Say It Ain't So, It's Not What I Want To Hear

Two articles. The first one links an earlier article.

First, the more recent article:
I have written before about the disappointment inherent in batteries.
Now I have another personal example. Just when I had decided that my batteries were in their prime, crash.
In our forced migration from fossil fuels over the coming century, large scale implementations of solar and/or wind are likely to transpire only in connection to energy storage solutions. With storage comes headaches, even for technologies as mature as lead-acid. Batteries will fail, and seldom at convenient times.
I liken my recent experience to driving a car without a gas gauge. How tolerable will this situation be to our demanding society? Big adjustments ahead…
Now, the author's earlier article, battery performance deficit disorder:
Don’t get me wrong: even though I dwell on the shortcomings of batteries in this post, I still hold a net positive view. When it’s dark at my house, my refrigerator, television, computers, and internet goodies are all powered by stored sunlight in lead-acid batteries. My laptop battery gets me through many a bus ride and an occasional airplane ride. Batteries really do work, and provide value. Moreover, electric cars are more than a notion or fantasy: they are actually on the road getting people where they want to go.  Despite their lackluster performance next to fossil fuel storage, batteries still beat the pants off of mechanical or gravitational storage.
And even though I might appear to be picking on the Chevy Volt by highlighting its deficiencies, I actually rather like the design point (electric vs. gasoline range hits the sweet spot, in my view). In fact, I was half way to buying one. By half way, I mean that if the price were cut in half, I would surely have one now.
The real point is that batteries fall pathetically short of our customary fossil fuel energy storage medium. When we wake up to a declining global availability of petroleum, we won’t just switch over to electric cars. We may not be able to collectively afford such a transition, given the huge up-front costs in both money and energy. Where will the prosperity come from? If oil shortages drive recession in the usual fashion, expensive options may be off the table.
