MPD, that is a bad way to think about it. Sure, it's not a magic wand. Obama is not a wizard. We'll still be using oil for many years to come. But having alternatives to oil makes it a much better market when it comes to shopping for energy. And staring now to get off the oil is better than starting when it's too late.
And as Wolf points out, the less we use fossil fuels the better. It's time to get over the old way of thinking, and realize we have to do something now.
