End foreign oil dependency in 15 years

What would it take?

As a $150 million dollar natural gas for transportation research bill works its way through Congress, I can't help but wonder, could America end foreign oil dependency with its own resources?

Could America draw a line in the sand and determine to be foreign oil free within 10, 15, or 20 years using some combination of natural gas, biofuels, batteries and whatever other tools are available today?
