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.

Blades & Rotors [Turbines]

Business Energy, Jul/Aug 2015, by Carol Brzozowski.{}

"Savings and reliability from turbines and microturbines."

Schools Save Energy with CHP

Air Conditioning, Heating & Refrigeration News, Aug. 3, 2015, by Jen Anesi.

"With elementary and secondary schools tightening their purse strings, and with post-secondary institutions seeing a drop in enrollment numbers over the past couple years, schools across the nation are looking for ways to cut costs. Increasingly, they are turning to cogeneration as a way to save money while also being more environmentally friendly. And, while cogeneration is still largely an industrial process, the market has significant potential for educational institutions coast to coast."

Understanding Cogeneration Systems

Pure Power (supplement to Consulting-Specifying Engineer), Summer 2015, by Jerry Schuett and David Cummingham.

"Cogeneration systems—also known as combined heat and power (CHP) systems—generate both electricity and usable thermal energy. These systems typically are used on campuses that have high heat load requirements." Describes three CHP system prime movers: back-pressure steam turbine, combustion turbine, and reciprocating engine.

Barriers to Industrial Energy Efficiency: Report to Congress

U.S. Department of Energy, June 2015.

"The industrial sector has shown steady progress in improving energy efficiency over the past few decades, and energy efficiency improvements are expected to continue..... There are barriers, however, that impede the adoption of energy efficient technologies and practices in the industrial sector. This report examines these barriers and identifies successful examples and opportunities to overcome these barriers."

Biogas-To-Energy Helps A New York Facility Toward Self-Sufficiency

Treatment Plant Operator, July 2015, by Doug Day.

"Ithaca’s clean-water plant has boosted biogas production and energy generation in a project that will yield $9 million in guaranteed savings over a 20-year contract. The Ithaca (New York) Area Wastewater Treatment Facility now generates nearly half its electricity on site, and the plant team hopes a new biogas system can eventually meet most if not all power needs."

Barriers to Industrial Energy Efficiency: Report to Congress

U.S. Department of Energy, June 2015.

"This report examines barriers that impede the adoption of energy efficient technologies and practices in the industrial sector, and identifies successful examples and opportunities to overcome these barriers. Three groups of energy efficiency technologies and measures were examined: industrial end-use energy efficiency, industrial demand response, and industrial combined heat and power. This report also includes the estimated economic benefits from hypothetical Federal energy efficiency matching grants, as directed by the Act."

Dubuque [IA] Resource Recovery Facility Keeps It Sustainable

Treatment Plant Operator, June 2015, by Doug Day.

"An Iowa city’s $38 million [wastewater treatment] facility renovation includes combined heat and power, biosolids reuse, effluent heat recovery, water-saving landscaping, and more."

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

District Energy, 2nd Quarter 2015, by William J. DiCroce.

"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."

Small is Beautiful: Heat Pumps in Small-Scale Cogeneration

Cogeneration & On-Site Power Production, May-June 2015, Jan De Wit.

"Denmark has recently seen a growing number of cogeneration units installed in care homes, sports centres, schools and other municipal buildings. These installations have shown high annual operation hours, short ROI and significant CO2 savings. [The author] looks at how they do it."

Distributed Power’s Rising Importance for U.S. Electrical Infrastructure

Power Magazine, May 2015, by Devon Manz and others.

"Renewable generation may be the most talked-about form of distributed power these days. However, historically, engine- and turbine-based smaller-scale generation—strategically located where needed by loads or for grid support—has supplied valuable distributed power. For many reasons, the roles for distributed power provided by rotating and reciprocating equipment continue to increase."
