An international research team has proposed to use nighttime radiative cooling to harvest water from PV panels and reuse it for module cleaning during the daytime. According to their findings, the proposed system has, also, a beneficial effect on the modules’ operating temperature.
When looking from the right vantage point towards Mission Trails Regional Park, a brown hill can be seen. This is the San Diego County Water Authority’s Mission Trails Flow Regulatory Structure II Project, or FRS II, under construction. Once complete, the dirt hill will be leveled to its previous contours and revegetated with native plants – many seeded from plants within the park itself.
It’s possible that San Diego County won’t receive significant rainfall during December, which would significantly elevate the wildfire danger throughout the region, according to the National Weather Service.
“The storms that have been forming off the Pacific Northwest are not dropping into Southern California,” said Dan Gregorio, a weather service forecaster.
San Diego is participating in a statewide program to monitor its untreated wastewater for the virus that causes COVID-19, it was announced Tuesday. City staff have been monitoring for severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2, in untreated wastewater at the Point Loma Wastewater Treatment Plant this month. Following the test run, staff will monitor for SARS-CoV-2 three times a week from January through June 2021.
It’s not just Californians paying attention to the state’s water supply anymore. It’s Wall Street.
In a sign of the growing value of water in a warming world, investors began trading futures of the coveted commodity, tied to California water prices, for the first time last week.
The novel marketplace allows speculators to make money betting on future prices of California water while allowing farmers, businesses and municipal suppliers to hedge against price swings and stabilize their costs.
Rising seas can evoke images of waves crashing into beachfront property or a torrent of water rolling through downtown streets. But there’s a lesser-known hazard of climate change for those who live along shorelines the world over: freshwater in the ground beneath them creeping slowly upward. For many Bay Area residents who live near the water’s edge, little-publicized research indicates the problem could start to manifest in 10-15 years, particularly in low-lying communities like those in Oakland, Alameda and Marin City.

In what was hailed as a “landmark agreement,” farmers in an area of southern Tulare County blamed for sinking the Friant-Kern Canal from excessive groundwater pumping will chip in a hefty amount to help pay for a fix.
How hefty could be decided by their payment choice.
A longer term payment option would be $200 million.
Pure Water Oceanside is installing new pipelines and drilling wells as the recycled water project continues on track for completion in 2022. The advanced water purification project, and expansion of the City of Oceanside’s existing recycled water system, will deliver a new, local source of high-quality drinking water supplying more than 30% of the city’s water supply when completed.
Amid long-term forecasts indicating California could be headed into another dry winter, discussions at the California Farm Bureau Annual Meeting focused on current and future water policy and the challenges facing short- and long-term supplies.
During a breakout session as part of the virtual Annual Meeting, Ernest Conant, U.S. Bureau of Reclamation regional director for the California-Great Basin Region, described how regulatory constraints have affected water allocations from the federal Central Valley Project.
