this really is a case of somebody using statistics to try and prove their point though, it's a very slanted view on things. First of all, the notion that they use nickel and ship it around is something thats pretty universal, thats how it happens everywhere with just about every natural resource, china and taiwan are two of the leading manufacturing areas in the world and they have limited mines and wood, where do you think it comes from?
Also that whole dust to dust study of cars is totally bogus, they looked at energy costs but not where that energy comes from. Some methods are a lot more environmentally friendly then others, and as a general rule (I assume this is true in this case), the energy used to make electricity on a mass scale will cause less pollution then say, one gas guzzling SUV. They did not in any way look at actual pollution production, but only energy used in the lifetime of the vehicle and they assumed a direct correlation, or at least the people who quote the study do. They also took the cost of planning, developing the technology into consideration which is ridiculous. So R&D costs for something new is higher than the costs for something that hasn't changed much for a hundred years, and this is a surprise or in any way puts into question the positive environmental impact something like this could have?
I am not saying that a prius is the jesus of cars, and everybody should run out and get them, but this article and the study it's at least partially based on is very biased. Hybrid cars could very well be a potential problem on many fronts that haven't been explored yet, what to do with all the used batteries could be a problem. Then again fuel cells are far from perfect too While fuel cells burn clean, the problem is producing enough hydrogen to keep these cars running and right now the "best" way we have to do this is the electrolysis of water, which costs huge amounts of electricity, so it's not a totally clean technology either.
