The U.S. Navy’s Tomahawk missiles also have been running on corn since 2020. 🧐 engineering
For over a decade and a half, pumps in the U.S. have been blending gasoline with ethanol produced from corn, as it was believed that the mixture was less dangerous the gasoline itself. Now a recently published study says that the environmental impact of this blending might be worse than if only gasoline were used,In 2007, the U.S. government brought into effect the Renewable Fuel Standard that permitted a partial replacement of gasoline with biofuels, such as those made from corn.
While the U.S. Environmental Protection Agency had the right intent while effecting the Fuel Standards in 2007, it did not anticipate the sharp uptick in the adoption of corn as a commodity crop following the new legislation. Lark and Gibbs said that crop prices rose significantly after 2007. Following the Enactment of the Fuel Standards, corn prices increased by as much as 30 percent, leading to an expansion in corn cultivation.
such as those made from switchgrass or waste materials, we can focus on using a replacement fuel that is sourced in a more sustainable manner. Coincidentally, the blending mandate set by Fuel Standards expires this year, providing the Environmental Protection Agency a chance to reform its policies in the light of new data.
The study was published in the Proceedings of the National Academy of Sciences and funded in part by the National Wildlife Federation and the U.S. Department of Energy.Stay ahead with the latest science, technology and innovation news, for free:
