Absolutely not so. Electricity is one of the most versatile forms of energy. While it's true it is hard to store in its native state, it can be used to very efficiently do all kinds of work. That work can be applied to either create direct storage of (potential) energy, or to make other forms of energy that are easier to store.
Just a couple of currently available examples:
Pumped (water) storage. Very large amounts of potential energy can be stored in pumped storage complexes as the electricity is generated. The same pumps that are driven by electricity during the storage phase are then used as generators to convert the potential of the stored water back into electricity as it is needed. The storage medium (water) can be used over and over, never wearing out. The storage reservoirs can have recreational uses in addition to their primary purpose. This winds up being a very efficient system for storing huge amounts of electrical energy.
Another use for electricity is the electrolysis (electrical decomposition) of water, creating Hydrogen and Oxygen. This is an all natural process, and the resulting Hydrogen is an extremely efficient, very clean burning fuel. Using some more of the available electrical energy to cool and liquify the Hydrogen allows large amounts to be stored in relatively small spaces.
There are lots of ways to store or convert electrical energy, especially if that electrical energy is low cost when it is created. The wind plants would supply this relatively low cost power, thus allowing for conversion and conversion losses without sacrificing much of the initial efficiency.
More ways to store the electrical energy will certainly be developed as the need emerges.
Well, no matter what, large plants will have to be built to effectively use wind power, which again, is only reliable 35% of the time in any given location. Can you imagine the greenies giving the ok to flooding more valleys just to store wind power? Not gonna happen. And, as I understand it, energy is a zero sum game. The energy used to pump the water uphill to flood the valley equals the potential energy stored in the flooded valley. So, what problem did we solve?
Now here is an interesting twist. Let’s use wind power to generate electricity to break the water molecule into Hydrogen and Oxygen. We can then use the hydrogen in fuel cells. The exhaust from fuel cells is water vapor. Water vapor makes up 98% of so-called “green house gasses.” We’ve just added to “pollution.” So, tell me, just what problem have we solved?

I doubt very much that wind generators will be extensively used because of the coalition of the greenies and the NIMBYs. The greenies say that birds commit suicide on the twirling blades, and the NIMBYs don’t want to look at them. Once the folks figure out just how expensive those things really are, the ones that are installed will be left in place to rot.
Please don’t misunderstand. I am sure that we will be able to figure this thing out. I am just not convinced that wind power is the way to go. Hydro-electric is about used up. I don’t see any more major dams being built. Heck, there is even a movement afoot to remove some of the dams on the lower Snake River, a movement that has my tacit support, BTW. (I like whitewater. It gets my adrenaline pumping, and the flooded Snake is full of Class III and Class IV runs.)
Nuc-u-lear Power seems a viable option for power generation, as does coal. Just think of all the unit trains we will see coursing across this country if we open up the coal fields (See, there is a railroad connection ). Bury the waste, and let our grandchildren figure out a way to use the energy stored there. They will. Just as they will figure out how to harness sub-space power generation, or something else that is now considered science fiction.
In the meantime, we will have to drill for our own oil, or we slip back into a 3rd world economy. Or, we won’t be able to afford all the “green” solutions that we have found. Take your pick.
