Now question is: Do we want to stay on Mountain Standard Time all year, do we want to go to Mountain Daylight time?
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).
