Ethanol vs Battery

Does a corn-ethanol vehicle beat the Tesla Roadster in lifetime CO2 emissions? — Autoblog Green

Over the vehicles' lifetimes (of 145,000 miles), Biofuels Digest says, the E85 vehicle creates 30 percent fewer CO2 emissions, and the Roadster will even put out 21 percent more CO2 than a car that uses straight gasoline...

100% coal grid, constant gas prices, lowballing Tesla's mi/kWh...

of course, what can we expect from someone who puts a acute accent on the 'e' in C.A.F.E. :wink:

I just noticed now they added battery cost in. The Volt is aiming for 150k mile durability for its battery so it wouldn't need a battery replacement. And it has a much smaller battery so it shouldn't cost the same. I guess they missed that.

And obviously they didn't mention you can still keep using the battery after the rated life cycle, it'll just have less capacity.

I guess with plug-ins now in the spot light and getting a lot of funding, we should get ready for more and more people to attack it (I believe they only started this study because they felt they were getting shafted in terms of development money, saying biofuels only got $20k).

It's funny they are complaining biofuels don't get enough funding when ethanol gets billions of dollars of subsidies every year.

Also they don't seem to realize even though loans were approved for companies like Tesla, that doesn't mean they got the money yet (as we know so far).

Looks like biofuel carbon accounting methods are once again being called into question.

The way these conflicting studies came out makes me think the biofuels people knew this latest report was coming and wanted to release some alternative data (read "smokescreen")

Biofuels Aren't Really Green | IEEE Spectrum

Pretty much says that we need two earths worth of land to do biofuel, and 6% of an
earth to do solar.

There is also a pretty cool energy calculator associated with the article.

Off topic (but might be cool to start somewhere): Deflating the Air Car ("Driving on Air" in the print version) also in the November issue.
