Over the years, the demand & price of corn has increased considerably. Increased price of corn has made the food industry and restaurant industries unhappy while the corn farmers feel quite glad about it. In 2007, Environmental Protection Agency (EPA) imposed a mandate that requires using a fixed amount of ethanol as additive to gasoline. This is the reason cited for the increased demand for corn. In the year 2013, the amount of ethanol produced from corn totaled to 13.8 billion gallons.
As per the current situation, the EPA has proposed a reduction in the ethanol produced. Two reasons are mainly responsible for this. Firstly, gasoline consumption has reduced over the past few years due to increased automotive fuel economy and more number of unemployed workers. While gasoline consumption has reduced, the ethanol quantity being added to gasoline remains the same at 10%. Secondly, the mandate for more amount of ethanol produced every year is another reason for it.
If you want to explore the need for biofuels and their contribution to a cleaner & healthier environment, you can take a look at the book "Renewable Energy : A Common Sense Energy Plan". Written by eminent author Brad Linscott, this book includes info that you will not find in any other biofuels books or nuclear books. Before deciding on the future requirement of biofuel, you need to go through the biofuels chapter given in this book. You can get the book from Amazon or from the site of Tate Publishers by paying a nominal price.
