1. Acronimo per Renewable Energy Sources (fonti di energia rinnovabili)
  2. Acronimo per Reference Energy System e che indica la rappresentazione formale del sistema energetico all’interno di modelli come quelli di classe MARKAL e TIMES.


The Reference Energy System (RES) is a network representation of all of the technical activities required to supply various forms of energy to end-use activities. Analytical techniques are described to examine all operations involving specific fuels including their extraction, refinement, conversion, transport, distribution, and utilization. Each of these activities is represented by a link in the network for which efficiency, environmental impact, and cost coefficients may be specified. The network is quantified for a given year with the level of energy demands and the energy flows through the supply activities that are required to serve those demands. …”
