There are serious hurdles to decoupling ourselves from coal, but none of them are insurmountable. At least not hypothetically. :)

One interesting idea I've heard in regards to storing electricity is using electric cars as batteries. Granted, this would require a massive retooling of our grid and our transportation system -- not to mention the question of where we will find all the resources to make so many batteries -- but it's still interesting.

What's troubling to me is all the sensationalism surrounding nuclear, which seems to suffer from lots of near-religious objections. Nuclear is dangerous but even in the worst scenarios (like the Fukushima Daiichi plant) the damage is far less onerous than the continued operation of coal plants.

all the batteries that we have ever build combined cannot store 10 minutes of the electricity that we currently use. We need order of magnitude breakthrough with batteries first.
Usually a hydro power plant is used as a "battery". When the demand is low, the electricity produced by wind/solar power plants is used to pump the water uphill. When the demand is high, the hydro power plant releases that water to produce energy.

That works in Norway, but would it work all over the globe?
They do it in Japan, and I think they do it in Quebec. Don't quote me on the second one.

They had to have rotating power outages for a week or two in Japan after the earthquake because of the need to replenish those reserves.

Summary: Infusing Li-based batteries with the Tobacco Mosaic virus could boost their storage capacity up to 10x. There's one order of magnitude...
