Tag: water-energy nexus

The water-energy nexus is the relationship between how much water is evaporated to generate and transmit energy, and how much energy it takes to collect, clean, move, store, and dispose of water.

Reuse: Global Reach, Local Impact

In just 14 years, the United Nations estimates the world will only have 60% of the water resources it needs, if we do nothing different. Obvious solutions to water scarcity can include water reuse, wastewater reclamation, and conservation. But, what if we are just hitting the tip of the iceberg

Energy in Every Droplet

Energy in Every Droplet

The intersection of water and energy is an interface that in the water industry we often explore in terms of operational efficiencies, conservation policies, and cost perspectives. But on a micro scale, the water-energy nexus is encapsulated within a single molecule. And the research surrounding the separation of this molecule’s

Energy Impetus: What Will Drive Wastewater Energy Recovery?

Energy Impetus: What Will Drive Wastewater Energy Recovery?

Humans have been harnessing water’s energy for thousands of years. Archaeologists have discovered trip hammers powered by a water wheel—dating back to 202 BC and 9 AD—that were used to grind grain, break ore, and press paper in early China.

Today, we continue to rely on water to generate energy. Modern

Water Reuse and Sustainability Attract Industries

Water Reuse and Sustainability Attract Industries

Writing in its 2012 “Guidelines for Water Reuse,” EPA acknowledges that “energy efficiency and sustainability are key drivers of water reuse which is why water reuse is so integral to sustainable water management.” Furthermore, “the water-energy nexus recognizes that water and energy are mutually dependent.”

Water & Energy: A Crucial Conversation

Water & Energy: A Crucial Conversation

Allan Hoffman knows why so many municipalities consume far too much energy when moving drinking water through their systems: water people and energy people simply don’t spend enough time talking to one another. And this is a problem that Hoffman, a visiting professor of renewable energy and desalination at the

The Water-Energy Nexus

In this study, water and energy use data (2006–2011) from water wells are analyzed for San Jose State University (SJSU). SJSU is a four-year public university with an enrollment of 30,000 and located in San Jose, CA. It is found out that water and energy use correlate each other, and

Irrigation Demand Management

For many, a supply side approach is not much of an option. Rather, they are instituting demand side reduction programs–and in such sectors as agriculture, demand response programs–in an effort to achieve water efficiencies. “I believe that the water crisis that’s unfolding before us–faster in some areas than others–will be
