Airplanes can pretty much run on any liquid or gas that burns so "alternatives" are not forever out of the question for airplanes.
Bush wants to give away public lands, our property, to private industry. We cant, nor should we really want to try and drill our way out of this. We have to try and get away from fossil fuels where other means can be used. The enviormental costs are too high, not just in Global warming but also pollution in general. We should try and pass on a cleaner world to our children.
Currently, when it comes to transportation there isnt any other fuel source out there that delivers the same bang as fossil fuels so other than efficiency gains we arent likely to see a whole lot of progress there in the near term. However when it comes to generating electricity which can be transported long distances over wires its another story. All our electricity should be produced by "green" methods. When solar or wind produces surplus electricity it should be used to create hydrogen, which can then be stored and shipped, when hydrogen is burned it produces pure water. While the production of hydrogen is not energy efficient, as a means of storing energy that would otherwise be completely wasted it makes sense.
Reducing our dependance on oil makes sense in so many ways, Enviornmentally it would reduce pollution, economically it would introduce competition into the energy market, strategically it would reduce our dependance on the products of nations who are hostile to our way of life.
I dont think the "greens" were rejoicing the fact that workers lost their jobs. I think they welcome the demise of fuel guzzling SUVS but would prefer that they kept those workers and had them produce hybrids to help get the older fuel guzzling polluters off the road faster.
The greens are most certianly more on our side than Bush and the oil industry.
