Are electric cars really so environmentally friendly?

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?

Answers:

People in the UK!!?

i get the feeling that its to make the owners feel smug for these reasons

Did he run a red light?


a. that theyre doing something 'for the planet' i.e. they're 'contributing'.

Is it illegal to use two feet while driving?


b.that they can afford the cars. i think theyre quite expensive

Why do people judge others based on the make or kind of car they drive?


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

The cheapest way to ship a book from US to Australia?


so in answer to your question

I just leased an 2007 BMW 530i. If i put in regular gasoline (instead of premium), would it damage the engine


electric cars are a failure of engineering. until they find renewable sources

Driving lessons (uk) please help?

they must still have environmental consequenses due to the elecrtical supply needed to recharge the batteries unless it was nuclear generated electrical power supply.still they must be cleaner than diesel or petrol engines.

What does it cost to have your car or truck toll now?

I think you are correct. Pollution is a by-product of virtually all manufacturing. Batteries are a hazardous waste when it is time to dispose of them.
We still have coal-fired electric utility plants in the US.

Is E85 the answer?

They can be, but you point out two very good questions about electric cars. If you could re-charge your car overnight using solar energy, that would be ideal. The biggest drawback to electric cars right now is battery technology. Batteries are still too heavy & too expensive to make electric cars really worthwhile right now. Alot of companies are working on new batteries. If that happens, we could see alo tmore elctric cars. Until then, drive a Civic and be happy :-)

Who does laughing gas (nitrous oxide)?

Sorry folks, it doesn't matter what power plants burn.
*
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:

A question about Land Rover Defenders, please help?


-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.

How many gallons of gas does an 18-wheeler hold, and what's the average MPG for a big rig?

All those cables stretching out along the roads. Keep tripping people up.

Why are stock car tachometers positioned strange?

good point a real environmentalist would have a pedal charger at home and cycle charge the batteries or just walk (i guess)
