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.

 


Developing 2,400+ MW of Hydro in North America

Hydro Review, Nov. 2015, by Elizabeth Ingram.
http://www.hydroworld.com/articles/hr/print/volume-34/issue-9/articles/developing-2-400-mw-of-hydro-in-north-america.html

"This article provides details about development work ongoing (or completed in 2015) at 10 hydro projects in the U.S. and Canada. This is just a representative sample and not intended to be comprehensive. Read on to learn who is developing these projects, where they are located, what it cost to develop them, how they got financing and much more."

"July 2015's 'Basics of Well-Mixed Room Air Distribution' described how conditioned air moves throughout a space. In the Fundamentals at Work article, we discuss where the conditioned air comes from by exploring the most predominant products in use today: commercial building variable air volume (VAV) terminal units."

Renewables Poised to Deliver Climate Solution

North American Clean Energy, Nov. 2015.
http://www.nacleanenergy.com/articles/21891/renewables-poised-to-deliver-climate-solution

"Emission reductions from renewables, coupled with energy efficiency improvements, must be at the heart of any effort to limit global temperature rise to two degrees Celsius, according to a report released by the International Renewable Energy Agency (IRENA). REthinking Energy 2015 – Renewable Energy and Climate, finds that achieving a 36% share of renewable energy by 2030 would result in half of all emission reductions needed to maintain a two degree pathway. Energy efficiency measures could supply the rest."

"From Maine to Hawaii, regulators continue to be caught between the power of utilities and the passion of renewables advocates on a slew of distributed energy issues, and a new report points out that they aren't likely to subside anytime soon."

What Are Transient Loads, and How Do I Reduce the Effect On My Turbines?

Wind Systems, Oct. 2015, by Doug Herr.
http://www.windsystemsmag.com/article/detail/1039/what-are-transient-loads-and-how-do-i-reduce-the-effect-on-my-turbines

"In the wind industry today, there is more discussion than ever on loads in the drivetrain of turbines. A significant amount of work has been done over the past few years to show that transient loads, particularly transient torque reversal loads, are occurring more often than expected. NREL’s Gearbox Reliability Collaborative has discussed transients and developed test cells to better understand the dynamics within the drivetrain."

What Owners Need to Know About... Pump Operation and Maintenance

"When the efficiency of a facility’s plumbing and HVAC systems is maximized, building owners realize energy- and operational-cost savings. Optimal efficiency can be achieved through seasonal maintenance and best practices regarding water pumps."

HVAC Contractors Prepare for DOE Efficiency Mandates

Air Conditioning/Heating/Refrigeration News, Oct. 18, 2015, by Joanna R. Turpin.
http://www.achrnews.com/articles/130794-hvac-contractors-prepare-for-doe-efficiency-mandates

"At the beginning of the year, the U.S. Department of Energy’s (DOE’s) minimum efficiency standards for residential air conditioners and heat pumps went into effect, dividing the country into three regions — North, South, and Southwest. The standards dictate that contractors in the latter two regions are allowed to install 13-SEER heat pumps and air conditioners until mid-2016 (or until supplies run out); then, they must only offer 14-SEER (or higher) equipment. Many HVAC distributors in those regions stocked up on 13-SEER equipment ahead of the deadline and are happy to see that their bets paid off as the inventory flew off the shelves."
