Wind farms cannot accomplish this. And solar panels can't do it, either.

You err in thinking that a solution must be homogeneous.
Is there a potential role in out energy future for wind, solar, geothermal, tidal, heat-shifting, and biomass.
Many of these are less expensive over their lifetimes in terms of total energy produced divided by total costs that any nuclear.
We only need enough nuclear to provide the bridge, to fill the gaps these cannot.
Thorium Energy Amplifiers, a technology I have been suggesting to people since the 80s, ought to be a part of the nuclear side of the equation because they can be used to degrade high level nuclear waste while extracting its remaining energy, and can be used to destroy existing stockpiles of plutonium and highly enriched uranium which is an essential step to world nuclear disarmament.
Other nuclear technologies are in the offing as well.
Boron-11/p fusion is a distinct possibility with the Polywell, and that is getting some (not enough) funding from the US Navy.
ITER is coming along, and there have recently been advances at JET that address stabilization of the plasma and which will feed into ITER design pretty much directly.
And of course there is the nightly reminder that we have a source of He-3 only a quarter-million miles away, and also the reminder, as a particular bright satellite passes overhead, that we might have to fight a war for it.
But Solar makes a lot of sense in many places, and even without subsidies will pay for itself in many applications. And where it will strictly not pay its own way, it might still be cheaper than the provision of new power generation or distribution infrastructure by the local utility. Especially as it provides peak output on sunny summer days when cooling loads are highest.
With regards cooling costs, there is the concept of heat-shifting. If you can make ice when it is cooler, and energy rates are lower, and then use that use for cooling during the day, you can show large economies. This is done right now in Chicago.
And you can heat shift from season-to-season. The 19th century frozen water trade shows that model. You harvest ice from northern lakes and river impoundments and then store it in insulated buildings until it is needed to assist cooling in warmer weather, and transport it to where it is needed via rail.
Wind is just an obvious resource that give amazingly large gains when implemented properly, and we are closing in on optimal design for wind power. Like solar, it functions only in the correct weather, but when you average it out over a very large area, you can get a fairly consistent input. Site selection is key.
Biomass is utterly essential for those things we can never do without liquid fuel, and also for recovering value from things like scrap and garbage. Biomass can be burned directly, of course, or can be processed into liquid fuels for powering aircraft and those few terrestrial vehicles which cannot feasibly be electric.
So, as usual, MHaze, you err in thinking that knowing a little about one idea allows you to shoehorn everything into that idea. This is a common intellectual failing on those who have not studied enough; Keep studying!
