California to Erect Solar Panels over Canal to Save Water from Evaporation

 

Some scientists and engineers believe that covering California’s irrigation canals saves it from drought and that they could meet the state’s renewable energy commitment.

Vocabulary

Some scientists and engineers believe that covering California’s irrigation canals saves it from drought and that they could meet the state’s renewable energy commitment.

 

Project nexus, a concept and pilot project in Turlock Irrigation District, will cover a mile-long stretch of canal in five megawatts worth of solar panels. It will hopefully increase renewable power generation, water improvements, reduced vegetative growth in the canals, and reduced water evaporation. The panels could prevent 65 billion gallons of freshwater loss through evaporation.

 

This concept, as reported in 2021 by GNN, has already proven to work in the Indian state of Guajarat, where the cooler temperature of the moisture beneath the panels cooled them down, resulting in a small but significant increase in power generation.

 

Roger Bales, part of the UC Merced paper, argued recently in the Smithsonian Magazine that covering the thousands of miles of California canals with panels would generate 13 gigawatts of renewable energy capacity: half of what the state would need to entirely decarbonize by its self-imposed 2045 deadline.

“California grows food for an ever-increasing global population and produces more than 50 percent of the fruits, nuts, and vegetables that U.S. consumers eat,” writes Bales. “Building these [canal] solar arrays could prevent more than 80,000 acres of farmland or natural habitat from being converted for solar farms.”

Making sense on all levels, Project Nexus is tremendously exciting, and Bales explains that other similar projects are in the making.
