This report examines pathways for advancing renewable energy and decarbonization in Brazil, analyzing three scenarios: Business as Usual, expanded Distributed Generation Photovoltaic (DGPV) adoption, and increased electric vehicle (EV) use. Key findings highlight the importance of financial incentives for DGPV expansion, with a 35% cost reduction in solar technology expected to have a significant impact by 2042. A projected 20% increase in EVs by 2050 would contribute to a 20% emissions reduction with minimal strain on the electricity system. The report recommends long-term policy planning, integrated renewable energy and transportation policies, and further research on EV adoption and implementation challenges.
