Nowadays, policy makers have become more aware of renewable energy
advantages. From national and regional decision makers' points of view,
the  first  priority  is  preparing  comprehensive  energy  planning  and  the
second  is  determination  of  renewable  segments  in  total  energy
production plan. For selection, different alternatives among renewable
energy,  environmental,  economical,  technical,  and  social  criteria  were
combined.  As  a  matter  of  fact,  that  multi-criteria  decision  making
atmosphere can be shown. In recent years, a number of articles on the
subject of multi-criteriadecision making methods were published. Given
that, it is not possible for everyone to study the whole of related articles
in one hand, and on the other hand selection of an appropriate method
always needs deep analysis, this paper aims to compare different methods
in  order  to  achieve  a  general  overview  of  the  applications  of  MCDM
methods  in  renewable  energy  planning.  At  the  end  of  this  study,
PROMETHEE is proposed as the most appropriate method for renewable
energy planning.
