As it happens, a week ago Nicholas Rivers of the University of Ottawa published 
the best work I have seen on the subject of DST-based energy savings in Canada. 
Rivers found that in Ontario, DST reduces electricity demand 1.5% during the 
couple of weeks after the transition (he studied transitions, not year-round 
consumption). Like Havranek et al., which I cited a couple of days ago, Rivers 
hypothesizes that DST-based electricity savings is most pronounced at high 
latitudes, and notes that he does not estimate the costs of DST (e.g., due to 
increased traffic accident rates).
