During the revision process for its NDC, the Government of Antigua and Barbuda proposed a target of achieving 100% of its energy generation from renewable energy sources by 2030. This renewable energy roadmap has subsequently been developed by IRENA at the request of the Ministry of Health, Wellness and the Environment. Five scenarios have been analysed, together with multiple renewable energy options including utility-scale solar PV, distributed solar PV, utility-scale wind, and green hydrogen. Meanwhile, electric vehicles (EVs) are considered for achieving a 100% renewable transport sector by 2040. The Roadmap also outlines various policy recommendations that will be crucial for the implementation of these scenarios.
