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.

 


Uncovering the Cost Benefits of a Good Lighting Circuit Design

"Iterative voltage drop calculations are some of the most tedious and time-consuming components of an electrical design process. This is especially true for large lighting installations, such as those found in parks and parking lots as well as roads and highways. As a result, it is common for designers to oversimplify voltage drop calculations in a lighting design. With the lighting industry trending toward LED use, it is becoming increasingly common to string large quantities of luminaires on a single circuit due to the decreased load per luminaire. Now more than ever, detailed voltage drop calculations can avoid over engineering of lighting systems and substantially decrease project costs."

LEDs Still a Mystery to Many Contractors

"As LED products continue to flood the marketplace, electrical contractors must balance the appeal of online buying expedience with the need to fully grasp a technology still shrouded in uncertainty. Held up as one of the proven, readily deployable technologies that could put a big dent in global energy consumption over time, LED lighting products are drawing the interest of ever more electrical contractors looking for avenues into the lucrative and growing energy-efficiency market."


Distributed Power’s Rising Importance for U.S. Electrical Infrastructure

Power Magazine, May 2015, by Devon Manz and others.

"Renewable generation may be the most talked-about form of distributed power these days. However, historically, engine- and turbine-based smaller-scale generation—strategically located where needed by loads or for grid support—has supplied valuable distributed power. For many reasons, the roles for distributed power provided by rotating and reciprocating equipment continue to increase."

How Utilities and Policymakers Can Maintain and Boost Renewable Energy's Value

"Grid operators have overcome the technical barriers to integrating 30% solar PV or 40% wind on their systems. Now only the economics stand in the way, as the value of renewables to utilities can change, and often declines, as their penetrations increase. But, new research shows that barrier could be ready to crumble as well."

USDA Grant Supports Installation of Pellet Boiler in N.H. school

Biomass Magazine, April 27, 2015, by Rep. Annie Kuster's Office [NH].

"Rep. Annie Kuster, D-N.H., recently announced two grants from the USDA’s Rural Development program that will support projects in two New Hampshire communities.  The Bethlehem School District has received a $30,000 grant that will be used to replace an oil-fired hot water boiler heating system at Bethlehem Elementary School with wood pellet boilers, and the town of Stratford has received a $15,000 grant to improve its town garage, which houses all town vehicles."

Demand Response Pilot Launched [Energy Northwest & BPA]

BPA Journal, May 2015. -- scroll to page 3 of the PDF.

"Industry representatives from across Washington got the red carpet
treatment as Gov. Jay Inslee recognized nine companies for their exceptional commitment to saving energy at the
Washington Industrial Energy Leaders awards March 25 at the capital in Olympia."

BERC Launches Updated Community-Scale Wood Heating Database

Biomass Magazine, April 28, 2015.
http://www.biomassmagazine.com/articles/11868/berc-launches-updated-community-scale-wood-heating-database

"The Biomass Energy Resource Center [BERC], a program of the Vermont Energy Investment Corp., has launched a re-tooled web-based database for tracking the advancement of modern wood heating throughout North America. The newly revised searchable database houses key information on existing community-scale modern wood heating and combined heat and power systems across the U.S. and Canada, as well as an archive of links to case studies."

Batteries Are Carving Out Space on the Grid

Power Magazine, May 2015, by Thomas W. Overton.

"Falling prices and technological improvements have brought battery storage systems into direct competition with traditional distributed generation, demand response, and peaking generation resources. But making one work efficiently and profitably is not just plug and play."

Developing a Pump System Assessment with Energy Cost Balance Sheets

Engineered Software, Inc., May 2015.
http://eng-software.com/company/press/2015/5/developing-a-pump-system-assessment-with-energy-cost-balance-sheets/

"The first step in the assessment involves developing an Energy Cost Balance Sheet for the way the system is currently operating.  We can then identify system improvement alternatives and develop an Energy Cost Balance Sheet for each proposed alternative.  These results provide the plant’s financial management team with the data needed to develop a course of action based on the potential risk/ reward."
