As the global paradigm shifts towards embracing sustainable practices and renewable energy sources, Cambodia has mirrored this transformative trajectory in recent years. Solar energy is projected to emerge as the preeminent renewable energy source for the country, closely followed by hydroelectricity. After a comprehensive examination of various renewable energy options, solar energy stands out as having the highest potential for KRS. Capitalizing on this opportunity, strategically positioned solar infrastructures will be implemented to power the island, representing a significant step towards a cleaner and more sustainable energy future.

To establish the most efficient and sustainable energy system for KRS, solar energy will take the forefront as the primary source of power generation. This involves a synergistic approach encompassing utility-scale solar farms and residential rooftop solar panels, forming a robust network capable of meeting the diverse energy needs of commercial, industrial, and domestic sectors. Despite potential reductions in solar irradiation during the rainy season, the overall annual electricity generation remains sufficient, justifying the investment in solar infrastructure. Additionally, the incorporation of solar-powered charging stations aims to encourage the adoption of Electric Vehicles among locals. While recognizing the importance of more traditional power generation methods such as biomass and fossil fuel energy, these will serve as complementary sources to fulfill any remaining energy requirements, ensuring a balanced and resilient energy landscape for KRS.

The tropical climate shaped by KRS's geographical location presents a significant opportunity for rainwater harvesting, serving as a valuable water source and bolstering green energy practices on the island. This harvested rainwater holds potential applications for irrigation and can undergo treatment to meet municipal water needs. KRS's water supply will predominantly be sourced from rainfall and surface water, supplemented by some aquifer groundwater. To fulfill domestic water demands, rooftop water catchment infrastructure will be strategically implemented, ensuring an efficient collection system.

Moreover, the island's commitment extends from water source to proper water management. Treated wastewater will be repurposed for agricultural needs, creating a closed-loop system that minimizes water consumption. The integration of natural water treatment methods will involve filtration, disinfection, and utilizing carbon emissions to nourish microorganisms responsible for sewage treatment. This environmentally conscious approach not only promotes water conservation but also aligns with broader initiatives, such as biomass energy production derived from the waste generated in the treatment process. Thus, KRS aims to harness its tropical climate advantage to establish a resilient and eco-friendly water supply system that aligns with its commitment to sustainable living practices.
