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.

 


How Do You Size a VFD?

Flow Control, Sept. 2016, by Jeff Bergman and Sean Fitzpatrick.
http://www.flowcontrolnetwork.com/how-you-size-vfd

"Confusion often surrounds the proper sizing of variable frequency drives (VFDs), and sometimes, knowing when and how to choose one may be difficult. Actually understanding what a VFD does might make this decision easier and the requirements less difficult to understand."

BPA 2016-2017 Implementation Manual

Bonneville Power Administration, Aug. 22, 2016.
https://www.bpa.gov/EE/Policy/IManual/Documents/IM_August2016.pdf

Effective Oct. 1, 2016 - "Based on BPA’s Regional Dialogue policy, BPA commits to achieving the share of the Council’s Power Plan regional energy efficiency target that represents the load of BPA’s public power customers. BPA reports savings to its target from three major categories: programmatic, momentum and market transformation. The [Implementation] Manual covers only programmatic savings that are reportable to BPA’s targets."

Studies Suggest That Past Rates of Energy Efficiency Improvement Can Be Sustained

ACEEE, Sept. 8, 2016, by Steven Nadel,
http://aceee.org/blog/2016/09/studies-suggest-past-rates-energy

"Can efficiency improvements achieved in past decades be sustained in the future?  How much impact does the rebound effect have on energy efficiency potential out to 2030, or even 2050? To answer these questions, I was invited to write a paper entitled The Potential for Additional Energy Efficiency Savings Including How the Rebound Effect Could Affect This Potential. The paper appears in the current issue of Current Sustainable/Renewable Energy Report (September 2016), an academic journal published by Springer." (Link included in article.)

Expanding the Energy Efficiency Toolbox Through Green Banks

ACEEE, Sept. 7, 2016, by Annie Gilleo.
http://aceee.org/blog/2016/09/expanding-energy-efficiency-toolbox

"In a new report from ACEEE, we review the progress of six green banks and four additional financing entities that serve similar functions. Our goals were to understand how green banks are working in specific market sectors and to identify promising strategies and lessons learned, with a particular focus on energy efficiency. If more states are looking to green banks to stretch public dollars, fill market gaps, and ramp up clean energy investment, we want to know how the early results and lessons learned can shape the next round of green bank deployment."

"Robin Roy, an NRDC consultant, explains why community energy storage often falls between the gaps in federal energy policy and what can be done about the problem."

Nanogrids and Microgrids are Keys to Decentralizing the Energy Infrastructure

Energy Manager Today, Sept. 13, 2016, by Carl Weinschenk.
http://www.energymanagertoday.com/nanogrids-and-microgrids-are-keys-to-decentralizing-the-energy-infrastructure-0126982/

"Nanogrids essentially is the microgrid concept — creating islands of power generation that rely on renewables and can either work in concert with or independently of the utility — taken to its logical conclusion. Indeed, a big piece of the value proposition may be that nanogrids are so small that they ease the transition to decentralized power."

Innovation Ups Irrigation IQ: Sensors, Controllers, and Flow Meters Get Smarter

Water Efficiency, Sep/Oct 2016, by Lyn Corum.

"All growers want to see their crops, gardens, and landscapes flourish. Competition among manufacturers of irrigation controllers, sensors, and flow meters is driving innovation at high speed in this digital age, to satisfy the market."

Energy Secretary Moniz and Interior Secretary Jewell Announce New National Offshore Wind Strategy to Drive Deployment

Energy.gov, Sept. 9, 2016.
http://energy.gov/articles/energy-secretary-moniz-and-interior-secretary-jewell-announce-new-national-offshore-wind

"U.S. Secretary of Energy Ernest Moniz and U.S. Secretary of the Interior Sally Jewell today announced the publication of a collaborative strategic plan to continue accelerating the development of offshore wind energy in the United States, the National Offshore Wind Strategy: Facilitating the Development of the Offshore Wind Industry in the United States, which could help enable 86 gigawatts of offshore wind in the United States by 2050. The strategy details the current state of offshore wind in the United States, presents the actions and innovations needed to reduce deployment costs and timelines, and provides a roadmap to support the growth and success of the industry."

Comparing Polystyrenes: Looking At the Differences Between EPS and XPS

The Construction Specifier, Sep. 2016, by Jason Burgess.
http://www.constructionspecifier.com/comparing-polystyrenes-looking-at-the-differences-between-eps-and-xps/

"Insulation is a critical component to specify when designing a functional, cost-effective, and energy-efficient building. One method to insulate a building is by installing 50 to 152 mm (2 to 6 in.) of rigid foam insulation on the exterior side of the wall framing. Two of the most frequently installed types of rigid foam insulation are expanded and extruded polystyrene (EPS and XPS). Both serve the same basic function: providing a means to manage the passage of heat in a building system. However, they differ in important ways."

Net Positive Energy Buildings

ASHRAE Journal, Aug. 2016, by Dylan Connelly and Laura Fedoruk. (Article Summary only.)
https://www.ashrae.org/resources--publications/periodicals/ashrae-journal/features/net-positive-energy-building

"DPR Construction’s retrofitted San Francisco headquarters building achieved approximately 20% net positive energy its first year of operation using efficient systems including HVAC, electrical and PV. And, in late 2015, it was certified as a net zero energy building. The office building demonstrates the capabilities of integrated, innovative, and replicable design. And, it proves that sustainable buildings can reduce energy use and improve indoor environmental conditions, while being cost effective. It has become a hub for learning and collaborating on many sustainably minded design projects."
