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 to Make the Utility of the Future an Energy-Efficient One: New ACEEE Report Series

American Council for an Energy-Efficient Economy (ACEEE), June 10, 2015, by Maggie Molina. http://aceee.org/blog/2015/06/how-make-utility-future-energy "Utilities have traditionally earned profits by simply selling more energy and building more power plants and infrastructure, which put their financial motivations squarely at odds with the goal of greater energy efficiency. Luckily, that business model has started to change, which is good news for the nation’s economy, environment, and for consumers who want more options for saving energy in their homes and businesses. With the proper regulatory tools in place, utilities’ financial motivations can be aligned with energy efficiency outcomes. ACEEE has been researching this issue for years, and today we are releasing a series of three new reports on a range of topics related to utility business models and energy efficiency." 1) Policies Matter: Creating a Foundation for an Energy-Efficient Utility of the Future 2) Beyond Carrots for Utilities: A Nat ...

Renewables Share of U.S. Energy Consumption Highest Since 1930s

Today in Energy (EIA), May 28, 2015, by Mary Joyce.
http://www.eia.gov/todayinenergy/detail.cfm?id=21412

"Renewable energy accounted for 9.8% of total domestic energy consumption in 2014. This marks the highest renewable energy share since the 1930s, when wood was a much larger contributor to domestic energy supply."

So, You Have A Boiler System

Engineered Systems, June 2015, by Marcia Karr.

"Whether it takes the form of low-cost adjustments and calibration, targeted replacements within the system, or a more substantial retrofit project when large equipment has run its course, you almost always have a good move available to conserve energy and expense. Boiler retrofits can reduce operating costs, reduce greenhouse gas emissions, and provide better reliability.  The primary focus of a boiler retrofit is to accomplish these goals without compromising comfort, safety, or quality. This article provides recommendations about three types of retrofits."

Key Drivers for Energy Storage Adoption: Distributing Reliable, High-Quality Power With a Range of Resources

North American Clean Energy, May/June 2015, by Chris Thompson.
http://www.nacleanenergy.com/magazine/mayjune_2015/index.html#p=8

"There is substantial buzz surrounding grid-tied energy storage. But what are the drivers for grid-tied storage today? There are key industry trends propelling the adoption of energy storage technology, including: increased renewables penetration, Federal Energy Regulatory Commission (FERC) orders, battery prices, and state mandates. The overall benefits of storage have evolved over the past few years, and grid-tied energy storage will continue to be an important consideration for the future of the grid."

Safety and Energy-Saving Resulting from Early Detection and Prevention of Leakage of Low-Flammable Refrigerants

IEA Heat Pump Centre Newsletter, #33 2015, by Masahide Sumi. [Open PDF then scroll or jump to page 22.

"Leakage of refrigerants represents a high cost in terms of the energy required in refrigeration and air conditioning devices. As it is expected that low-flammable refrigerants will be used in many devices in the future, this issue can be very important for the global environment, energy saving and safety. The following article describes detection systems which can easily detect and identify leakage at an early stage, and a method which can easily prevent leakage from plumbing and joints of air conditioning equipment."

Full "Green Steam" Ahead in Boston: CHP Project Advances Region's Environmental Goals

District Energy, 2nd Quarter 2015, by William J. DiCroce.
http://www.districtenergy-digital.org/districtenergy/2015Q2?folio=12#pg14

"One of the oldest cities in the United States, Boston is supported by an innovative district energy system that integrates thermal energy recycled from the electric generation process for heating and cooling. Since acquiring the district system in 2005, Veolia North America has made significant investments to improve network efficiency and reduce environmental impacts, culminating in the completion of its $112 million 'green steam' pipeline project in 2014."

2015 Wind Turbine Buyer’s Guide: Why, Where & How To Do Wind Electricity

Home Power Magazine, May/June 2015, by Ian Woofenden & Roy Butler.
http://www.homepower.com/articles/wind-power/equipment-products/2015-wind-turbine-buyer%E2%80%99s-guide

"Making electricity with the wind is not easy. As seasoned wind-energy installers with decades of experience, we—as well as thousands of others who live with home-scale wind turbines—tell a challenging tale. And the small wind industry today reflects those challenges, with long-established companies struggling and going under while the cost of reliable solar-electric modules continues to drop. If you think you want a wind-electric system, first think smart, then realistically."

Fan-Efficiency Metrics

HPAC Engineering, May 2015, by Dustin Meredith and Jeanne Harshaw.
http://hpac.com/iaq-ventilation/fan-efficiency-metrics

"Air Movement and Control Association (AMCA) International estimates fans account for 30 to 40 percent of commercial-building HVAC energy consumption. Improving fan efficiency, therefore, is an important step toward reducing global, overall energy use."

The Environmental Sustainability of Existing Buildings: Refurbish or Replace?

Circular Ecology, May 19, 2015, by Dr. Craig Jones.
http://www.circularecology.com/news/the-environmental-sustainability-of-existing-buildings-refurbish-or-replace#.VWZRE2zbIWo

"There comes a time in the life of every building where extensive refurbishment is required. For many a building this seems to bring with it thoughts of starting again – essentially to demolish and ‘rebuild’. The normal practice in modern times seems to be the preference to demolish and replace. Whereas conservationists naturally prefer to retain existing structures so to repair them and bring them back to their former glory. This latter approach retains the existing character and heritage of a building, but proponents of the ‘remove and replace’ philosophy ague about their reduced energy performance."

How Energy Efficiency Financing Can Help States Meet Clean Power Plan Goals

American Council for an Energy-Efficient Economy (ACEEE), May 27, 2015.
http://aceee.org/blog/2015/05/how-energy-efficiency-financing-can

"Today, ACEEE is releasing the second in a series of step-by-step guides that help states claim emissions reductions resulting from energy efficiency programs and policies. Navigating the Clean Power Plan: A Template for Including Energy Efficiency Finance Programs in State Compliance Plans is focused on helping states incorporate financing programs and policies into their plans for complying with the EPA Clean Power Plan. The tool provides an overview of some types of financing approaches that may be well suited for Clean Power Plan compliance."
