Bioenergy is frequently considered one of the options to reduce greenhouse gases for achieving the Paris climate goals, especially if combined with capturing the CO2 from biomass power plants and storing it underground. To avoid a substantial increase in water scarcity, biomass plantations for energy production need sustainable water management, a new study shows.

Two cybersecurity researchers have published a new book to help train employees at public utilities to recognize cybersecurity vulnerabilities and develop measures to defend their networks from increasingly sophisticated cyberattacks.

DARPA recently awarded five contracts and selected one government partner to develop technology to capture potable water from the air in quantities sufficient to meet critical DoD needs, even in extremely dry climates. The Atmospheric Water Extraction (AWE) performers aim to meet clean water needs of deployed troops, even in austere environments.

River systems are essential resources for everything from drinking water supply to power generation – but these systems are also hydrologically complex, and it is not always clear how water flow data from various monitoring points relates to any specific piece of infrastructure. A new tool that draws from multiple databases to give water resource managers and infrastructure users the information they need to make informed decisions about water use on river networks.

A recent study showed that targeted efforts to increase water efficiency could save enough water annually to fill Lake Mead. It could happen without significantly compromising economic production, jobs or tax revenue.

In low precipitation periods – where and how is the limited available water distributed and what possibilities are there for improving retention in the soil and the landscape?

Groundwater makes up 30 to 50 percent of California’s water supply, but until recently there were few restrictions placed on its retrieval. Then in 2014 California became the last Western state to require regulation of its groundwater, and water managers in the state’s premier agricultural region – the state’s Central Valley – are tasked with estimating available groundwater. It’s a daunting technological challenge – but scientists can help by pairing satellite data with high-resolution monitoring to estimate groundwater depletion.

The prevailing wisdom for wave energy capture has been to construct a large installation offshore, a few kilometers in the middle of the sea. But, says one expert, that’s expensive and unreliable. Offshore waves can reach tsunami-like heights that can pulverize the equipment, so few insurance companies have been willing to cover these kinds of installations and, if they do, it’s at a high cost. There is a less expensive, safer alternative: Installing “floaters” on existing manmade structures – piers, jetties and breakwaters – and putting the main energy-creating equipment with its sensitive computers and generators on land.

Reusing low-saline oilfield water mixed with surface water to irrigate farms in the Cawelo Water District of California does not pose major health risks, as some opponents of the practice have feared, a new study finds.
