"Today's small wind turbines are a reliable way to cut utility bills and help mitigate global climate change. At the core of the small wind industry lies a mature, tried-and-tested technology. This growing industry also attracts a lot of start-up businesses; unfortunately many of them based on half-baked ideas or wishful thinking... Here is a list of issues to consider when shopping for a small wind system."

100% of Electric Dutch Trains Now Run on Wind Power

"Every electric train on the Dutch railways NS network now gets 100 per cent of its energy from wind energy. NS Dutch Railways has partnered with energy company Eneco to use its wind turbines to generate the energy needed to power all of its electric trains. The pair had hoped to achieve this milestone by 2018 but managed the feat as of January 1 this year."

"By combining intermittent renewable energy sources through hybrid projects, developers are taking advantage of the strengths of each."

Outlooks for Wind Power in the United States: Drivers and Trends under a 2016 Policy Environment

NREL, Dec. 2016.
http://www.nrel.gov/docs/fy17osti/67058.pdf

"Over the past decade, wind power has become one of the fastest growing sources of electricity generation in the United States. Cumulative wind capacity grew from about 9 gigawatts (GW) in 2005 to approximately 74 GW by year-end 2015. ....This trend indicates a clear increasing role for wind; however, significant variability in historical annual wind installations has occurred with year-to-year fluctuations in wind deployment strongly correlated to changes in energy policies, particularly the wind production tax credit (PTC) policy."

Looking North for Solutions [Canadian Windpower]

Wind Systems Magazine, Sept. 2016, by Jean François Nolet.

"For years, Canada’s wind-energy industry has had the potential to expand its market through exports to the United States, but it is only now — bolstered by a perfect storm of supply-and-demand drivers — that the opportunity is finally becoming concrete."

Revolution Now: The Future Arrives for Five Clean Energy Technologies – 2016 Update

U.S. Dept. of  Energy, Sept. 2016.
http://energy.gov/sites/prod/files/2016/09/f33/Revolutiona%CC%82%E2%82%ACNow%202016%20Report_2.pdf

"Decades of investments by the federal government and industry in five key clean energy technologies are making an impact today. The cost of land-based wind power, utility and distributed photovoltaic (PV) solar power, light emitting diodes (LEDs), and electric vehicles (EVs) has fallen by 41% to as high as 94% since 2008. These cost reductions have enabled widespread adoption of these technologies with deployment increasing across the board."

Energy Secretary Moniz and Interior Secretary Jewell Announce New National Offshore Wind Strategy to Drive Deployment

Energy.gov, Sept. 9, 2016.

"U.S. Secretary of Energy Ernest Moniz and U.S. Secretary of the Interior Sally Jewell today announced the publication of a collaborative strategic plan to continue accelerating the development of offshore wind energy in the United States, the National Offshore Wind Strategy: Facilitating the Development of the Offshore Wind Industry in the United States, which could help enable 86 gigawatts of offshore wind in the United States by 2050. The strategy details the current state of offshore wind in the United States, presents the actions and innovations needed to reduce deployment costs and timelines, and provides a roadmap to support the growth and success of the industry."

Optimizing Lubrication [Wind Turbines]

Wind Systems, Aug. 2016, by Jesse Dilk and Jestin Hulegaard, Klüber Lubrication.
http://www.windsystemsmag.com/article/detail/1262/optimizing-lubrication

"Since each rolling bearing in a wind turbine operates under different conditions, it often is assumed using a variety of lubricants is essential for serving all of them. For operators, this means not only added logistical efforts and expensive warehousing but also the increased risk of product mix-ups. Some newly developed greases can be used for all rolling bearings in a wind turbine."

Forecasting Wind Energy Costs and Cost Drivers: The Views of the World’s Leading Experts

Lawrence Berkeley National Lab, June 2016, LBNL-1005717.
https://emp.lbl.gov/sites/all/files/lbnl-1005717.pdf

"This report summarizes the results of an expert elicitation survey of 163 of the world’s foremost wind energy experts, aimed at better understanding future wind energy costs and potential technology advancement. We specifically sought to gain insight on the possible magnitude of future cost reductions, the sources of those reductions, and the enabling conditions needed to realize continued innovation and lower costs. In implementing what may be the largest single elicitation ever performed on an energy technology in terms of expert participation, we sought to complement other tools for evaluating cost-reduction potential, including learning curves, engineering assessments, and other means of synthesizing expert knowledge."
