This report analyzes in detail the potential contribution to the island tourism sector of four renewable energy technologies (RETs): 

1. Solar water heating (SWH) systems use solar heat to warm up domestic water, usually replacing electric water heaters.
2. Solar air conditioning (SAC) systems use solar heat to provide cooling and heating, usually replacing traditional electric chillers.
3. Sea water air conditioning (SWAC) systems use cold water from the ocean depths to provide air conditioning in hotel rooms and facilities, usually replacing traditional electric chillers.
4. Solar photovoltaic (PV) systems produce electricity from the sun, usually replacing diesel generated electricity, either purchased from the local power grid, or self-produced with private diesel generators
