A Delphi study was conducted to determine the social acceptance level and problems in the utilisation of renewable energy sources for different end-uses. The Delphi questionnaire was prepared for solar, wind and biomass energy applications, considering economical, technological, social and environmental factors. The questionnaire was sent to various participants such as academicians, industrialists, scientists, policy makers and other users. The responses were analysed using mean, standard deviation, confidence, skewness and rank correlation techniques. Stability and consensus analysis were conducted on the Delphi results, and it was found that in 97.9% of the cases there was consensus, and in 100% of the cases there was group stability, while in 95% of the cases there was individual stability. The study revealed that the percentage energy distribution for solar, wind, biomass and commercial energy sources are expected to be 7.12%, 7.9%, 10.49% and 74.49%, respectively, by the year 2020.
