 2030 an energy transition towards more sustainable energy sources is required. The challenge will be the integration of different energy sectors in a smart energy system (SMES). Adopting a circular economy perspective it will be possible to turn the view on waste starting considering them as an energy source allowing more interactions between different stakeholders while exploiting technologies for the reduction of the environmental impact. This change in perspective needs also a change in the paradigm while taking decision on the implementation of this kind of interventions. The aim of this thesis is to fill the gaps in the development of decision support tools aiding the stakeholders in those interventions where SMES are implemented with developing and sustainable solutions.
