We use oil because it is the cheapest and most transportable form of energy readily available to us. Nothing else comes close on all three criteria. The same people who oppose more drilling because it would take 10 or 20 years (the number grows with each retelling) to get the oil to market want us to implement alternative forms of energy that would take at least as long.
What do we use until then? Oil. So why not use our own and not enrich countries that hate us?
Barack Obama voted against offshore drilling. He has toed the party line. No “change” there, just strict adherence to his party’s failed policies.
