What are you talking about? In the US ethanol production is up 20+% over the last ten years. https://www.eia.gov/todayinenergy/detail.php?id=32152 https://www.eia.gov/todayinenergy/detail.php?id=32152 Corn ethanol is not a very good way to reduce co2 emissions. It only yields about 1.5 units of energy per unit of energy invested vs 7 for Brazilian sugar cane ethanol. In the US it's a farm subsidy program ( in Germany their big corn subsidy is turning it into methane). The reason you think it disappeared is that everyone now realizes it's justifications don't make sense but farm states are too important to take a subsidy away from.
