Traditionally renewable energy applications have a positive business case on smaller islands, because transportation costs are high. In addition, islands are particularly exposed to the consequences of global warming and many island communities strive to serve as an example in the fight against climate change.
Many of these bottlenecks actually do not reflect the reality today. There are solutions for external financing such as rental or power providers selling the energy to the island off-takers. On the technical side improvements of diesel generators will improve penetration as well as enhancements of hybrid controlling units.
