California Utility Set to Test Whether Covering Canals With Solar Panels Can Save Water

A California utility is set to test out whether covering canals with solar panels can save water by preventing evaporation, among other benefits.

Project Nexus is being run on a small stretch of canals operated by the Turlock Irrigation District in central California. The idea is based on an academic paper, which suggested doing this could also generate solar energy on land that wouldn’t have to be disturbed.
