How Can We Produce More Domestic Oil and Get Rid Of a Greenhouse Gas All At The Same Time?

Ultimately the United States will have to switch to 100% renewable energy, both for the climate's sake and for the sake of our security. In the meantime, as our vehicles continue to be be powered by fossil fuel, we continue to need more oil. According to the U.S. Department Energy there is as much as one quarter trillion barrels of oil that could be recovered using what is known as enhanced recovery of oil or EOR. EOR refers to methods like steam injection and CO2 injection. Steam or carbon dioxide is forced into a well near the one producing oil. This forces out much of the oil that would have otherwise remained behind, left in the ground for eternity.
Can CO2 Injection Help Solve Global Warming?

Since CO2 is a major greenhouse gas, scientists have proposed using CO2 that has been scrubbed from coal power plants to use in enhanced oil recovery. This in effect negates much of the CO2 that burning the recovered oil produces, but still does not solve all of the CO2 problem since there is still a net gain in CO2 output by burning oil and coal. Still, using oil and even natural gas as a motor fuel in hybrid vehicles can act as a "bridge" to cleaner, totally renewable energy powered vehicles.
In addition, using domestic oil can help the United States achieve energy security. We are often reminded not to buy "conflict diamonds" but the term "conflict oil" is never used. In fact, much of the oil that the U.S. uses comes from conflict plagued regions of the world. In some cases oil revenue has boosted the wrong factions and been more of a curse than a blessing. Using enhanced oil recovery can lessen the amount of conflict oil we purchase.
