Solar and wind energy preserve groundwater for drought, agriculture

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…]

A Water-Smart Future Is Just Around the Block

A Water-Smart Future Is Just Around the Block

Many locations around the world are implementing inspirational projects to encourage the wise use of water while enhancing resilience to climate change and ensuring resource efficiency.

Harvesting stormwater runoff

The City of Santa Monica’s Los Amigos Park Storm Water Harvesting and Direct Use Demonstration Project involves capturing stormwater runoff from a storm drain near the park, pre-treating flows with a hydrodynamic separator, storing flows in a subsurface storage system, and … [more…]

Device that works like a lung makes clean fuel from water

A device inspired by human lungs can split water into oxygen and hydrogen – Agencja Fotograficzna Caro / Alamy By Chelsea Whyte

Human lungs move gas through a thin membrane, extracting oxygen and sending it into our blood stream. Now a device uses the same principle to power the reactions used for making hydrogen fuel.

Yi Cui at Stanford University and his colleagues set out to mimic human lungs to … [more…]

Another Benefit of Renewable Energy: It Uses Practically No Water Compared to Fossil Fuels

The Energy Information Administration (EIA) recently highlighted a little-discussed benefit of using renewables like wind and solar to produce electricity: Unlike most power sources, they require “almost no water.”

This is remarkable because thermoelectric power generation is the leading use of water in America. (That said, only three percent of power generation’s 133 billion gallons a day of water is considered “consumptive use,” as the U.S. Geological Survey says, “meaning … [more…]

Did You Know Reducing Your Energy Use Conserves Water?

DID YOU KNOW REDUCING YOUR ENERGY USE CONSERVES WATER?

Water is one of the most important utilities in our lives, which is why ensuring our ability to use it is so important. Unfortunately, we often end up wasting more than just water when we leave the tap running for too long.

In fact, more than a quarter of all the energy we use revolves around heating and using water, and that’s just for normal day-to-day activities like washing dishes.
