Vanuatu has integrated wind and coconut oil into the fuel mix of its electricity generation, but other countries have not had similar success with integration of these particular types of renewable energy sources. In addition, electricity grids can be developed in such a way that allows for the adoption of emerging technologies (marine energy, electric vehicles) in the future. The current and future use of smart grids and electric vehicles in developed countries and other island regions should be closely monitored for potential replication in the Pacific at the appropriate time. As the diffusion of grid-connected solar PV technology and wind turbines, for example, has largely trailed the adoption and dissemination of those technologies in developed countries, Commonwealth Pacific small states should not expect the latest sustainable energy technologies to be implemented before, or at a quicker rate than, these technologies have been adopted in more developed countries.
