America should not become more dependent on oil  A successful development of the Pipeline would deepen the Unite States’ dependence on Oil, and undermine the drive towards renewable fuels.  Historically, consumers switch fuels not when alternatives are available, but when economic forces cause costs to rise to such a point that it becomes inefficient not to switch. This is one reason why the EU has found such success with taxes on gasoline which brought its price above 4$ a gallon long before it reached that price on the market. The result was a rush to adopt smaller and more fuel efficient cars, and to ration other energy consuming hardware.  The main result of the Keystone Pipeline will be to lower fuel costs in the short-term, under pricing electric cars and alternative fuel sources. When gas prices finally rise, as they eventually will, the United States will find itself far behind the rest of the World in renewable technology.  Given that renewable technology will be one of the major sources of economic power in the next few decades, choosing short-term savings over-long term investment seems like a bad idea.
