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.
