I don't know about the carbon footprint but the brown footprint in the grass where I dump it from my chain saws, weed eaters , tractor & portable generator is certainly growing bigger.
Most of us learned the hard way that you just cant leave E10 in power tools for more than a month and expect them to run the next time you try to use them.
That $10 per 1/2 pint blue additive can make E10 gas last up to 3 months in old all steel tractors but is undependable in the new small power equipment with plastic tanks & fuel lines so its much safer to just dump any left over fuel on the ground after each use.
This may not be environmentally friendly but everyone I know does it because its a lot cheaper than buying a new chainsaw or weed eater 2 or 3 times a year after yanking their arm out of joint trying to start a totally dead tool.
Incidentally the old leaded gas had a guaranteed 2 year tank life, Thats why they still make low lead 100 for airplanes.
An interesting article is attached. The more so because it is from the UK Guardian - a UK newspaper slightly to the political left of Karl Marx.
The main problems are that it takes land to grow so it displaced food production. This does not affect the Americas or the Europes of this world but at the end of the food chain there is not enough food left to feed the hungry. It is not as good as gasoline in several ways. It produces less energy per gallon, for instance. It has encouraged deforestation in countries like Brasil so that they can grow more plants to produce ethanol.
Probably only slightly less than gasoline from "tar sands." But, even if it were zero, 10% ethanol in gasoline would reduce carbon dioxide emissions no more than making cars that get 10% better fuel economy. Like global warming denialism, geoengineering and the Alberta hating anti-Keystone movement
Depends on where you get your ethanol. In Brazil, with an integrated system for sugar cane production, and energy for the production supplied from sjugar cane waste, you can get to near zero net carbon. In the U.S>, with production costs heavily inflenced by petroleum based fuels, it's higher than fossil-fuel based gasoline.
It seems to be a fad on Y Answers to blame "greenies" for the disasters of corn ethanol, forgetting that corn-based ethanol production became a federal program due to a perceived overdependence on foreign oil - and continues to be mandated due to agribusiness lobbying.
I no my response might not be popular. But in the winter time I don't add gasline antifreeze type products anymore. Alcohol does burn cooler than gas in the summer. But another set back is it's less effective with small amounts. Pure alcohol motors need a very rich mixture.
Google "net energy." Although if you are as "educated" as Raisin Cain, you may have to learn what "net" means first.
