Descrição

Renewable energy technologies are part of the solution to meet future increasing demand of electricity and decommissioning of power plants in the European Union. Public opinion surveys indicate general support of these technologies, but particular projects face local opposition, a phenomenon known in the literature as the NIMBY (Not In My BackYard) hypothesis. In this study, the public opinion on renewable energy technologies was analyzed by means of a survey implemented in Portugal. The survey addresses four technologies: hydro, wind, biomass and solar power. The study has three main purposes: firstly, to recognize if the people acknowledges the existence of these technologies, secondly, to study the validity of the NIMBY hypothesis in Portugal while realizing in which technology it is more pronounced, and thirdly to perceive the levels of acceptance of each technology, under Sustainable Development aspects (Economy, Ecology and Society). The results suggest that acknowledgement of technology decreases with age, increases with educational degree and is greater in males. There is a generally positive attitude towards new projects of all technologies, and this tendency is more pronounced for solar power. Solar power plants are regarded by the Portuguese public as the most desirable technology in terms of economic and environmental aspects, while hydro power is perceived as the RES technology that can contribute the most to local residents’ welfare.
