The electricity has to be generated somewhere doesn't it? And making batteries is really bad for the environment too, so are they are really such a good thing, or does it just make the owners feel better, or even a bit smug?
a. that theyre doing something 'for the planet' i.e. they're 'contributing'.
b.that they can afford the cars. i think theyre quite expensive
and yes. generating electricity is very harmful. depending on where they get it from. if theyre burning crude oil for it then yes. but if its from wind farms or water turbines then its ok. however it is unlikely that the electricity is from either of these sources as they make up less than 5% of the worlds electricity sources
so in answer to your question
electric cars are a failure of engineering. until they find renewable sources
We still have coal-fired electric utility plants in the US.
Electric cars produce much less pollution than gas cars, because of the greater efficiency of electric drive (electric motor, 95% efficient, versus gas engine, 25% efficient.) Delivering energy by wire to electric cars (95% efficient) is also much, much more efficient than trucking gas to thousands of service stations. And fossil fuels, when burned in large powerplants, burn far more efficiently (up to 85% efficient in newer plants) than they do in your car.
The proof of all this is right in the fuel prices. Gasoline costs at least 10 cents per mile. Electric cars drive around for only a penny or two per mile. The difference comes from efficiency. Much greater efficiency = much less pollution.
Believe it or not, your gas car runs on electricity! It's true, large amounts of electricity are used to refine gasoline. Gasoline makes pollution during refining, it makes pollution when it's being delivered to gas stations, and it makes pollution when you use it. Anything else is a huge improvement.
You can't criticize batteries based on 30-year old technology. Modern EV batteries are not considered an environmental hazard by the EPA. Spent li-Ion batteries have the lithium in harmless salt form (like the sodium is in table salt.) Plus, new li-ion battery designs have very long lifetimes (10 to 20 years) and are fully recyclable.
But if you want to talk about real environmental hazards, try used motor oil and coolant, neither of which are used or wasted by EVs.
Since nobody answering here seems to know what a modern electric vehicle is, here's one:
The Phoenix electric pickup truck - with Altairnano li-ion batteries, can:
-Travel up to 250 miles per charge
-Carry 5 passengers plus cargo at 95mph.
-Charges batteries in as little as TEN MINUTES.
-Has batteries that last 250,000 miles (never need replacement.)
Yes, it is a real car - being manufactured right now for fleet customers.
