The ongoing transition from coal to natural gas and renewables in the U.S. electricity sector is dramatically reducing the industry’s water use, a new Duke University study finds.

“While most attention has been focused on the climate and air quality benefits of switching from coal, this new study shows that the transition to natural gas – and even more so, to renewable energy sources – has resulted in … [more…]

Leading Water Utilities Reducing Water-Energy Nexus Pressures

Leading Water Utilities Reducing Water-Energy Nexus Pressures

Water is required to produce nearly all forms of energy. At the same time, electricity is needed to provide drinking water and treat wastewater. Recognizing rising water-energy nexus pressures, a range of water utilities around the world are developing innovative solutions to reduce these pressures.

Intensification of the water footprint of hydraulic fracturing

Map of water stress and shale plays; hydraulic fracturing

Abstract

Unconventional oil and gas exploration in the United States has experienced a period of rapid growth, followed by several years of limited production due to falling and low natural gas and oil prices. Throughout this transition, the water use for hydraulic fracturing and wastewater production in major shale gas and oil production regions has increased; from 2011 to 2016, the water use per well increased up to 770%, while … [more…]

You probably have no idea how much water is needed to produce electricity

Photo: That’s not carbon dioxide. It’s steam.

You’re likely within a few feet of an electric switch. When you turn it on, some power plant many miles away starts producing the electrons your device needs. Despite the growth of renewable-energy solutions, most of those electrons are still generated by fossil fuel or radioactive fuel.

The trouble is that thermal electricity generation—a category that includes coal, natural gas, and nuclear power—doesn’t

Sourcing renewable energy such as hydropower from aspects of ordinary life like drinking water is an innovative, fresh, and wonderful concept. And this is being done in Portland, which is the biggest city in the US state of Oregon as well as the seat of the Multnomah County. It is a big port in the Willamette Valley region in the Pacific Northwest. Portland, USA, now produces electricity from turbines which … [more…]
