Brazil’s Artisanal Fishermen Turn to Solar Power

Artisanal fishermen in Rio de Janeiro state, Brazil are installing solar panels on their boats. They are replacing diesel and gasoline generators used to power lights for nighttime squid fishing. Two initiatives, SustentaMar in Arraial do Cabo and Pescando Sol in São Francisco de Itabapoana, funded by the Brazilian Biodiversity Fund (Funbio), are driving this change.

Together, the projects have equipped 285 fishing boats with solar technology, reducing pollution, noise, and fuel costs. Fishermen report increased boat autonomy, improved safety, and more free time due to eliminating battery charging runs. Paulo Henrique do Rosário Correia, a local fisherman, stated he “gave up” on generators due to pollution and noise.

The projects also include battery charging stations and environmental education. While initial skepticism slowed adoption in some areas, the benefits are encouraging more participation. Expanding the program depends on securing continued funding, community mobilization, and supportive public policies.
