Joe Seaman-Graves is the city planner for the small town of Cohoes, New York. He was in search of a less costly way of providing electricity to the town. There was no extra land to build on. But Cohoes does have a nearly 6-hectare water reservoir. Seaman-Graves looked up the term “floating solar” on Google. He was not familiar with the technology, which has long been a popular way to produce clean energy in Asia. Seaman-Graves learned that the town’s water reservoir could hold enough solar panels to power all city buildings. And that would save the city more than $500,000 each year. Floating solar panel projects have seen quick growth as a new form of clean energy in the United States and Asia. Floating solar panes are sought after not just for their clean power, but also because they save water by preventing evaporation.
