RESUMO
O governo de Cabo Verde planeia ter 100% da geração de energia elétrica do país oriunda de fontes renováveis até 2025. Neste contexto, a interligação energética das ilhas cabo-verdianas mostra-se fundamental para minimizar a intermitência, inerente a estas fontes, e garantir a estabilidade do sistema elétrico. Esta interligação só é possível por meio de cabos de energia submarinos. Este artigo tem por objetivo verificar a viabilidade ambiental de interligar eletricamente as ilhas de Cabo Verde por meio de cabos de energia submarinos e identificar quais são as ilhas que apresentam os principais desafios ambientais para a instalação desses cabos. Isso é feito por meio do mapeamento das regiões costeiras e marinhas de Cabo Verde em que a instalação dos cabos submarinos pode ter um efeito crítico e irreversível no ecossistema local. Verifica-se que as maiores restrições ambientais estão nas ilhas de Santa Luzia, do Sal, de Boa Vista, de São Vicente e do Maio. Contudo, conclui-se que somente na Santa Luzia, uma ilha desabitada, a questão ambiental é um fator que inviabiliza a utilização dos cabos de energia submarinos na interligação elétrica das ilhas de Cabo Verde.
Palavras-chave: viabilidade ambiental, interligação energética, impacto ambiental, países insulares.
ABSTRACT
The Cape Verde government plans to have 100% of the country's electricity produced by renewable sources by 2025. In this context, the energy interconnection of the Cape Verdean islands is fundamental to minimize the effects of the intermittency, inherent to renewables sources, and guara1ntee the stability of the electrical system. This interconnection is only possible through submarine power cables. This paper's objective is to assess the environmental viability of interconnecting the islands and to identify which are the islands that present the main environmental challenges to the installation of the cables. This is done through the mapping of the coastal and marine areas in Cape Verde that can be critically affected by the impacts caused by submarine power cables. The main environmental restrictions are verified in the islands of Santa Luzia, Sal, Boa Vista, São Vicente and Maio. However, only in Santa Luzia, an uninhabited island, the environmental factor makes it unfeasible to install submarine power cables for the electric interconnection of the Cape Verde's islands.
