Server farms/data centers are being located at higher latitudes, for a couple of reasons.
One, the temperatures on balance are colder, which means it costs less to keep the mountains of electronics cool. In the right parts of the country, land is cheaper, and the population is spread out enough the noise of the cooling setup has fewer neighbors to bother.
But Solar? There is a reason solar is done primarily in warmer climates, which are warmer because the sun's energy is more easily absorbed at the lower incidence angles found closer to the equator. Unfortunately, that means the cooling costs for the electronics are higher, too. Where solar (photovoltaics) is most likely to produce electricity, it will produce heat, too, so the one works against the other, and power is used just to keep the widgets cool enough to operate.
Wind may be more reliable in some areas. I recall maybe a handful of calm days in the last year, but they do happen, even here. Even then, do you want that 'data center' running on gensets or suddenly demanding line power from other sources when the wind quits blowing? Sometimes it's warm out (90+) sometimes, it's cold (-35), but both times, people are depending on that power just to stay alive.
Data can be sent over long distances with minimal loss, and cheaply.
Electricity, not so much.
Oddly enough, states with colder temperatures, thinner populations, and the means to generate electricity via coal, natural gas, or oil, are states which produce all three more traditional forms of energy.
