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.

 


Trends in Industrial Motors and Drives

Design News, Feb. 2014, by Al Presher.

"New motor and drive systems are continuing to focus on several main design goals: more intelligent performance, higher energy efficiency, and flexible integration options. The result is macro trends that are putting increased focus on support for a broader set of motor types, advanced cooling options, and built-in safety features, along with tighter integration of motor-drive solutions and decentralized control."

Wind Proves it Can Hold Its Own in Tough Times

Wind Power Monthly, Feb. 2014, by David Milborrow.

"The increasingly competitive position of wind as an electricity-generating source has been highlighted in Windpower Monthly for some time, but in 2013 a number of influential international organisations, such as the International Energy Agency and the World Energy Council, also reflected this view. The exact position of wind vis a vis cost comparison varies, depending on the price of competing fuels, but the debate over the relative economics of wind and nuclear power has acquired clear evidence over the past 12 months that wind is cheaper than nuclear."

New Refrigeration Efficiency Standards To Take a Bite out of Supermarket and Restaurant Energy Costs

American Council for an Energy-Efficient Economy (ACEEE), Feb. 28, 2014, by Joanna Mauer.

"The Department of Energy (DOE) issued a final rule for strong new efficiency standards today that will take a big bite out of the energy consumption of the refrigerators and freezers used in supermarkets, convenience stores, restaurants, and commercial kitchens. The significant reductions in energy use that we’ll see with the new standards are made possible by the availability of technologies including LED lighting and occupancy sensors, high-performance glass doors, and high-efficiency motors, which all provide big efficiency gains." Includes a link to the final rule.

Is Your Building Conducive to the Installation of a Green Roof?

"Despite the potential, installing a green roof is not a decision to be taken lightly. There are several structural and site/location considerations to take into account. The most recent news of a probable green roof collapse at a Latvian supermarket should give one pause. Before allocating the time and resources, facility owners and managers should weigh the pros and cons of a green roof and what to keep in mind during the planning stages."

Micro-Inverters are Moving Up to the Big Leagues: Opinions Differ on the Future of AC modules in Large PV Installations

Solar Industry, Feb. 2104, by Michael Puttre.
