This could make sense in Arizona not Seattle. You would have to build more solar farms in Arizona.

Seattle is already mostly hydro, so building solar there would be a bit silly

Boston, NYC, Cleveland, Pittsburgh, Cleveland, Buffalo, Anchorage, Portland, Rochester, Syracuse, Erie, etc.

Take your pick. There are a ton of American cities where solar does not work like how you imagine

You do know that electricity, at least im countries with a power grid actually deserving that name, so maybe not the US, can be transmitted over quite long ditsances?

If I go to https://model.energy/ and ask it to find the optimal renewable + storage solution to provide a constant power output in New York state, the solution includes plenty of solar (and comes in cheaper than nuclear likely would). It also includes hydrogen though, so it would likely make sense to make some of that hydrogen elsewhere and send it to NY by pipeline.

It works just fine in Seattle - I speak from personal experience! Rooftop solar is popular here. Direct sunlight is not a requirement; PV works fine in overcast conditions, and cooler temperatures offer an efficiency advantage.
