In 2018 a household electrical appliances and lights survey were undertaken in the urban areas of Palau, i.e. Koror and Airai. The survey covered 40 urban households that have received an energy efficiency loan from the National Development Bank of Palau (NDBP) and a control group of 442 urban households that have not received an energy efficiency loan from the NDBP. The control group constitutes around 11.4% of all urban households in the country (as per 2015 census results there is a total of 3884 urban households in Palau). The survey was supported financially and technically by IUCN Oceania and the UNDP Pacific Office in Fiji. Data entry was done by the Palau Energy Administration (PEA), Government of Palau and data validation and tabulation was undertaken by the UNDP Pacific Office in Fiji.
