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.

 


Examining the Net Savings Issue: A National Survey of State Policies and Practices in the Evaluation of Ratepayer-Funded Energy Efficiency Programs

ACEEE, Jan. 15, 2014, by Martin Kushler, Seth Nowak & Patti Witte.
http://www.aceee.org/research-report/u1401

"Determining the net savings impacts of a program is one of the most prominent and longstanding challenges in the utility energy efficiency field. ACEEE conducted a national review of state approaches to the net savings issue in order to help policymakers, regulators, utilities, and other interested parties better understand this issue and how their peers are addressing it."

Energy Conservation Program for Consumer Products: Proposed Determination of Hearth Products as a Covered Consumer Product

U.S. Department of Energy, Energy Efficiency and Renewable Energy Office (EERE),  Dec. 31, 2013.
http://www.regulations.gov/#!documentDetail;D=EERE-2013-BT-DET-0057-0002

"The U.S. Department of Energy has tentatively determined  that hearth products meet the criteria for covered products because classifying products of such type as covered products is necessary or appropriate to carry out the purposes of EPCA (which is to improve the efficiency of covered consumer products to conserve the energy resources of the Nation), and the average annual U.S. household energy use for hearth products is likely to exceed 100 kilowatt-hours (kWh) per year."

Researchers: There is more to biofuel production than yield

Biomass Magazine, Jan. 16, 2014.
http://www.biomassmagazine.com/articles/9901/researchers-there-is-more-to-biofuel-production-than-yield

"When it comes to biofuels, corn leads the all-important category of biomass yield. However, focusing solely on yield comes at a high price. In the current issue of the Proceedings for the National Academy of Sciences, Michigan State University researchers show that looking at the big picture allows other biofuel crops, such as native perennial grasses, to score higher as viable alternatives."
