Solar and wind energy preserve groundwater for drought, agriculture

Using drought-prone California as a case study, a research team shows that increased solar and wind energy can reduce the reliance on hydropower, especially during drought. Credit: Egan Jimenez, Princeton University

Solar and wind farms are popping up around the country to lower carbon emissions, and these renewables also have another important effect: keeping more water in the ground.

A new Princeton University-led study in Nature Communications is among the … [more…]

Water utilities nationwide are grappling with aging infrastructure, environmental degradation and climate change.

Existing water systems are also highly centralized and supported by old-fashioned financing models. But what if instead of simply replacing the physical infrastructure and financing mechanisms, the sector reinvented them?

That was the approach California took … [more…]

Share the Wealth: A Cap-And-Trade System of Water Conservation and Resiliency?

California has struggled with drought for most of the last decade. From 2011–2015, the state experienced the driest four-year stretch in recorded history, leading to unprecedented water restrictions for residents, including a state mandate to reduce water use by 25 percent.

Heavy precipitation last winter relieved much of California, but dry conditions linger. Wildfires raged during the fall and early winter months, ravaging towns and hillsides from Los Angeles to … [more…]
