Do Biofuels Still Have A Place In The Global Energy Mix?
Less than a decade ago, biofuels were set to take the energy world by storm. They promised a low-carbon alternative to gasoline, while advances in algae technology were taking biofuels beyond the traditional soybeans and corn. In 2015, the contrast could not be starker.
The new frontier of biofuel technology has all but disappeared off the energy agenda, while opposition to traditional biofuels has only grown. The overarching question now is whether biofuels have a place in a sustainable energy future and what role should they play?
The debate over the negative impact of ethanol and soybean-based biodiesel is not a new one. But in an era in which environmental groups are increasingly savvy and the concerns over the economic and environmental implications of climate change are increasing, opponents have a strong case to make. Of course, as with many polemic discussions, the reality is far more nuanced than what we are often led to believe.

In 2014 this translated into over 14 billion gallons over the course of the year. This staggering figure has far reaching implications for corn prices and agricultural practices. The requirement that gasoline be blended with 10% ethanol, and the hefty subsidies the industry has received over the years have kept the sector afloat.
