This paper aims at critically analyzing the present and the proposed energy resource mix in Mauritius in order to make recommendations for a 100% renewable energy system for the island by 2050. While the Long Term Energy Strategy for the period 2009–2025 devised by the Government of Mauritius sets pathways for the future in a sustainable manner, it does not evaluate the feasibility of the options that will help in supporting this transition. Its scope is limited as the proposed framework aims at achieving only 35% self-sufficiency in terms of electricity supply by 2025 against 20% currently. This paper explores the main building blocks of a new energy paradigm by extending the analysis to 2050 in view of identifying systemic and holistic policies and strategies that will pave the way to a clean and efficient energy supply. Most notably, we look beyond electricity only to assess the energy system comprehensively in terms alternative resources for primary uses, including energy-intensive transportation and cooling. Ultimately, it also enhances the near-term energy framework by setting more ambitious green energy targets as a stepping-stone towards 100% energy self-sufficiency by 2050.
