It's more that there's comparatively little insolation here, unlike pretty much all of the US. If you go to one of the US cities that's incredibly far south like Seattle, you've got way more sunlight pretty much all year round.
Even down here at 57°N I'd need a solar farm the size of a football pitch to run a few lights in winter, and it would have to have the panels practically vertical because for the six hours or so the Sun is up the highest it ever gets is 9° above the horizon.
You're pretty okay for wind though, although if you're on the north-west coast it needs to be good for maybe 140-150mph sustained.
