Appraisal of the efficiency of subsidies granted by spanish public authorities for generating electricity using wind energy

Abstract

This paper aims to analyze efficiency of the subsidies granted by the Spanish authorities. The case study focuses on wind-generated electricity. We will study what type of subsidy is most efficient considering the economic and technical data of an existing wind power installation in Spain. A sensitivity analysis is made in order to provide judgment elements to propose the form of the more convenient subsidy. In view of the results obtained, we will evaluate the efficiency of subsidies granted by Spanish authorities.
