Canal-top solar solution

Climate change is exacerbating water scarcity in many parts of the world, and while renewable energy is a long-term solution, in many cases it is a short-term solution, too. One such case in the energy-water nexus is that of canal-top solar, which was pioneered in India a decade ago, when the first canal-top solar array was installed in Gujarat. And new findings from the University of California and the resulting Project Nexus are now shining attention on a symbiotic application: saving water, while generating solar energy, without occupying arable land.
