The Ethanol Boondoggle
There are more than 250 million cars and light trucks that run on gasoline on the roads in the U.S. Every time a driver of one of those cars stops for fuel, what they pump into their tank is, by law, about 90% gasoline and 10% ethanol.
Ethanol is made primarily by grinding corn and then fermenting it. Corn is the largest crop in the U.S. Each year farmers plant roughly 90 million acres in corn–growing almost 14 billion bushels. Thirty percent of the U.S. corn crop goes into making ethanol for fueling vehicles.
In a sense, this is a form of solar power. Through photosynthesis the corn plant captures the sun’s energy and turns it into corn. However, it’s a ridiculously inefficient way to capture the sun’s energy for our use in transportation.
