Climate idea

Installing solar panels over California’s canals could yield water, land, air and climate payoffs

Climate change and water scarcity are front and center in the western U.S. The region’s climate is warming, a severe multi-year drought is underway and groundwater supplies are being overpumped in many locations.
Western states are pursuing many strategies to adapt to these stresses and prepare for the future. These include measures to promote renewable energy development, conserve water, and manage natural and working lands more sustainably.
As engineers working on climate-smart solutions, we’ve found an easy win-win for both water and climate in California with what we call the “solar canal solution.” About 4,000 miles of canals transport water to some 35 million Californians and 5.7 million acres of farmland across the state. Covering these canals with solar panels would reduce evaporation of precious water – one of California’s most critical resources – and help meet the state’s renewable energy goals, while also saving money.

        By covering canals with solar panels, we can conserve water, generate renewable energy, and protect our environment.. a great idea ... if it has no negative effects on the life in it of course :)
