What Matters When Purchasing a Small Wind Turbine?

Solar Today, Spring 2016, by Mick Sagrillo.
http://solartoday.org/2016/05/what-matters-when-purchasing-a-small-wind-turbine/

"What makes a manufacturer worth considering? With the plethora of small wind web sites out there, it’s might seem daunting to try to ferret out the wheat from the chaff, who is a legitimate small wind manufacturer and who is a huckster. Actually, it is simpler than it appears. Remember the discussion about turbine certification? (ST Winter 2015/2016) This is your screen. Any manufacturer not listed with a certified turbine should not be considered, period. No matter what they promise or how much they plead. Do you want to be someone’s beta test site or do you want a working wind system for decades?"

Mapping Out Microgrids

On-Site Energy Management, Mar/Apr 2016, by Tom Bryan.
http://www.onsiteenergymanager.com/articles/4824/mapping-out-microgrids

"Every distributed generation project with islanding capability is unique and usually custom-made. There are, however, off-the-shelf methods of assessing and designing them. On-Site Energy Management's latest print issue lays out the fundamentals."

U.S. Microgrid Market Development

Power Magazine, May 2016, by Gail Reitenbach.
http://www.powermag.com/u-s-microgrid-market-development/

"Microgrids have been around for decades, but today, more potential customers, owners, technologies, and vendors than ever are part of the market. Increased interest in this special grid resource means there’s more competition, which is generally a good thing, but there are also new challenges."

New Cogen System Triples Energy Output from Biogas at Oregon WWTP

Biomass Magazine, May 2015, by Katie Fletcher.
http://www.biomassmagazine.com/articles/13229/new-cogen-system-triples-energy-output-from-biogas-at-oregon-wwtp

"On May 4, Clean Water Services, Energy Trust of Oregon and the Oregon Department of Energy formally announced the implementation of a new cogeneration system that converts wastewater and grease into renewable energy. The innovative system, which is part of Clean Water Services Durham Treatment Facility, is the third cogeneration system in Oregon to codigest fats, oils and grease (FOG)."

Measuring the True Costs and Benefits of Energy Storage, Part 2

North American Clean Energy, Mar/Apr 2016, by Katherine Von Burg.

"Part Two - How cycle life and environmental factors impact LCOE
In last month’s issue, Part One of this series began covering how checking a few simple performance metrics can help calculate the true costs and benefits of competing energy storage systems. Additionally calculating this levelized cost of energy (LCOE) can help distinguish between what might look like a good price up front from what’s actually a better buy in the long run."

Hydrogen and a New Paradigm for Electricity Storage

North American Clean Energy, Mar/Apr 2016, by Ken Brown.
http://www.nacleanenergy.com/articles/22731/hydrogen-and-a-new-paradigm-for-electricity-storage

"A new paradigm is needed for electricity storage in the wind energy market. Today, what passes for “grid storage” are technologies providing, at most, eight to 12 hours of discharge time. If electricity generation is to be successfully weaned from fossil fuels, storage must have more than 1,000 hours of discharge time to back up renewables when they are intermittent. Sometimes the wind does not blow and the sun does not shine for long periods of time. Long discharge time provides reliability."

Onsite Power: What's It Mean to Get to Zero

Net Zero Buildings, Mar. 2016, by Chuck Ross. -- Jump to page 24.
https://issuu.com/constructionbusinessmedia/docs/1603_nzb

"Net zero building has been a topic of conversation between architects and engineers for more than a decade, but there remains a significant lack of consensus over what 'net zero' actually means when it comes to the relationship between onsite energy consumption and generation."

Wind Plant Modeling Data Essential to Interconnections

North American Clean Energy, Mar/Apr 2016, by Jim Smith.
http://www.nacleanenergy.com/articles/22730/wind-plant-modeling-data-essential-to-interconnections

"Wind power developers often are not aware until the last minute before submitting an interconnection application that they are required to provide computer modeling data. Ignorance, in this case, certainly isn’t bliss, but a little awareness can make the process a lot less painful."

A Retrospective Analysis of the Benefits and Impacts of U.S. Renewable Portfolio Standards

Lawrence Berkeley Laboratory, Jan. 2016.
https://emp.lbl.gov/publications/retrospective-analysis-benefits-and

"This is the second in a series of reports exploring the costs, benefits, and other impacts of state renewable portfolio standards (RPS). This report focuses on the benefits and impacts of all state RPS programs, in aggregate, for the year 2013. Relying on a well-vetted set of methods, this report evaluates a number of important benefits and impacts in both physical and monetary terms, where possible, and characterizes key uncertainties."

Absorption Chillers For Institutional Occupancies

Engineered Systems, Feb. 2016, by Marcia Karr.
http://www.esmagazine.com/articles/97567-absorption-chillers-for-institutional-occpancies

"It's not necessarily a plug-and-play situation, but these chillers can play key roles and deliver meaningful savings in several scenarios. Waste heat, CCHP, standalone, and even renewable solar as part of the refrigeration cycle can all provide the setting for absorption success."
