Drilling for more wont do much. OPEC/arabs decide the price, they're making the money, they'll continue making money.
What we need is to fight against the oil industry for patenting all the alternatives that we could have been using 10+ years ago, and start developing alternatives that they cannot patent, for whatever reason we can find (loophole in patent law or something). It's all a big money game, we need to completely break loose of oil dependency for energy. The technology is there, we just have to put effort and use it. Sure it may cost more at first but eventually it will be cheaper.
Though until patent law is changed to disallow patenting stuff to never use it, I doubt we have much hope in seeing alternatives completely replace gas vehicles, sadly. Some guy in his garage comes up with something, the minute it goes public, the oil industry just patents it, the guy is probably shot, his prototype/plans destroyed, and it's never to be heard of again.
