Supplementary files for article "A whole island approach to scoping renewable energy sites and yields"Island communities are particularly vulnerable to climate change and energy in?security; renewable energy can counter both threats. This study takes a whole is?land approach to scoping wind and solar energy potential. The Isle of Man (IOM) was selected because of the limited development of renewables to date, plus high reliance on energy imports. Potential sites for renewables development were eval?uated using social, environmental, technical, economic and political factors in a combined Geographic Information System (GIS)-multi-criteria decision analy?sis (MCDA). We find that 9% of the island is highly suitable for onshore wind development, and 2% for solar photovoltaic. These areas could potentially yield 107MW from onshore wind and 150MW from solar. Roof top and floating solar could add a further 30MW, and offshore wind 497MW. The total wind and solar renewables potential of onshore and offshore sites of 784MW is much greater than the historical (85MW) and projected (131MW) demand by 2050. Hence, our first stage estimates suggest that combinations of renewables could signifi?cantly improve energy security and even support energy exports from the IOM. The demonstrated GIS-MCDA modelling offers a tool for scoping the resource potential of other energy-import dependent islands.© The Author(s).
