On Electricity (Generation)
The threat isn't an existing energy shortage. The threat is how easy it would be for a serious energy shortage to occur.
Consider where we get our oil. Most of it comes from politically unstable parts of the world.
Why do you think Bush just asked to double the energy reserve? Because if something happens (and if he's doubling it, he thinks something very easily could happen)we'll be up the creek, sans paddle.
Try thinking long term sometime. It's amazing what a little perspective can do on a subject.
