Science magazine declares ethanol worse for the Earth than fossil fuels - Autoblog
I never did think that using a food product to create an alternative fuel would be a good idea. Now using the biomass that we already generate to create fuels is a good idea if it can be done without releasing tons of carbon in the conversion process.
I know they have the technology and are currently building a plant in the Orlando, FL area that can convert just about any biomass waste into biodiesel without a lot of energy input into the system. We need more solutions like that and algae growth to make into fuels, not growing crops from scratch.
The end of the ethanol boom? - Feb. 28, 2008
Consumers not impressed?
Gas with ethanol getting the cold shoulder - AutoblogGreen
Ethanol takes a first big hit to the solarplexes.
Another effect of ethanol was the dissolving of built in fiberglass fuel tanks in boats. This clogged fuel systems, ruined engines, and cost thousands to cut out and replace the failing tanks. Also, water absorption of ethanol leading to phase separation causing corrosion in metal fuel tanks. Great stuff.
Study: Electric cars may be more efficient than ethanol
May be more efficient?
I'd say there is no "may" about it.
What toxic metals are used in lithium battery manufacturing, and do they get released into the environment? I'll be there is more toxic metal, (lead), in the single starting battery of any ICE, including ethanol powered, than in a whole EV pack of lithium.
If anyone else has trouble making the link work as I did this one seems to be better http://www.mercurynews.com/breakingnews/ci_12319686?source=rss
To add to JRP3's observation.
So which produces more electricity? An acre of switchgrass, or an acre of solar power? Is it even close?
Don't forget about Martin's slides over here:

Resurrecting an old thread...
Good to see that the U.S. has, after thirty years, eliminated the direct federal subsidy for ethanol. NYTimes article here.
Lest we think that the federal government isn't tilting the field towards ethanol still, however, the EPA also released its new Renewable Fuels Standards, which requires 15.2 billion gallons of the nation's fuels to be renewable -- primarily corn-based ethanol. So, ethanol is still getting a boost that it wouldn't in a unrestricted marketplace.
