Abstract
The formulation and evaluation of renewable energy policies is a burning subject matter all over the globe. Policy
makers seek to cautiously perceive information from the renewable energy market place so as to determine the
dynamic factors, variables and policy parameters that influence the design of renewable energy policies. The
perceived information is often imprecise or fuzzy, which makes policy formulation difficult. This paper presents a
framework for evaluating renewable energy policies based on a fuzzy system dynamics (FSD) paradigm. First, we
describe the renewable energy policy problem, with a case study example. Second, we present a framework for FSD
modeling. Third, we propose a high-level causal loop analysis to capture the complex dynamic interactions among
various energy demand and supply factors, from a fuzzy system dynamics perspective. Fourth, and finally, we
propose an FSD model for renewable energy policy formulation and evaluation.
