When Obama says " Last year, we relied less on foreign oil, than in any of the past sixteen years" he is using persuasion. He is persuading the listener by appealing to their sense of being independent from having to get oil from some of the foreign countries that we were at war with. When he states "A strategy that's cleaner" he is appeasing the people who are environmentalists and who want to do what they can for the planet. He also manages to intrigue the common working man by stating that the country will be "full of new jobs."
