I do not think anyone is suggesting a pure solar solution.

  Your reply to me quite explicitly suggested that countries in far northern latitudes just build a proportionally larger array: > That only really matters if there is some constraint preventing you from building a proportionally larger array at the northern latitudes.

    I was replying to the assertion that the difference in power density at different latitudes was a deal breaker.

      It absolutely can be. Solar would even be harder hit in a place like Alaska, with the dual whammy of very cloudy and overcast for 9-10 months, and then so far north that the sun just barely sits on the horizon, which makes gathering sunlight very hard (very directional, 60deg angle panel, limited positioning). Works fine in summer of course, that's just a 2mo or so window.
