A surprisingly high amount of biofuel is produced in Iowa, but the products that fall under this category and the ways in which they are produced spark frequent controversy and debate.
To begin, let’s break down what “biofuels” actually are. Defined by National Geographic as “plant-based solutions to the Earth’s growing energy problems“, biofuels are sourced from plant matter instead of petroleum. Gasoline and diesel are technically also biofuels, being made from decomposed and fossilized plants, but they emit massive amounts of CO2 into the atmosphere–causing a number of dangerous effects that heavily contribute towards climate change. Biofuels are more specifically made from living plant matter.
Ethanol is an example of a common biofuel produced worldwide, and Iowa is a top producer. Ethanol can be made through fermentation and a breakdown of sugars and starches, making corn an ideal component. An increase in biofuel use, theoretically, should reduce our dependence on fossil fuels.
There is some debate about the effectiveness of biofuels when taking into account everything required to harvest and process the crops needed for this form of energy, however, with many pointing out that despite its benefits, the production of ethanol leaves a large carbon footprint anyway. With Iowa being a major producer of ethanol, these arguments tend to converge on our cropland, and farmers are split on the issue, as biofuels provide some significant advantages over fossil fuels.
Setting debates aside, a common ground most debaters find themselves on is the desire to figure out a way to reduce our overall carbon footprint, and this is a journey that we will likely be on for a long, long while.
