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.

 


Pump System Optimization in Pulp & Paper: High-Value Target Applications

Pumps & Systems, July 2016, by Mike Pemberton.
http://www.pumpsandsystems.com/print/pumps/july-2016-pump-system-optimization-pulp-paper-high-value-target-applications

"In most pulp and paper applications, energy and unscheduled maintenance are two of the largest components of ownership cost. For this reason, improving pump efficiency is key to pump system optimization. Although certain mechanical and control modifications can improve reliability, selecting the best hydraulic fit is an often overlooked approach to system optimization. Energy and reliability are two sides of the same coin: A good rule of thumb is that where there is excess energy beyond what is required to move fluid through the pipes, there will also be unreliability."

A Simplified Method of Determining the Efficiency of a Motor-Driven Centrifugal Pump

Pumps & Systems, July 2016, by Robert X. Perez.

"A common concern in processing plants is determining the pumping health—or efficiency—of centrifugal pumps. As pump impeller seals wear as a result of erosion and corrosion mechanisms, tight internal clearances open up and allow fluid to recirculate internally, gradually degrading performance. As wear progresses, a centrifugal pump will eventually become unable to perform its intended function. Periodically monitoring pump performance allows end users to identify internal degradation before a serious loss of capability occurs."

Commissioning and Design for 2016 Olympics

ASHRAE Journal, Jul 2016, by Ross D. Montgomery and Walter R. Lenzi.

"Beginning in 1994, the International Olympic Committee began to require environmental awareness as part of all Olympic Games. Over the years, the emphasis on sustainability grew, and the Rio 2016 Olympic Games in August is the latest example of the benefits gained by using these strategies. ASHRAE members and student members are a part of this high-profile project, as they provided commissioning and HVAC&R design services, especially at the Olympic Park. This venue is where most events will occur in Barra da Tijuca, located 21 miles (34 km) south of Copacabana beach."

Eugene Evaluating Safety of LED Lights

"Eugene city officials are evaluating the light emitted by new LED streetlights after the American Medical Association issued an official policy statement that it can be harmful to a person’s health."

New Heat Pump Water Heater Changes the Game

Northwest Energy Efficiency Alliance, July 2016.
http://neea.org/neea-newsroom/press-releases/press-release-detail/2016/07/05/new-heat-pump-water-heater-changes-the-game

"Today, A. O. Smith, the largest manufacturer and marketer of water heaters in North America, introduced a dramatically efficient new model of heat pump water heater. Already three times more efficient than a standard electric water heater, A. O. Smith engineers refreshed the Voltex line to improve energy efficiency benefits and performance for homes in all climates, including homes that routinely deal with cold weather."

The Future of Air Conditioning for Buildings

U.S. Dept. of Energy, EERE, July 2016, by Navigant Consulting and Oak Ridge National Lab.
http://www.energy.gov/eere/buildings/downloads/future-air-conditioning-buildings-report

"This report characterizes the current landscape and trends in the global air conditioning (A/C) market, including discussion of both direct and indirect climate impacts, and potential global warming impacts from growing global A/C usage. The report also documents solutions that can help achieve international goals for energy efficiency and greenhouse gas (GHG) emissions reductions."

Irrigation Modernization Program Wins National Award

The Bulletin (Bend, OR), June 21, 2016.
http://www.bendbulletin.com/localstate/4445666-151/irrigation-districts-participate-in-program

"Eight irrigation districts in Central Oregon are taking part in a water-saving program that recently won a national award. The program seeks to modernize irrigation systems by replacing open canals with piping to keep water from evaporating or leaking while being diverted to farms and ranches."

Energy-Water Nexus Issues Heighten in the Face of Climate Change

ACEEE, Jul 8, 2016, by Steven Nadel.
http://aceee.org/blog/2016/07/energy-water-nexus-issues-heighten

"ACEEE and many others have noted the importance of the nexus between energy and water issues. Energy is used to move, treat, and heat water. Water is vital for producing energy, such as for cooling electric generating plants. Insufficient water availability can increase energy use for pumping and decrease energy production. Flooding can damage both energy and water systems. And there are many opportunities to promote both energy and water efficiency at the same time."

Forecasting Wind Energy Costs and Cost Drivers: The Views of the World’s Leading Experts

Lawrence Berkeley National Lab, June 2016, LBNL-1005717.
https://emp.lbl.gov/sites/all/files/lbnl-1005717.pdf

"This report summarizes the results of an expert elicitation survey of 163 of the world’s foremost wind energy experts, aimed at better understanding future wind energy costs and potential technology advancement. We specifically sought to gain insight on the possible magnitude of future cost reductions, the sources of those reductions, and the enabling conditions needed to realize continued innovation and lower costs. In implementing what may be the largest single elicitation ever performed on an energy technology in terms of expert participation, we sought to complement other tools for evaluating cost-reduction potential, including learning curves, engineering assessments, and other means of synthesizing expert knowledge."

Energy Trust Names NYSERDA Veteran As New Executive Director

Energy Trust of Oregon, June 7, 2016.
http://blog.energytrust.org/energy-trust-names-nyserda-veteran-new-executive-director/

"Energy Trust of Oregon appointed Michael Colgrove as the nonprofit organization’s new executive director. Colgrove will join Energy Trust after 15 years with the New York State Energy Research and Development Authority where he was both the director of the New York City office and director of multifamily programs. NYSERDA promotes energy efficiency and the use of renewable energy sources to reduce customer energy bills and greenhouse gas emissions, while accelerating economic growth."
