Dubai has built the world’s largest solar-powered desalination plant in Hatta, providing clean drinking water to 2 million people daily. Unlike traditional plants that rely on fossil fuels, this facility uses solar energy and reverse osmosis for a zero-emission process. This is vital for desert regions like the Middle East, where freshwater is scarce. Dubai’s approach shows solar energy can address water shortages sustainably and may serve as a model for future global water security, in particular the Middle Easter Countries.
