We don't build them for political reasons, otherwise we wouldn't have to store waste in rusty barrels.
I don't understand how this is an answer to what I've wrote. Please provide those sources also. Thank you.
I'm a bit tired of all these CO2 comparisons regarding electric vehicles. If we put the CO2 emissions aside, there are so many other benefits moving to EV's. Especially reduced local pollution in cities such as NOx, VOC and particulate emissions. Even if we just look at noise and easy maintenance, electric cars are clear winners. All this focus on CO2 just leads to a lot of inaccurate napkin calculations on one part…
No, modern cities desperately need good public transportation.

Simply from the weight they carry, the energy required for this. Supplying a large city is neither cheap nor easy, and requires dozens or hundreds of daily shipments from dozens or hundreds of logistics companies. The majority of these happen during off-peak hours, to reduce load on the highway network. Lithium batteries still can't approach 10% of gasoline's energy density, so gasoline is mandatory for trucks, and w…
For how people die from air pollution, you can start with https://en.wikipedia.org/wiki/Air_pollution#Mortality For Europe's special problem with diesel cars, try Googling [europe air pollution diesel]. It brings up a bunch of good news articles. Lithium batteries don't have to approach gasoline energy density to handle local deliveries. Also, these trucks don't use gasoline, they are diesel. Again, where is your sou…

> It found that heavy-duty vehicles tested in Germany and Finland emitted about 210mg NOx per kilometre driven, less than half the 500mg/km pumped out by modern diesel cars that meet the highest “Euro 6” standard. However, the buses and trucks have larger engines and burn more diesel per kilometre, meaning that cars produce 10 times more NOx per litre of fuel
That is atrocious - that a single car could pollute 4x more than a large truck or bus - and it's a side of the VW emissions scandal which never occurred to me.
How did independent emissions testing not catch this - or were OBDII outputs simply accepted as accurate? The Seattle region used to have mandatory emissions testing by an independent agency, where they probe the tailpipe. This was recently ended. Were VW cars programmed to fool this testing too?

You could try reading the Wikipedia article before asking for sources for everything. This is an internet forum not a scientific journal.
E: how is the wikipedia artikel solving the problems we already have and which resulted from the current nuclear waste storage?! I've asked that above. This whole thread results from a quasi "roses and butterflies" comment.
One thing I couldn't find in the vizzes is that Europe shares its energy grid for a large part. This means that a large portion of energy consumed in say Germany might well be produced by a nuclear plant in France. It's harder to reflect these flows and get data for it, but I assume it changes the picture.

It's not forgotten by the authorities! In the SF Bay Area the local air quality council subsidizes electric car chargers. EVs reduce the total pollution and moves what's left out of the prone-to-atmospheric-inversions Bay Area.
Isn't ozone worse than traditional pollution and the main byproduct of electrical cars? So unless we go into a draconian charge laws, will cause more harm in this regard. http://www.iop.org/news/11/april/page_50606.html

So you can't. OK. E: how is the wikipedia artikel solving the problems we already have and which resulted from the current nuclear waste storage?! I've asked that above. This whole thread results from a quasi "roses and butterflies" comment.

You are free to continue believing that nuclear power is too dangerous afterwards, it's certainly not all roses and butterflies.
Right now your comments sound extremely confrontational and rude, at least on my end of the pipe.
Electric vehicles can be charged overnight and at off-peak times, so it's reasonable to assume they use a higher-than-average share of low-carbon energy. For example, around 50% of the UK's electricity production is from low-carbon sources (renewables and nuclear). But a much higher percentage of off-peak power is low-carbon. After midnight, close to 100% of the grid is low-carbon because the gas turbines spin down w…

yes but for non trivial us of ev's you have to upgrade the grid and domestic supply which is not going to be cheap and don't for get that a lot of uk housing stock (flats older houses) does not have of street parking

In Amsterdam, the city creates an electric car parking spot (with charger) near your house if you get an electric car. This is effectively a private parking spot if you're the only electric car owner in the street, and that's incredibly valuable in a city where parking spots are hard to find.
