If L.A. is going to stop burning fossil fuels by 2045 a key goal of Mayor Eric Garcetti’s proposed Green New Deal it must store a lot more of the excess solar and wind energy it produces during the day so it doesn’t have to rely on gas and coal energy to power the city when the sun sets and the wind dies. There’s a growing focus on building big batteries — for example, the kind that use lithium ions. But L.A. needs energy storage that is far bigger than any traditional battery.
The company that built and operates the Carlsbad seawater desalination plant took over stewardship of the Agua Hedionda Lagoon this week, the only San Diego County lagoon that allows power boats, kayaks, paddleboards and other recreational and commercial activities. Poseidon Water will be responsible for dredging Agua Hedionda to keep it open and deep enough for public and private uses including a YMCA Aquatic Park, the Hubbs-SeaWorld Fish Hatchery, the Carlsbad Aquafarm shellfish operation and the lagoon foundation’s nature center.
