First I've heard about the statoil thing. Maxol have been quite slow about the roll-out.
I've been thinking a bit more about the environmental benefits aswell and to be honest I've grown a lot more cynical after crunching the numbers. In order to generate the "environmentally friendly" ethanol, cows feed on grass. The milk they produce is then processed. A by-product of this is then converted into alcohol in a multi-stage process, which by its nature is quite energy intensive.
In addition if you add in the fact that cows contribute much more to greenhouse gases per day than your average car, I have begun to wonder whether there really is an actual environmental benefit after all, and whether the reverse might actually be the case?
