It looks like being a bad week for environmentalists, following Sunday's report that 'eco-friendly' reusable shopping bags aren't nearly as environmentally friendly as first thought. Now, Which? UK has found that electric cars produce as much pollution indirectly as diesel-powered cars do directly. The Daily Mail reports:
Electric cars are a lot more expensive to buy - though they are generally cheaper to run as they plug in for their power from the domestic mains, say experts at Which?
The amount of carbon dioxide - the so-called 'greenhouse gas' blamed by scientists for global warming - created to generate the electricity powering an electric car, can be just as great as that created by the internal combustion engine, they say.
The main difference is that while a conventional car's emissions come out of the vehicle's exhaust pipe, those created by an electric car are generated at the power station which supplies the electricity.
. . .
Experts at Which? compared the carbon dioxide created by charging electric cars with that emitted by the most efficient diesel models and concluded:'Sometimes there’s not a great deal of difference.'
And the gap is narrowing as 'conventional' cars up their game to cut emissions.
. . .
However, electric cars are much 'greener' than diesel cars when it comes to localised emissions, as they don’t emit toxic chemicals that degrade air quality. This is especially significant in cities, where the uptake of electric cars is predicted to be highest, says Which?
The consumer report concludes: "While we don't agree with the car makers' 'zero emissions' claims, we can't knock their efforts to create greener cars."

I have no problem with efforts to reduce pollution, protect and safeguard the environment, and generally live responsibly. However, when so many of the efforts of environmentalists turn out to be nothing more than a panacea, or far less 'productively green' than they maintain, they discredit themselves. When will they learn this, and stop exaggerating?
