Your numbers are all very sensitive to how efficiently the electricity is used. It doesn't make much sense to discuss only supply without considering [cheaper] end-use efficiency opportunities. For what it's worth, I live in an Alberta-like climate (down to –44˚C, up to 39 days' continuous midwinter cloud) at 2200m elevation in the Colorado Rockies, but am ripening my 81st indoor passive-solar banana crop with no heating system, and it was cheaper to build that way even 40 years ago because eliminating the heating system saved more construction cost than the efficiencies that eliminated the heating system added. Nowadays it's often cost-effective to add broadly comparable superinsulation or superoutsolation to existing buildings.
