Renewable Energy Systems
Private islands are increasingly turning to renewable energy to break free from the financial burden of fossil fuel imports. For some nations, these imports can consume as much as 20% of their GDP. Let’s dive into how hybrid solar and wind systems are helping islands maintain reliable energy supplies.
Solar and Wind Power Setup
Blending solar panels with wind turbines in hybrid systems is proving to be a reliable way to generate energy, even under changing weather conditions. A great example is Sint Eustatius, where a hybrid power plant expanded its solar capacity from 1.89 MW to 4.15 MW, supported by a 5.9 MWh battery storage system. This setup is robust enough to meet peak energy demands.
Another success story comes from Denmark’s Samsø Island. By 2017, the island had adopted nearly every renewable energy technology available. This included biogas plants, wood and straw heating systems, a large solar heat plant spanning 27,000 square feet, and a mix of onshore and offshore wind turbines with a total capacity of 34 MW. The result? The island now generates more energy than it consumes.
The financial advantages of renewable energy are just as compelling. In the Maldives, imported diesel costs range from 30 to 40 cents per kilowatt-hour, significantly higher than the 5 to 7 cents per kilowatt-hour seen in nearby South Asian nations. However, a solar project supported by the World Bank has brought the cost of electricity in the Maldives down to just 9.82 cents per kilowatt-hour, making it one of the most cost-effective rates among small island nations.
"Solar has cut my business expenses by 35 percent, allowing me to expand operations. The primary motivation to go solar was cost savings, but I am pleased to know that I am doing my part to alleviate climate change considering its impact on islands such as Jamaica."
– Shelly-Ann Dinnall, third-generation chicken farmer
Energy Storage Systems
Energy storage systems, particularly batteries, are essential for managing the fluctuations in power generation from renewable sources. They stabilize energy frequency, provide backup during peak demand, and reduce reliance on diesel generators. Modern battery storage solutions are highly responsive and offer ample capacity.
Proper planning is key to maximizing these systems. Resorts and other operators should perform energy audits to assess peak and average consumption, evaluate solar energy potential based on local conditions, and determine how long operations need to function without sunlight. This data is crucial for sizing battery systems effectively. Lithium-ion batteries are a popular choice due to their efficiency, high energy density, and long lifespan. These batteries can be charged through solar panels, diesel generators, or the grid, creating opportunities for cost savings through energy arbitrage.
In addition to storage advancements, incorporating energy-saving measures enhances the overall efficiency of these systems.
Energy Efficiency Methods
Efficiency isn’t just about generating and storing energy – it’s also about using it wisely. Combining energy efficiency with renewable energy reduces the size and cost of installations. A case in point: Fiji managed to save approximately 9.3 GWh of electricity in a single year by implementing appliance labeling and Minimum Energy Performance Standards.
Smart automation systems are particularly useful in resort settings. These systems adjust lighting, heating, cooling, and refrigeration based on occupancy, eliminating the need to run at full capacity when it’s not necessary. Building design also plays a role – strategic placement of solar panels, natural ventilation, and energy-efficient lighting can significantly lower energy consumption.
The benefits aren’t just environmental. Wind energy, for example, offers a staggering 1,164% return on its initial energy investment while offsetting CO₂ emissions equivalent to those produced by nearly 42 million cars in 2019. Forward-thinking projects like VPP4ISLANDS are taking it a step further by using virtual energy storage, digital twin technology, and distributed ledgers to create intelligent energy networks that optimize power distribution across islands.
Waste Management Systems
Private islands face distinct challenges in handling waste. Without municipal waste collection or centralized treatment facilities, these remote locations must adopt tailored strategies to minimize their environmental footprint while maintaining efficient operations. One effective approach is to create closed-loop systems that transform waste into usable resources, promoting self-reliance. These systems exemplify how luxury living can coexist with environmentally-conscious practices. Let’s dive into how zero-waste initiatives are reshaping waste management on private islands.
Zero-Waste Programs
Zero-waste programs on private islands aim to reduce landfill use by prioritizing composting, recycling, and advanced biological treatment methods. Composting is often the cornerstone of these efforts. Organic waste – whether from kitchens, landscaping, or guest areas – is converted into nutrient-rich soil amendments, cutting the need for imported fertilizers.
Recycling efforts go beyond simply separating materials. Crushed glass, for example, can be used in construction, metals are sent off-site for reprocessing, and shredded paper or cardboard can serve as garden mulch. Proper sorting and thorough staff training are key to maximizing recycling efficiency.
Some islands take innovation a step further with worm-based septic systems. These systems use earthworms to break down organic waste and sewage, producing clean water and compost as byproducts. A resort highlighted by GRIFFCOMM exemplifies this approach, with a system that recycles nearly everything and even uses treated sewage to grow vegetables. The resort also funds research through a registered charity to advance these sustainable practices.
Beyond waste management, islands also look to rainwater harvesting to address water scarcity.
