Thanks for an article I can happily pass on to others.

I was surprised at the effectiveness of even the small 20km all-electric range of our plug-in Prius.  On days when we make a lot of short trips and can plug it in between trips or at destinations, we often use very little or no gasoline.  Even when we average in longer trips (Montreal-Toronto), we still average about 2.2l/100km. 

The electricity we used to use drying clothes provides about 7000km of driving per year - a cost of about $15 per month.

The newer Prius Prime would be much better.  I don't see how pure gasoline cars can remain competitive for much longer - they seem so crude and out of date.
