The APEC Peer Review on Energy Efficiency (PREE) responds to the declaration at the 9th APEC Energy Ministers Meeting (EMM9) in Fukui, Japan to promote the energy efficiency of the APEC member economies and meet the APEC's aggregate energy intensity reduction goal of 45% by 2035. PREE Phase 13 has two parts. The first part is the Energy Efficiency Policy (EEP) Workshop and the second part is the Follow-up PREE (FuPREE), which is designed to assist a former PREE host economy in implementing the recommendations of the PREE review team. The FuPREE in Chile was held from 6-10 May 2024. It was a 5-day workshop with a comprehensive discussion on energy efficiency with representatives and experts from the government ministry, regulator, and relevant agencies. As a result of the review, 31 challenges and 33 recommendations have been identified, which may facilitate the development of an energy efficiency policy and program to effectively achieve the energy efficiency goal of Chile.
