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."

Wind Plant Modeling Data Essential to Interconnections

North American Clean Energy, Mar/Apr 2016, by Jim Smith.

"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."

The State of Wind Farm Underperformance Syndrome

Wind Systems Magazine, Mar. 2016, by Bruce H. Bailey.
http://www.windsystemsmag.com/article/detail/1149/the-state-of-wind-farm-underperformance-syndrome

"It is fair to expect that the energy output of an operating wind farm should be close to what it was designed to produce. If the wind conditions for a particular site are well-measured and the selected turbine is a well-known model, then logic would conclude that the energy prediction process is fairly straightforward. But is this an oversimplification? Industry experience has shown that it is, since the majority of operating wind farms don’t meet their predicted P50 energy values in an average year."

What Matters When Shopping for a Small Wind Turbine?

Solar Today, Winter 2015/2016, by Mick Sagrillo.

"You’ve done your research on wind energy and fully understand the concepts of fuel quality and quantity, and the importance of tower height. It’s time to start looking around for what different manufacturers offer. So, what do you need to consider when perusing various small wind web sites? The following are good fundamentals to keep in mind when shopping for any wind energy conversion system."

Teaming Up to Apply Advanced Manufacturing Methods to Wind Turbine Production

U.S. Department of Energy, February 1, 2016.
http://energy.gov/eere/articles/teaming-apply-advanced-manufacturing-methods-wind-turbine-production

"DOE’s Wind Program and Advanced Manufacturing Office, ORNL, Sandia National Laboratories (SNL), and other organizations are partnering to apply this advanced manufacturing technology to the production of wind turbine blade molds. By applying 3D printing to the manufacture of blade molds, it is possible to reduce costs and time associated with manufacturing, experiment with new capabilities, and improve design flexibility. Blades are some of the most important—yet costly—components of a wind turbine, so finding ways to reduce the cost of blade manufacturing will further reduce the costs of wind energy."

U.S. Wind Sees Second Strongest Quarter in History, Ready for 2016

Into the Wind (AWEA Blog), Jan. 27, 2016, by Hannah Hunt.

"The fourth quarter numbers are in, and they are impressive: the U.S. wind industry recorded its second strongest quarter in history. Combined with the best policy certainty it’s ever known, American wind is poised for a take-off."

Innovative Study Helps Offshore Wind Developers Protect Wildlife

U.S. Department of Energy, Oct. 27, 2015.
http://energy.gov/eere/articles/innovative-study-helps-offshore-wind-developers-protect-wildlife

"Thanks to a first-of-its-kind in-depth study of wildlife distribution and movements, the nation’s Eastern Seaboard is better prepared than ever for offshore wind energy."

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."

Outside-the-Box Renewable Energy Microturbines

"Rooftops with arrays of tiny wind-powered microturbines and hydro microturbines generating power as water flows through municipal drinking water systems or the outflow of municipal sewage treatment systems?  They’re real."
