Huang et al. [13] used various MCDM such as ELECTRE, AHP,
TOPSIS, etc. to conduct an analysis of the energy system. In 1997,
Georgopoulou et al. [14] studied the advantages and disadvantages
of the implementation of renewable energy in the Greek islands
using the ELECTRE III method. In Italy, Beccali et al. [15] used the
multi-criteria decision system to assess the different energy
alternatives. Haralambopoulos and Polatidis [16] applied PROMETHEE II to investigate and assess the exploitation of a geothermal energy source in the island of Chios (Greece). In 2004, Pohekar
and Ramachandran [17] applied MCDM to energy planning.
In southern Spain, in Andalusia, Terrados et al. [18] developed a
combination of methodologies (including MCDM) for a renewable
energy plan. More recently, Eunnyeong et al. [19] used the fuzzy
AHP methodology to evaluate a renewable energy program. In the
same year, Cavallaro [20] employed the Fuzzy TOPSIS approach for
assessing thermal-energy storage in a concentrated solar power
system.
