1. Thematic Context: Setting the Stage
Islands confront a paradox: abundant renewable potential, yet near-total dependence on imported fossil fuels. With limited land, high energy prices, and growing climate threats, geothermal emerges as a compact, reliable solution. It can deliver affordable, firm power, requiring up to ten times less land per megawatt than solar or wind plus storage.
2. Policy Spotlight: Caribbean Energy Sovereignty
For nations like Dominica, St. Kitts & Nevis, St. Lucia, and Montserrat, energy insecurity is a strategic vulnerability. Geothermal offers true resilience. Unlocking its potential demands regulatory clarity, risk-sharing instruments, cross-island cooperation, local capacity development, and access to climate financing. These pillars can enable island nations to cut import dependence, stabilize power costs, and build sustainable energy systems.
3. Tech Talk from Aotearoa
Jeremy O’Brien of Seequent took us to New Zealand – an island nation where geothermal now accounts for nearly 20% of electricity. With projects like Tauhara showcasing how advanced subsurface modelling and robust geological planning can scale clean energy with precision and societal impact. This model holds valuable lessons for island communities worldwide.
4. Workshop Preview: “Firm Power, Flexible Futures”
Given limited space and rising energy costs, islands need compact yet resilient solutions. Geothermal fits perfectly, delivering 24/7 baseload, cascading heat functionality, and lower volatility compared to diesel. That’s why IGA and the Greening the Islands Foundation are convening a high-level workshop on September 3. Stakeholders will explore modular geothermal deployments, financing models, policy tools, and broader social benefits like food and water security.
