The report analyzes the energy transition of the Galápagos Islands, focusing on the total elimination of fossil fuels by 2040. It evaluates four demand sectors—residential, commercial/public, land transport, and maritime transport—and proposes three levels of policy ambition (Low, Medium, and High). Key strategies include replacing LPG with induction stoves and solar water heaters, electrifying land transport, and implementing a mix of slow steaming, wind-assisted propulsion, and biofuels for the maritime fleet. On the supply side, the report models the transition to 100% renewable electricity using solar PV, wind, Concentrated Solar Power (CSP), and geothermal energy. It concludes that while technological substitutions are generally cost-effective, structural infrastructure changes in buildings are not. The report also highlights the role of national subsidies and proposes an 'Eco Tax' for tourists to fund the transition.

• The residential sector's energy demand is split almost equally between electricity and LPG, with food cooking accounting for nearly 50% of household demand.
• Replacing LPG stoves with induction stoves is highly cost-effective, with a projected net accumulated saving of 21 million USD.
• Sustainable building interventions for existing homes are not cost-effective because the high implementation costs outweigh the energy savings, as these measures only impact about 10% of final household electricity demand.
• In the commercial and public sector, technological substitutions for LPG (solar water heaters and induction stoves) are beneficial, but infrastructure improvements for thermal envelopes do not compensate for their costs.
• The land transport sector is the second largest consumer of fuels in the islands. The 'High' policy scenario achieves zero fossil fuels by 2040 through a total conversion of the vehicle fleet to electricity and biodiesel.
• The maritime sector is the highest energy consumer. The 'High' impact scenario reduces energy demand by approximately 53% and greenhouse gas (GHG) emissions by 95% compared to the reference scenario.
• The maritime transition strategy includes slow steaming, sails, main engine efficiency, solar panels for auxiliary engines, LNG, marine biofuels, and electric propulsion.
• The electricity supply transition targets 100% renewable generation by 2040 (Low), 2035 (Medium), or 2030 (High), utilizing solar PV, wind, CSP, and geothermal energy.
• A proposed 10 MW geothermal plant in Isabela with a submarine interconnection to Santa Cruz was found to be partially oversized, leading to significant energy curtailment and an incremental present value cost of 26 million USD.
• The Ecuadorian state provides approximately 14 million USD annually in energy subsidies for the Galápagos province, primarily for fossil fuels and electricity.
• The report proposes an 'Eco Tax' for tourists to fund the transition; a contribution of approximately 2.5 USD per person-day could cover the incremental investment costs for the 'Low' ambition scenario.
