by John Linder (National Corn Growers Association/Farm Journal AgWeb) … One song that stuck with me from that decade was “Everything Old Is New Again.” I find a lot of truth in the song’s message when I think about climate change and solutions like ethanol, which, coincidently, also took off in the seventies amid growing environmental concerns with gasoline. Compared with the ethanol from the seventies, or even from the nineties, today’s ethanol offers improved environmental benefits with the potential to achieve net zero emissions. President-elect Joe Biden made climate change a signature issue of his campaign, with legislative action expected in the new year. While some have singled out electric vehicles, or EVs, as a solution to reducing emissions from transportation, we know a mix of options is needed to meet this challenge. The good news is we can deploy and scale current technologies to make progress toward decarbonizing our economy today, while other technologies catch up.
