In this paper we identify the renewable energy source (RES) demand scenarios for Morocco, the needs of RES installed capacity according to those scenarios and the detailed investment plans needed to achieve such installed capacity supply. Then, using a dynamic variant input-output model, we simulate the macroeconomic impact of the foreign investment inflows needed to make available these Moroccan RES generation capacity plans in the medium and long term. The use of concentrated solar plants, photovoltaic generation and wind power farms are considered and compared in the simulation. (C) 2012 Elsevier Ltd. All rights reserved.
