All Mr.Ibbitson's argument amonts to is laissez-faire is the way to go.

If this self-sustaining, un-subsidized boon is true (and I doubt it), it's best not to lift a finger.  Why punish people for using fossil fuels (but, of course, only in 1st world  countries!) if they'll leave anyways.  It just makes Ontario's green energy stupidity all the more unnecessary and all the more stupid.

News item:  Rural Texas is a lot more thinly populated than rural Ontario, and has different wind patterns.  Nor is electricity in Texas exorbitant.  Nor has Texas, generally, any interest in signing up to Paris.

News item:  Canada isn't India.  The sun shines less here and at a lesser intensity.  Latitude, you know.

I don't believe Mr. Ibbitson's optimistic predictions will come to pass.  Paris for Canada is like a tandem bicycle - peddling hard and getting nowhere.
