Floating solar farms, a cutting-edge fusion of renewable energy and innovative use of space, are gaining traction globally. These installations, set on bodies of water, not only conserve valuable land but also benefit from the cooling effects of water, enhancing their efficiency. As part of the broader expansion in renewable energy, by 2025, solar capacity worldwide is anticipated to reach around 2.3 terawatts. While this figure is just a fraction of the estimated 432 terawatts needed to meet all of Earth’s electricity demands, it represents significant progress in the right direction. Here, we delve into the five largest floating solar farms around the world, shedding light on their capacities, locations, and the technological advancements they bring to the table, each contributing to this growing total of global solar capacity.
