Energy independence is an admirable goal, but considering how energy resources (for current technologies) are distributed throughout the world, I'm not sure how it can realistically be achieved. That said, we can do MUCH more, but for now we have to lean on oil while we push for new technologies. Energy independence means we'll have to make full use of the oil resources available to us and that will mean exploring and drilling in areas where the oil is, building more refineries, and be willing to lean on Canada as a resource for their oil sands. One of the things that makes importing oil so appealing is that so many of the messy, ugly production facilities are not in anybody's backyard here.
One thing people are leaning on these days is alternative fuels, such as ethanol and other bio-fuels. Unfortunately, while it is a step foward, there are limitations and liabilities here as well. All these fuels take a fair bit of energy to produce and the production requires massive amounts of water. There's also the fact that in the case of ethanol we're using a food resource and any bio-fuel is using a commodity that doesn't exist in sufficient quantities to do more than put a dent in oil consumption.
Here's an interesting article I came across about ethanol production:
