Energy From The Ocean : Liberating Tropical Islands from Fossil Fuels
Introduction
The recent signing of the High Seas Treaty has brought much-needed attention to the protection of our oceans.
As we strive to achieve sustainable development goals, it is crucial to explore untapped resources, such as ocean energy.
With the potential to provide renewable electricity and reduce dependency on fossil fuels, ocean energy holds the key to liberating tropical islands from the burden of expensive and environmentally harmful energy sources.
In this article, we will delve into the concept of ocean thermal energy conversion (OTEC) and its potential to revolutionize power generation in these regions.
The Significance of Ocean Energy .

The ocean, covering a vast surface area, holds immense potential for harnessing renewable energy.
The equatorial regions, in particular, store a significant amount of heat energy in the upper layers of the ocean.
Each day, tropical seawater absorbs an astounding amount of solar energy, which remains largely untapped.
By utilizing this abundant resource, we can reduce our reliance on fossil fuels, avoiding economic costs and mitigating environmental damage.
Ocean Thermal Energy Conversion (OTEC) .

One promising technology that can unlock the potential of ocean energy is Ocean Thermal Energy Conversion (OTEC).
This innovative approach utilizes the ocean as a “battery” to generate renewable electricity.
By harnessing solar heat energy absorbed by the ocean, OTEC eliminates the need for oil, gas, or coal. This not only reduces costs but also stabilizes electricity prices, making it an attractive solution for small island nations facing frequent blackouts and economic shocks.
Energy Prices in the Caribbean .
The Caribbean region heavily relies on imported fuels for electricity generation, resulting in high energy prices.
With an average electricity cost of around US$0.25 per kWh, some countries in the Caribbean pay over US$0.40 per kWh.
This dependence on imported fuels poses economic challenges and compromises energy security.
OTEC offers a viable alternative by halving diesel costs, providing a stable price point for electricity generation, and freeing up funds for critical climate mitigation and adaptation projects.
Suitability of Jamaica for OTEC .
Jamaica, with its tropical climate and expansive ocean surface area, is well-suited for OTEC implementation.
Currently, the country generates approximately 89% of its energy from fossil fuels.
By embracing OTEC, Jamaica can diversify its renewable energy capacity, reduce fuel imports (which account for 7.4% of GDP), and achieve its sustainability goals.
Previous studies have identified potential areas, including Kingston, Negril, Lucea, Port Maria, and Port Antonio, for OTEC implementation.
With ongoing developments in other parts of the world, Jamaica can learn from successful OTEC projects and pave the way for a greener future.
Overcoming Hurdles for Renewable Energy on Islands .

Islands face several significant hurdles when transitioning to renewable energy sources.
One major challenge is the limited landmass available for large-scale industrial power sites.
Many islands heavily rely on tourism, and unobstructed sea views are economically valuable.
To overcome this obstacle, microgrids and virtual power plants (VPP) offer a decentralized approach to energy generation.
With microgrids, communities can share power from rooftop solar systems, reducing the need for extensive land use.
The flexibility of microgrids allows them to connect and disconnect from the larger grid, ensuring a constant power supply.
The Role of Money in Renewable Energy Transition .
Finance plays a crucial role in the successful deployment of renewable energy solutions.
The cost of renewable technologies often fluctuates between being too expensive and too affordable to attract significant investment.
To overcome this challenge, countries need to explore creative financing mechanisms to make renewables economically viable.
By freeing tropical islands from the burden of imported fossil fuels, investments in ocean energy can provide long-term economic benefits and contribute to a sustainable future.
The Power of Ocean Energy .

Ocean energy, with its predictability and stability, offers a powerful solution for islands seeking constant power supply.
Unlike solar and wind energy, which are variable and intermittent, ocean energy, particularly wave energy, provides a reliable source of power.
Additionally, wave energy has multiple applications, including running hydroelectric plants, desalinating water, and supporting smaller systems like fisheries.
European wave energy company Seabased has developed technology that works even in moderate wave climates, making it a viable option for many islands.
Considerations for the Environment .
Ocean energy technology, such as Seabased’s buoys, are designed to minimize visual impact, ensuring that the natural beauty of islands is preserved.
Furthermore, these wave parks can serve as artificial reefs, promoting biodiversity and creating additional fishing opportunities.
The integration of renewable energy solutions not only benefits the environment but also attracts ecotourists who prefer to stay in sustainable destinations.
By embracing renewables, islands can tap into the growing market of eco-conscious travelers, boosting their economies and promoting a greener future.
Investment in Renewable Energy .

Investment in renewable energy for island development is on the rise.
Small Island Developing States (SIDS) have realized the economic and environmental benefits of shifting to renewable energy sources.
Research shows that SIDS could save billions annually by switching to 100% renewable sources.
Initiatives like the Global Island Partnership and the Clean Energy for EU Islands program aim to support islands in their energy transition.
Investments in wave energy and other renewable technologies are increasing, paving the way for a future free from fossil fuels.
Conclusion .
Energy from the ocean has the potential to liberate tropical islands from the shackles of fossil fuels.
Ocean Thermal Energy Conversion (OTEC) is a promising approach that uses the vast amounts of energy of the ocean to generate renewable electricity and potable water.
By embracing ocean energy, islands can reduce energy costs, achieve energy security, and contribute to a sustainable future.
With the right investments, regulations, and public support, tropical islands can become pioneers in the global shift towards clean and renewable energy sources.
Embracing the power of the ocean is not only a practical choice but also a step towards preserving the natural beauty and resources that these islands hold dear.