Rainwater Collection and Filtration
Given their limited access to freshwater, rainwater harvesting is a vital sustainability measure for private islands. These systems collect, store, and purify rainwater for drinking, irrigation, and other operational needs. For instance, just one inch of rainfall on a 2,500-square-foot surface can yield about 1,500 gallons of water, showcasing how even small structures can gather significant amounts during a storm.
To ensure water quality, rooftops, gutters, and downspouts must remain clean, while first flush diverters capture debris and contaminants from initial runoff. Storage tanks should be made from food-grade, UV-resistant materials to prevent chemical leaching and algae growth. Sealed tanks also help avoid mosquito breeding while maintaining proper ventilation. Experts recommend a minimum storage capacity of 5,000 gallons for domestic use. In practice, residents in the U.S. Virgin Islands using rainwater cisterns manage with an average of just 24 gallons per person per day.
Filtration and disinfection are equally important. Multi-stage filters remove sediments and pathogens, while UV light systems kill microbes without leaving chemical residues. Chlorination can provide additional protection, and regular water testing ensures the water remains safe.
Barbados offers a compelling example of rainwater harvesting in action. Rooftop collection systems there supply water for irrigation, household use, and groundwater replenishment. This approach is especially valuable during droughts in the Caribbean, where roughly 10 million residents face water scarcity.
On-Site Wastewater Treatment
For islands without access to municipal sewage systems, on-site wastewater treatment is essential. These systems not only protect groundwater from contamination but also allow treated water to be reused for landscaping and maintenance, reducing the demand for precious freshwater.
The choice of wastewater treatment system depends on the property’s size and local regulations. Smaller properties often use septic tanks, which cost between $3,000 and $7,000. Larger properties may opt for aerated wastewater treatment systems, priced at $8,000 to $15,000, or custom multi-stage solutions, which can range from $20,000 to $120,000.
Reusing treated wastewater for irrigation – whether for landscaping, golf courses, or agricultural areas – significantly reduces freshwater consumption. For example, the Seven Seas Water Group’s installation at Sandals Emerald Bay in the Bahamas processes all resort sewage, providing enough treated water for on-site needs and even surplus capacity for the local community.
To keep these systems running smoothly, regular inspections, pump-outs, and timely replacements are necessary. Using biodegradable cleaning products helps maintain the delicate bacterial balance within the system. Service packages that include routine maintenance can prevent costly emergency repairs down the line.
Green Architecture and Design
Building sustainably on islands requires careful planning to reduce transport emissions and ensure structures can handle tough marine environments. The isolation of these locations means every construction choice matters – materials must be shipped across water, and buildings need to endure the elements. Smart design not only lowers a property’s carbon footprint but also creates spaces that blend seamlessly with their natural surroundings. Let’s dive into how sourcing materials, utilizing natural ventilation, and building resilient structures come together to shape eco-friendly island architecture.
Local and Renewable Building Materials
Choosing materials from the island itself or nearby areas helps reduce emissions and supports local communities. For example, The Residences at Secret Bay in Dominica use locally sourced stone, wood, and bamboo, promoting sustainable practices in the region. Similarly, Laucala Island in Fiji incorporates traditional materials like thatched roofs made from sago palms, doga timber, and magi magi – a coconut husk weave. Bamboo, a standout option, is highly renewable since it can be harvested without harming the plant. Other traditional materials like thatch, clay, and coconut husk have proven their durability over centuries.
Some islands take sustainability even further. Nikoi Private Island repurposes driftwood collected from beaches and employs local teams for construction. On Isla Palenque in Panama, materials like thatched roofs and wood furniture are crafted from fallen trees in an on-island workshop.
"A big part of the sustainable design is seen in the use of local materials like the thatched roofs and the wood furniture, sourced from fallen wood and crafted at our workshop on the island."
- Hans Pfister, Cayuga Collection
For islands lacking abundant local resources, sustainable sourcing becomes crucial. Kudadoo Maldives Private Island, for instance, imports wood from Canada, New Zealand, and Indonesia, ensuring all materials come from responsibly managed forests.
Natural Cooling and Ventilation
Energy-efficient designs go beyond materials – natural cooling strategies are key to reducing energy demands. Island climates, with their steady ocean breezes and warm temperatures, offer perfect conditions for natural ventilation. By tapping into these natural elements, architects can minimize reliance on energy-intensive air conditioning. Nikoi Island, for instance, uses a double-layered roof design that encourages airflow, along with overhead fans and beach houses positioned close to the shoreline.
"Ocean breezes and the unique cooling effect of the landmass provide an example of ‘nature’s air-con’, providing ‘simple barefoot luxury’ in a sublime setting."
- Nikoi Island
At Kudadoo Maldives, carefully placed windows enhance cross ventilation, cutting down on cooling needs. Isla Palenque combines several strategies, including cross ventilation, solar-powered showers, and optimal use of natural light, to lower energy consumption. Thoughtful building orientation and shading techniques further reduce energy use by maximizing natural light during cooler times and minimizing heat during hotter periods. Outdoor decks with overhangs, umbrellas, and canopies provide shaded spaces for much of the day, adding comfort while reducing heat exposure.
