Over the past decade, the renewable energy landscape globally has undergone significant transformations. Driven by the need for energy security, national goals, and a push toward net-zero emissions by 2050, the sector has seen substantial shifts. Geopolitical conflicts, such as the Russia-Ukraine war, and rising tensions in the Middle East have intensified concerns about energy security in a world where energy demand continues to grow. This research seeks to identify the factors that have transformed the Brazilian renewable energy sector and to explore potential areas for future investment.
