Guardian: US wind farm energy up in the air over climate change, says study

The great gusting winds of the American midwest - and possibly the hopes for the most promising clean energy source - may be dying, in part because of climate change, according to a new report.

Areas of the midwest have seen a 10% decline in average wind speed over the past decade. Some places - such as Minnesota - have seen a jump in the number of days where there was no wind at all.

This study is so filled with caveats and uncertainties as to be bordering on bogus, and makes me wonder the about the funding source.  even the sensors used have come under question.  as some of us realize from the accuracy of weather reports, meteorology remains an inexact science.

gah!

I realise this may be an impossible question to answer in anything but vague terms, but is a day without wind (or with less wind) an entirely lost day anyway?

In other words, would you expect the dominant factor in how long a turbine lasted to be age or wear?

It's all about load cycles, regardless of the number of days.  Turbines in sites with strong turbulent winds do have less lifetime, which usually means replacement parts come sooner.  Still, after replacement, turbines in California have lasted over 25 years and some are still spinning.

And the study is one thing. Another is a sensationalist headline turning a 10% decline into winds "dying".
