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.

"The Village of Ridgewood (N.J.) Water Pollution Control Facility is cutting its costs by adding biogas and solar power generation — that’s nothing new. But leaders in this village of 26,000 did it without spending money. Instead, they entered an agreement with other parties who provided the funds in exchange for sharing in project savings and revenue."

Coal is Going, Going... Gone?

"Coal power was the backbone of American industry for the last 100 years. But by 2020, the U.S. Energy Information Administration (EIA) predicts that about 60 gigawatts (GW) of coal-fired capacity will be retired. That's 6.2% of all U.S. capacity, according to calculations based on NERC data."

ERVs Gain Traction in New and Old Projects

Air Conditioning, Heating & Refrigeration News, Apr. 21, 2014, by Jen Anesi.

"The more outside air a building pulls in, the harder the HVAC system will have to work to condition that air. Heat recovery ventilators (HRVs) help mitigate that energy loss by extracting heat from exhaust air and applying it to the incoming fresh air. Similarly, energy recovery ventilators (ERVs) extract both heat and humidity from exhaust air in order to pre-treat fresh air." Article includes a "Product Showcase" of some of the new HRV and ERV products.

Balancing Home-Performance Demands with Ventilation Needs

Air Conditioning, Heating & Refrigeration News, Apr. 21, 2014, by Jen Anesi.

"While new homes are being built tighter than ever, more and more contractors are helping their customers identify and rectify sources of energy loss in their homes, ensuring future energy savings and comfort for homeowners. But, as contractors seal up these homes, they also need to consider proper ventilation, avoid common mistakes, and follow industry protocols to ensure occupant health and safety."

"Gov. Jay Inslee today signed an executive order outlining a series of steps to cut carbon pollution in Washington and advance development and use of clean energy technologies."

Amory's Angle: Ramping Up Renewable Electricity

Rocky Mountain Institute, Winter 2014, by Amory B. Lovins.
http://www.rmi.org/winter_2014_esj_ramping_up_renewable_electricity

"Many people in the electricity industry long thought that the two renewable sources of electricity that vary widely over time—windpower and solar photovoltaics (PVs) —could provide only a few percent of total generation without endangering reliability. Those who still believe this now face increasingly severe reality tests.

As we’ll see, Germany and other countries are successfully powering their grids with astonishingly high fractions of renewable generation by combining five techniques: a) leveraging diverse generation sources across interconnected regional and national grids, b) improving renewables’ forecasting and predictability, c) integrating dispatchable renewables, d) adding distributed storage, and e) leveraging demand response."




What Owners Need to Know About ... Evaporative-Cooling Equipment

Heating/Piping/Air Conditioning Engineering, Apr. 2014, by June Galloway. (Free registration is required to view full-text of article.)
http://hpac.com/air-conditioning/what-owners-need-know-about-evaporative-cooling-equipment

"Evaporative-cooling equipment is selected to provide a fluid (usually water) to a system at a certain temperature and flow rate. If the temperature of the fluid delivered to a system (chiller) is higher than desired, the system will suffer increased wear and tear and usage. Decreasing leaving-water temperature by just 2°F can lower electricity expenditures by 6 percent.

Routine inspection and maintenance is paramount in achieving desired temperature and flow rate, and it plays an important role in extend operating life
