Not really a sterotype at all, more like a missed opportunity for the last 50 years by Albertans themselves.  Mountains followed by a plain of land makes great wind.  If Alberta is rich in anything, it's wind.  Only now have they looked around and noticed though.  And not locals either, just multinationals.  

Also our other oil rich province, Newfoundland, is also rich in wind and the #1 source in Canada.  Both would surpass Denmark who make about $2 billion a year in wind but neither is used.  Alberta in the West and Nfld in the East would bookend the country and help everyone.

But Alberta will be just as much in a sorry state post-anything.  With gas dwindling, the tar sands will dwindle with it.  Only then will Albertans see what's left, look around and notice that they've turned their province into a gigantic wasteland.  

At that point I wouldn't be surprised if the ranchers take back their land from the windmills and make it a local power source, away from the multinationals.  Too far fetched?  Given all the (free) water used to wash out the tar sands, when the farmers are in a drought no less, the times of Alberta are looking quite unstable in a peak oil view.

potential is high though for Alberta to transform out of the oil patch if they use their money now for alternative fuel investments.  This is what the multinationals are doing now, in spite of Alberta's view of itself.  So the sterotype mentioned is largely self made.

If the post-oil world is in deep depression, or worldwide currency collapse, the money would be lost so best use it now.  

Once the oil goes though, what would Alberta's relationship be with the rest of Canada?  The ecological disaster that is the tarsands will be impossible to clean up post-oil.  There are few railways and cities are far apart.  

Tough times ahead but not without potential.
