The government of Palau has proposed a target of achieving 100% of its electricity generation from renewable energy sources by 2050. This renewable energy roadmap for the Republic of Palau has subsequently been developed by the International Renewable Energy Agency (IRENA) at the request of the Ministry of Public Infrastructure, Industries and Commerce (MPIIC). The report charts the way forward to 2050 for the country’s power and transport sectors. It looks in detail at the current power sector and provides a pathway for achieving a fully decarbonised, least-cost power system, with intermediate milestones. Additionally, it also encompasses renewable energy options for the marine and road transport sectors.
