yay!! good thats wat i put too...JamesTockuss said:I agree. I think the question was more looking at the fact that Ethanol is not in fact carbon neutral, as you need to expend so much energy when you are producing ethanol from cellulose. And then I guess you had to talk about whether or not it was good for fighting against global warming - which it is, because unlike petrol the CO2 that it expels it absorbed by plants, which are used to make ethanol - wheras petrol is from petroleum - and thus it minimises global warming
i put in a photosynthesis reaction to show where co2 goes... is that rite?
