My solution

"While I agree that diesel technology offers important gains in fuel efficiency and can be a good buy today, diesel technology simply doesn't compare to the potential of hybrid technology. With a limited number of tax credits available, and a Congress that refuses to address fuel efficiency - even in the midst of oil wars in Iraq and oil-driven terrorism - technology offers the only hope for change"(soultek.com). Because of this situation my solution for this problem is to only give the clean vehicle tax credit to advanced technologies that will reduce our dependence on foreign oil.