Green spaces and water features also play a big role in cooling. Studies show that features like reflective roofs, water bodies, and greenery can cool urban areas by 0.5°C and lower indoor temperatures by 3–5°C, while delivering substantial long-term benefits.
Elevated and Weather-Resistant Structures
Private islands face unique risks from extreme weather, making resilient construction a necessity to protect both people and ecosystems. Storms and flooding are major threats, and elevated structures can safeguard buildings while minimizing harm to fragile habitats. The financial benefits of weather-resistant designs are clear: every dollar spent on resilience saves four dollars in repair costs, and climate adaptation over the next decade could generate $7.1 trillion in net benefits by 2030.
The importance of resilient construction became evident in Saint Lucia in 2010, when Hurricane Tomas caused catastrophic damage, wiping out 43% of the country’s GDP overnight and destroying infrastructure like power lines and roads. To mitigate such risks, hurricane-resistant features – such as reinforced concrete, impact-resistant windows, and elevated foundations – are essential. These designs not only protect against disasters but also maintain aesthetic appeal.
"You need to prepare to be surprised."
- Associate director at ARUP
Traditional materials, when properly treated, can also enhance resilience. Local timber, reinforced bamboo, and well-constructed thatched roofs have withstood tropical storms for generations. Combining traditional building knowledge with modern engineering creates structures that are tough, sustainable, and ready for whatever nature throws their way.

Food and Resource Practices
Private islands are creating self-sufficient food systems that not only serve their guests but also support local communities. By focusing on on-site organic farming, forming partnerships with nearby communities, and offering educational programs, these destinations are reshaping the way luxury properties approach food and sustainability. Let’s dive into how these efforts are making a difference.
On-Site Organic Farming
Many private islands are establishing organic farms to grow fresh produce while promoting biodiversity. These farms are designed to operate sustainably, relying on practices that reduce the need for external inputs and prioritize soil health. For example, soil testing is a key step, with farms aiming for 3% organic matter – a challenging goal on sandy island soils.
Crop rotation plays a big role in maintaining soil quality. By waiting up to eight years before replanting the same vegetable family, farms improve soil structure and biodiversity. Additionally, cover crops and complex rotations are used to minimize soil disturbance, while certified organic seeds and seedlings are sourced whenever possible.
Organic fertilizers are another critical element. These fertilizers, made from animal, plant, or mineral sources, are carefully vetted with organic certifiers to ensure they align with sustainable farming standards. To manage pests naturally, farms adopt Integrated Pest Management (IPM) strategies, which reduce reliance on conventional chemical inputs.
As noted by Sustainable Agriculture at UGA:
"Organic production is not simply the avoidance of conventional chemical inputs, but rather is a way of production that focuses on preventative practices that limit the need for external and off‐farm inputs, often called cultural practices."
Buffer zones are also established around farm areas to prevent contamination from surrounding land, ensuring the purity of organic production systems.
Local Community Partnerships
Collaborations with local communities are another cornerstone of sustainable practices. These partnerships provide fresh ingredients for the islands while boosting the local economy. By aligning with community needs, these initiatives ensure that tourism benefits local residents rather than displacing them.
For example, islands establish agreements with local fishermen, farmers, and food producers to supply fresh ingredients. This not only reduces the reliance on imported goods but also supports steady incomes for local workers. The result? Healthier food options for both guests and the community.
Education is another key component of these partnerships. Islands work with local tourism professionals and community members to teach them about sustainability practices, empowering them to take an active role in preserving their environment. Through ongoing consultations, communities also participate in conservation efforts that balance ecological and social goals.
One notable example is the Pacific Organic and Ethical Trade Community (POETCom), which has been promoting sustainable agriculture across island communities since its founding in 2012. Their Strategic Plan for 2013–2017 emphasized production, environmental stewardship, value chains, and sustainability, supported by bi-annual technical exchanges and shared resources.
Guest Education Programs
Private islands are also turning guest visits into opportunities to learn about sustainability and biodiversity. Banwa Private Island, for instance, partnered with the Aquos Foundation to create the "Biodiversity in Full Color" exhibition. This initiative combined art and education, featuring works by artist Samantha Kaspar, whose paintings of local wildlife aimed to inspire guests to appreciate and protect the environment.
"Our approach to conservation is holistic. By combining art, education, and community engagement, we aim to inspire positive change. We believe that by working collaboratively with local communities, we can achieve sustainable solutions that benefit both people and the planet. Our partnership with Samantha exemplifies this approach, as her art serves as a powerful tool for raising awareness and cultivating a sense of stewardship." – Janet Oquendo, Island Manager, Banwa Private Island
These educational efforts go beyond the guest experience. The Aquos Foundation also introduced "Mga Hero ng Planetang Blue", a book designed to inspire environmental responsibility among local students. By reaching younger generations, these programs create a ripple effect that extends far beyond the duration of a guest’s stay.
