According to various sources across the internet, Americans consume approximately 3.7 billion barrels of oil per year. With a little math we see that's around 10.1 million everyday. If oil were at $40 per barrel, this comes out to $148 billion oil consumed every year. Obama's new regulations were designed to, 'save 2 million barrels of oil per day'. This works out to 8.1 million barrels per day, or about 3.0 billion barrels consumed per year. If oil is at $40 per barrel this is about $120 billion per year.
