Ethanol from Corn Much Better than Expected
Al Fin —
... ratios ranged from 10:1 to 13:1 but could be increased to 19:1 if farmers adopted high-yield progressive crop and soil management practices, according to the study. Using advanced closed-loop ethanol production technology with anaerobic digestion reduced GHG emissions by 67% and increased the net energy ratio to 2.2, from 1.5 to 1.8 for the most common systems. These numbers are much better than the 1.5:1 so often seen and discounted to below 1:1 by non expert pundits. _NewEnergyAnd Fuel ...

Next Big Future —
New Energy And Fuel reports on a new study which says that previous studies that tarred ethanol as an environmental villain were flawed because they looked at outdated corn and ethanol production techniques. The more modern ethanol plants – which account for about 60% of U.S. production and will account for 75% by the end of 2009 – have become a lot more efficient at growing and harvesting corn and turning it into alternative fuel. ...
