Electric cars not 'emissions free', says watchdog
Filed under: Cars
The manufacturers of electric cars would have us believe that their vehicles are entirely emission free but they are not being entirely truthful.

An investigation by consumer watchdog Which? found that the carbon dioxide (CO2) used to generate the electricity (much of which is produced via traditional non-renewable fossil fuels) needed to power these eco-friendly cars is not a million miles away from that produced by a standard motor.
The Which? experts compared the CO2 created by charging electric cars with the emissions from the most efficient diesel cars on the market - their conclusion? "Sometimes there's not a great deal of difference."
And as the makers of conventional cars battle to cut emissions from the internal combustion engine, the gap between the two is narrowing.
As part of their research, Which? tested three of the first electric cars due to hit the UK with three "efficient" standard vehicles.
The electric Smart Fortwo was found to create the "equivalent" (based on the electricity needed to charge it) of 84g of CO2 per kilometre driven, while the diesel version emitted 103g.
Meanwhile the electrically-powered Nissan Leaf used 81g per kilometer as compared to the VW Golf 1.6 TDi Bluemotion's 108g.
But while both electric and standard motors were responsible for similar levels of CO2, the price difference is considerably wider. For example, the electric Smart Fortwo is expected to cost in the region of £21,000 as opposed to the diesel version which costs just £9,540.
The Which? report stated: "The common manufacturer claim that electric cars produce 'zero emissions' ignores the fact that most drivers use a conventional electricity supply to charge them, which has a carbon cost from burning fossil fuels."
However, electric cars still represent a much greener way to travel since they do not produce CO2 emissions from the exhaust.
Which? Car editor Richard Headland told the Daily Mail: "We applaud car makers' efforts to create greener cars - but we don't agree with their 'zero emissions' claims. Until more electricity is produced from renewable sources in the UK, the carbon footprint of driving an electric car may not be as small as owners think."

I don't 'wanna' anything. I think this sort of intrusive advertising should be stopped at source by AOL>

The comment that electric cars are a much greener way to travel ignores the facts that they use a much greater amount of energy to manufacture and the batteries last for only three years. Add the CO2 output from that and I think you will find that the diesel car is greener!

batteries last like 2 years i think and cost about 8000.00 to replace, and are full of toxic metals and plastics? (make your own mind up??)

Why aren't electric cars covered in solar cells instead of paint, then they might possibly be really 'green'

This Which report just proves what the sensible people have known for ages.
Electric cars are just another money making scam.
I am sorry but the internal combustion engine is going to be around for a while yet. And becoming more efficient all the time.

everyone seems to overlook the manufacture of the batteries for the electric cars
o.k.so there is one maybe two batteries in a conventional car but many more in these electric cars.a thought, many people run out of petrol, what would you do if you forgot to charge the electric car?

Why do we allow ourselves to be brainwashed by this rubbish? We are all given these facts, the politicians swallow it all hook, line and sinker, they suddenly become experts. Make up your own mind based on facts, not propaganda spread by the clowns that have got the country into the mess it is in today!
