The world has gone crazy about electric cars these days, it seems. At least the wealthier part of the world. They promise to provide a more technologically advanced future, and they're widely perceived to be much more eco-friendly than any other means of transportation.

Of course, electric cars do have some issues of their own, too. These are several. The biggest one is the long time it takes to re-charge the batteries, given the current level of technologies. Then, the relatively short distance a car could run with one charging. This would eventually be solved by improving the capacity of the batteries. But, because producing the batteries takes energy, it's important to do it in an energy-efficient way, and drastically reduce the use of fossil fuels in the process. Because it's not like producing batteries for electric cars does not leave a significant carbon imprint.

This is where the above study comes, which attempts to give a broader and more detailed picture of the whole process. It was done by IVL, a Swedish institute of ecology research, by the behest of the Swedish transportation administration.
