It's noteworthy that 90% of energy used in the Netherlands is fossil fuels[1] (as of 2013, anyway).
This means electric cars will emit GHGs comparable to a 40-50mpg gasoline-powered car.
Hopefully they do some major work to clean up their grid electricity.
Electric cars are a necessary step to reducing GHG emissions, but without a clean grid they are pretty pointless.
