I want to know the answer to the following question:
What act calls for 7.5 billion US gallons of biofuels to be used annually by 2012?
All the background I'm provided with is that "Nearly all the gasoline sold in the United States today is mixed with 10 percent ethanol, a mix known as E10, and motor vehicle manufacturers already produce vehicles designed to run on much higher ethanol blends.". Is that enough to answer the question?
Answer: no
