This report was prepared by Allison Woodruff for the Regional Energy Officials Meeting in the Cook Islands 2007. The case studies were chosen in order to reflect as wide a range of renewable technologies as possible in a variety of different Pacific island settings. These include O’ua Island, which is part of the Ha’apai Solar Electrification Project in Tonga; the Bulelavata Micro-Hydroelectric Project in the Solomon Islands; the Welagi and Vanua Balavu Coconut Biofuel Projects in Fiji; and the Mangaia Wind Project in the Cook Islands.
