This document discusses fuel switching from diesel to coconut oil for rural electrification in Pacific Island countries. It notes that diesel currently accounts for a large portion of electricity costs due to transportation to remote areas. Coconut oil is proposed as an alternative that could displace a significant amount of diesel usage. Modifications would need to be made to engines and supply chains established, but initial blends of 20% coconut oil and 80% diesel are recommended. Fuel switching could save over $70 million annually while reducing greenhouse gas emissions by around 180,000 tonnes per year. Further analysis of supply chains is needed to implement this solution.
