Energy Newsbriefs Blog

This current awareness service is prepared by the WSU Energy Program Library with funding from the U.S. Department of Energy State Energy Program. This information is provided for energy professionals and interested members of the public to highlight recent energy-related news, articles, and reports that discuss energy efficiency, energy conservation, and renewable sources of energy in engineering and policy circles.

Conserving, Tracking Commercial Buildings’ Water Use

Consulting-Specifying Engineer, July 2015, by Mark Graf.

"The immediate interest in a building’s energy efficiency typically focuses on heating and cooling systems, and with conserving nonrenewable resources like power and gas. Throughout the world, however, there is increased pressure to track and conserve water in nonresidential buildings."

Energy Trust [OR] Lends a Hand with Irrigation Efficiency

Capital Press, Feb. 9, 2015, by Lacey Jarrell.

"More consistent water application [using variable frequency drives] can mean greater water and power savings for large- or small-scale farmers."

Watts in a Drop of Water: Savings at the Water-Energy Nexus

ACEEE White Paper, Nov. 5, 2014, by Rachel Young. [Free registration required to view full-text.]
http://aceee.org/white-paper/watts-in-drop-water

"This paper shows a range of energy intensities for water and wastewater services and in residential hot and cold water. We draw from existing data to develop national estimates of energy savings associated with water savings, including energy used in water conveyance, water heating, and water and sewage treatment."

Evaluating Air Compressor Cooling Systems

Compressed Air Best Practices, Aug. 2014, by Nitin G. Shanbhag.

"As the population continues to grow in the United States, industrial water use will need to continue to fall to help offset the increases in public-supply water use. Water-cooled compressed air systems provide an opportunity for sustainability managers to reduce associated cooling water consumption and costs. If switching to air-cooled air compressors is not possible, understanding the costs and the alternative types of liquid cooling systems is important."

Efficient Building Water Use

Consulting-Specifying Engineer, July 2014, by Willa Kuh and Fred Betz.
http://www.csemag.com/single-article/efficient-building-water-use/5c43e78511f4c18036dd0e018167ce82.html

"The escalating cost of providing potable water in the United States is creating new urgency for owners of commercial, industrial, and institutional buildings to respond with greater engineered water efficiency."

Banking Water for Power

Public Power, Jul/Aug 2014, by Alice Clamp.

"Public utilities often provide water service to their customers as well as electrical service. And many of them have noteworthy water conservation programs to manage cyclical variations in supply. Utilities are also banking and recycling water used in power plants to realize greater operational efficiencies."

Greening the Strip [Las Vegas]

EcoBuilding Pulse, Apr. 30, 2014, by Hallie Busti & Annie Milewski.

"The sea of resorts, shopping centers, and convention halls located just outside Las Vegas’ city limits may be notorious for its excess, but some of The Strip’s biggest developers are now looking for ways to reduce their environmental impact. The result is infusing a new kind of green—from LED lamps to geothermal heat pumps—into a region with limited natural resources."

New Frontiers in Energy Management [for Water Utilities]

Water Efficiency, Mar./Apr. 2014, by Penelope B. Grenoble.
http://www.waterefficiency.net/WE/Articles/New_Frontiers_in_Energy_Management_24639.aspx

"Energy management has become a matter of necessity in states like California, less enthusiastically embraced in states where energy costs are lower. But take a closer look, and you’ll discover that energy and operational efficiency go hand in hand—and that managing energy costs goes beyond simply equipping a pump with a variable speed drive."

To Save Energy We Must Also Save Water

Insulation Outlook, Nov. 2013, by Jessica Kennedy.

"The connection between energy and water, often referred to as the "energy-water nexus," is collecting attention from business leaders, policy makers, and citizens alike. In short, this term refers to the close link between water and energy. Water is used in nearly every aspect of energy production. Saving energy will save water, and saving water will save energy."
