We do need all three.
But drilling is actually the shortest-term and cheapest (with today's technology) solution. The five years cited for offshore drilling to have an impact is still a shorter time frame than any other alternative. And some effect will be felt sooner. Much has been made of the assertion that we are the only developed country not to have signed on to Kyoto; we are also the only developed country that restricts offshore drilling to the extent that we do. Many countries that are perceived as way more environmentally conscious than we are (e.g., New Zealand, Norway) have no problem permitting offshore drilling. But then again, they have a more consensus-building approach to environmental problems than our adversarial, command-and-control model.
Increased use of ethanol will require us to find additional sources of supply. That makes it a short-to-medium term solution, with some improvement annually but probably 10 years to really have significant impact. Continuing to subsidize inefficient corn-based ethanol is a loser. Also medium term, we need to look at biodiesel. And longer term we need to develop other biological alternatives (switchgrass and cellulose ethanol, biodiesel from multiple sources).
We need to convert from fossil fuel to electricity for primary movers of more automobiles, trains, and rapid transit. For that to be viable, we need significant increases in electricity supply. Nuclear, solar, and wind need to pick up a lot of that burden in the medium term.
Oil shale and coal liquifaction/gasification will enable us to use domestic resources to replace some oil imports. Moving to more nuclear, wind, and solar for electricity will free up more coal for these purposes.
Long term, we need a conscious policy to wean us from our dependency on oil, and particularly foreign oil. The numbers aren't there to indicate that we can get totally off oil. But if we develop alternatives aggressively, and if we get back into the business of developing our domestic oil, shale, and coal reserves, we can get to the point that we can significantly reduce our environmental damage while becoming a net exporter of energy. That would pretty effectively address the economic, envirionmental, and national security problems we currently face.
But there is no free lunch. It took Brasil 35 years, with an across-the-board national commitment. I think that time frame is reasonable for us, if we muster a similar level of commitment. If we had developed Brasil's level of commitment 35 years ago, we'd be there today. That's a reason not to delay one microsecond.
