The Southwest of the U.S. is dealing with a multi-year drought. Many man-made drinking water reservoirs are at all-time lows, and they continue to deplete as vast quantities of water are lost to evaporation. What if the same scorching sun that causes so much of this water loss were harnessed for electric power? Countries like Japan and Brazil have been deploying floating solar arrays. “Floatovoltaics” can reduce evaporation in dry climates by as much as 90 percent. So, covering drinking water reservoirs with solar panels could result in significant water savings while producing significant amounts of clean energy at the same time.
