Law mandating ethanol use

By 2009, nearly 11 billion gallons were produced, and in 2015 that figure rose to 14.8 billion gallons.The 2007 energy act goes further, requiring 36 billion gallons be made by 2022.The supply and demand in corn markets can result in volatile corn prices, which could allow prices to spike if a particular year suffers from an extended drought.High corn prices could also drive up the price for chicken, beef, pork and other animal products that are produced in confined animal feeding operations (CAFOs).The Act does say that 22 billion gallons of that total should come from cellulosic ethanol derived from products like corn stover, switchgrass and wood chips, but this method of producing ethanol currently does not exist at commercial scale.The process for cellulosic ethanol takes the feedstock material and subjects it to enzymes that convert the cellulose into sugars that can then be used to produce ethanol.To improve combustion in engines, ‘anti-knocking‘ agents have been added to fuel since the 1920s.The first antiknock agent was lead added to gasoline to boost the octane rating, but significant environmental and public health damage led to the phase out of lead additives in the 1970s.

Most motor gasoline with more than 10% fuel ethanol content is sold in the Midwest where most ethanol production capacity is located.Current EPA fuel standard volumes measure in the millions of gallons versus the billions of gallons required from standard ethanol.An increased market for corn ethanol may influence farmers to increase acreage devoted to corn over other crops.Gasoline dispensing pumps generally indicate the fuel ethanol content of the gasoline. Currently, only flex-fuel and light-duty vehicles with a model year of 2001 or newer are approved by the EPA to use E15.Flex-fuel vehicles can use any ethanol-gasoline blends up to E85.

Federal law requires that fuel ethanol contain at least 2% denaturant by volume, but the actual amount in fuel ethanol may be higher. motor gasoline occurs to meet the requirements of the 1990 Clean Air Act (RFG Fuel) and the Renewable Fuel Standard set forth in the Energy Independence and Security Act of 2007 The U. Environmental Protection Agency (EPA) administers the requirements with the Renewable Fuel Standard Program.
