Successful renewable energy deployment in Europe has been dependent on the combined effect of different support measures, rather than any one factor, says a report by the European Environment Agency (EEA). The report looks at the penetration of four renewable technologies: wind, biomass, photovoltaics and solar thermal. It examines how policies, legislative support, grid access, fiscal and financial support, technological development, and public information have influenced the technologies in each member state. "This report helps point the way towards solutions," says the EEA's Domingo Jiménez-Beltrán. "It demonstrates the EEA's determination not only to provide information to support better policy-making but also to gather 'best practice' information for actors on the ground to use."
