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.

 


More than Heat and Power: Cogeneration with New Gas Engine Technology

Cogeneration & On-Site Power Production, May/June 2014, by Michael Devine.
http://www.cospp.com/articles/print/volume-15/issue-3/features/more-than-heat-and-power.html

"Cogeneration today goes well beyond simultaneously generating electricity and hot water or steam. Today's usable engine outputs can also include heated air, chilled water produced by absorption chillers, and carbon dioxide from purified exhaust. In other words, a single engine-generator can produce two, three or four useful outputs at once. With today's generating technologies, electrical efficiencies up to 45% and total resource efficiencies upwards of 90% are achievable. And cogeneration systems do not necessarily need to operate full-time at full load to be cost-effective–low-cost and low-intensity configurations can bring attractive returns in many settings."

Micro-CHP: A Tool for Increased Market Access

Cogeneration & On-Site Power Production, May/June 2014, by Jan de Wit, Mads Moeller Melchiors and Laila Grahl Madsen.

"...present perspectives for increased CHP market penetration, as well as reduced primary fuel consumption and carbon savings based on one year's field testing of fuel cell-based micro-CHP units."

Hydrogen Fuel Finally Graduating From Lab to City Streets

Bloomberg Business Week, June 2014, by Christopher Martin.

"All aspects of system operations are tested by unique challenges as more variable energy resources are connected to the grid."

Cool Policies for Cool Cities: Best Practices for Mitigating Urban Heat Islands in North American Cities

American Council for an Energy-Efficient Economy (ACEEE), June 17, 2014, by Virginia Hewitt, Eric Mackres, Kurt Shickman. (Free registration required to view full report.)

"The urban heat island (UHI) effect is a global phenomenon in which dark, impermeable surfaces and concentrated human activity cause urban temperatures to be several degrees hotter than those in surrounding areas. Urban heat islands impose negative effects on local and global public health, air quality, energy consumption, resilience, quality of life, stormwater management, and environmental justice. Cities across North America experience and mitigate the impacts of UHIs. We conducted a review of the UHI mitigation activities of 26 North American cities and distributed a questionnaire to local government contacts to gather information."

High-Tech Window Glazing

Green Builder, June 2014, by Suchi Rudra. (Scroll or jump to page 49.)

"When it comes to energy efficiency, windows are problematic; they're essentially holes in an otherwise insulated wall. Glass makes up about 15 percent of the wall space in an average home, and inefficient windows can cost over $700 a year in wasted heating and cooling costs. This loss accounts for approximately 2 percent of all energy consumption in the U.S. Upgrading window products, whether you retrofit or replace, means upgrading building performance and cutting back on hundreds of dollars in energy bills."

Rental Renaissance

"Well designed, energy efficient. Located in walkable neighborhoods near public transportation. In cities across the country, the humble apartment is receiving a green makeover."

A Survey of State-Level Cost and Benefit Estimates of Renewable Portfolio Standards

National Renewable Energy Laboratory (NREL) & LBNL Technical Report, NREL/TP-6A20-61042 & LBNL-6589E, May 2014.
http://emp.lbl.gov/sites/all/files/lbnl-6589e.pdf

"This report surveys and summarizes existing state-level RPS cost and benefit estimates and examines the various methods used to calculate such estimates. The report relies largely upon data or results reported directly by electric utilities and state regulators."
 

Taming an Energy Hog with Efficiency Standards [Furnace Fans]

American Council for an Energy-Efficient Economy (ACEEE), June 25, 2014, by Joanna Mauer.
http://aceee.org/blog/2014/06/taming-energy-hog-efficiency-standard%20

"The Department of Energy (DOE) issued new efficiency standards today that will dramatically reduce the energy use of a little-known home energy hog. Furnace fans, which circulate heated and cooled air throughout a home, consume more than twice the electricity in a year as a typical new refrigerator. The new standards will cut the cost to power furnace fans by about 40% and also deliver improved comfort."

ASME EA-4-2010 - Energy Assessment for Compressed Air Systems. What’s it all about?

Compressed Air Best Practices, June 2014, by Joe Ghislain.
http://www.airbestpractices.com/standards/food-grade-air/asme-ea-4-2010-energy-assessment-compressed-air-systems-what-s-it-all-about

"The ASME EA-4 standard takes the same system approach that is taught in the Compressed Air Challenge® Fundamentals and Advanced Compressed Air System Management courses and provides a prescriptive but scalable process that can be tailored to each facility. Along with system definition, it sets requirements for organizing and conducting the assessment, analyzing the data, and reporting and documenting of the findings."
