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.

 


Laboratory Assessment of Stiebel-Eltron Accelera 220 E Heat Pump Water Heater

Northwest Energy Efficiency Alliance (NEEA), July 30, 2015, by Nicholas Kvaltine and Ben Larson (Ecotope, Inc.)
http://neea.org/docs/default-source/reports/laboratory-assessment-of-stiebel-eltron-accelera-220-e-heat-pump-water-heater.pdf?sfvrsn=4

"The Northwest Energy Efficiency Alliance (NEEA) contracted with Ecotope, Inc. and Cascade Engineering Services, Inc. to conduct a laboratory assessment of the Stiebel-Eltron Accelera 220 E heat pump water heater (HPWH) for northern climate installations. Cascade Engineering evaluated the Accelera 220 E using a testing plan developed by Ecotope to assess HPWH performance. Overall, the results suggest that the Stiebel-Eltron Accelera 220 E is a highly-efficient water heater."

Green Doesn’t Mean What it Used To in Today’s Utility Industry: How Utilities are Dealing with Legalized Marijuana

Northwest Public Power Association Bulletin, July 2015, by Lance Robertson. (Scroll of jump to page 26.)

"Utilities are looking at a number of issues, concerns, and opportunities, from the amount of electricity the cannabis industry uses to ensuring that the added power demand won’t reduce the reliability or safety of localized electric distribution systems. Many public utilities also are concerned that increased demand for electricity will force them to raise electric rates for all customers, while a handful of utilities see the emerging commercial cannabis industry as an opportunity to boost revenues lost due to the lingering effects of the Great Recession in the Pacific Northwest."

Opportunities for Action on Energy Management Information Systems for Industrial Customers: A Report for Program Administrators

"This report helps NEEA's funders and other program administrators determine how to move forward with energy management information systems (EMIS) with their industrial customers. It offers ideas for the future as well as immediate next steps for program administrators.

This publication builds on NEEA’s Inventory of Industrial Energy Management Information Systems (EMIS) for M&V Applications, and on two new guides - the
Guide to Selecting an EMIS and the Guide to Using an EMIS."

Competitiveness of Renewable Energy and Energy Efficiency in U.S. Markets

Advanced Energy Economy Institute (AEE), June 2015.
http://info.aee.net/hubfs/PDF/RE-EE-Competitiveness.pdf?t=1438010695710

"Questions have been raised about whether renewable energy (RE) and energy efficiency (EE) resources can provide substantial emission reductions at reasonable cost under EPA’s proposed Clean Power Plan (CPP). These concerns reflect fundamental misperceptions about the performance and cost of today’s renewable energy and energy efficiency technologies, rooted in outdated information and perpetuated by inaccurate official market projections. This paper shows that RE and EE are competitive resources in today’s marketplace that will not only be cost-effective mechanisms for CPP compliance but should also be expected to grow strictly on the basis of competitiveness."

Which Energy Efficiency Policies Saved the Most Last Year?

American Council for an Energy-Efficient Economy (ACEEE), July 29, 2015, by Steven Nadel.
http://aceee.org/blog/2015/07/which-energy-efficiency-policies

"We are periodically asked how much different policies have saved and which policies have had the largest impact. In our recent report on energy efficiency progress over the past 35 years, we reviewed many current energy savings estimates and projections. Here I wanted to summarize which policies appear to be saving the most energy today, looking at estimated energy savings in calendar year 2014. Our estimates are summarized in the table below."

Why Your High-Efficiency-Lighting May Not Be Very Efficient At All

National Lighting Bureau News, July 14, 2015.
http://www.nlb.org/index.cfm?cdid=11138&pid=10213

"Silver Spring, MD: Imagine, if you will, the world’s most efficient lighting system; a system so efficient that it provides all the lighting needed by a 100-person workforce for  the fantastically small sum of just $100 per year; that’s $1 per person per year. Can a lighting system be any more efficient than that? Yes, it can, says National Lighting Bureau Chair James M. “Jim” Yorgey, P.E., LC, CTS: “While having a highly efficient lighting system is important, it’s even more important – from a bottom-line point of view – that the lighting system contribute to the enhanced efficiency of other systems that are affected by lighting, human systems in particular.”

Landmark Northwest Study Reveals Smart Grid Pros and Cons

Public Power Daily, July 20, 2015, by Elisa Wood.
http://www.publicpower.org/Media/daily/ArticleDetail.cfm?ItemNumber=44211

"A recently completed $178-million Pacific Northwest Smart Grid Demonstration Project led by Battelle demonstrated that smart grids are more efficient and resilient, according to a project report. The demonstration project was the largest of 16 smart grid demonstration projects funded by the U.S. Department of Energy under the American Recovery and Reinvestment Act of 2009. The effort encompassed more than 60,000 metered customers, many of them served by public power utilities in Idaho, Montana, Oregon, Washington and Wyoming."

3 Options for HVAC Energy Savings

Building Operating Management, June 2015, by James Piper.
http://www.facilitiesnet.com/hvac/article/3-Options-for-Energy-Savings-in-HVAC-Systems-Facilities-Management-HVAC-Feature--15949

"Even with today’s falling energy prices, facility managers are looking for ways to reduce the energy use of HVAC systems. New technologies and improvements in existing technologies are giving facility managers options. While advances can be seen in practically all HVAC systems, some of the most significant advances are coming in three particular areas: variable refrigerant flow systems, rooftop units, and geothermal systems."

Driving Data Center PUE, Efficiency

Pure Power (supplement to Consulting-Specifying Engineer), Summer 2015, by Bill Kosik.
http://www.csemag.com/single-article/driving-data-center-pue-efficiency/4bba5f95667a596a898be854d101e01e.html

"For the last decade, power usage effectiveness (PUE) has been the primary metric in judging how efficiently energy is used in powering a data center. PUE is a simple energy-use ratio where the total energy of the data center facility is the numerator, and the energy use of the information technology (IT) systems is the denominator."
