RT Journal Article T1 In-depth assessment of energy transition policies: a comparative study between Proinfa (Ceará, Brazil) and Law 8/2009 (Galicia, Spain) A1 Sousa, Nicole Stephanie Florentino de A1 Regueiro Ferreira, Rosa María A1 Cardoso, Gil Célio de Castro K1 Wind Energy K1 Public Policy Evaluation K1 Energy Justice K1 Ceará/Brazil K1 Galicia/Spain AB This article aims to conduct an in-depth comparative assessment of Incentive Programme for Alternative Sources of Electricity (Proinfa/Brazil) (with a focus on the implementation of the policy in Ceará) and the Galician Wind Energy Law (Law 8/2009), examining the extent to which these policy instruments have succeeded in reconciling sectoral expansion, territorial governance, and procedural and distributive justice. The analysis is grounded in the framework of in-depth public policy evaluation proposed by Rodrigues (2008) and adopts a qualitative and documentary approach to investigate the institutional trajectories and distributive impacts. The results indicate that, although both instruments have been effective in expanding installed capacity, significant distributive paradoxes remain. In Ceará, fragmented governance has intensified land conflicts in coastal areas, whereas in Galicia, centralised planning has resulted in high levels of litigation. The study concludes that the maturity of wind energy policy depends on moving beyond investment security to consolidate effective mechanisms for procedural justice and the democratisation of benefits.
