Electric cars cause more pollution than petrol cars

Mitsubishi’s all-electric i-MiEV, produces just as much CO2 as a mid-size car when used in Victoria.

Want to go green in Victoria? You’re almost better off driving a fire-breathing V10 Lamborghini than an all-electric Tesla Roadster, according to government figures.

Generating the electricity to recharge the Tesla, which drives the vehicle about 340 kilometres, adds the equivalent of 316 grams of CO2 to the atmosphere for each kilometre of travel, the Department of Infrastructure and Transport’s Green Vehicle Guide website shows.

That compares with 325g/km CO2 for the Lamborghini Gallardo LP 560-4, a performance-driven supercar that drinks premium unleaded fuel at the official rate of 13.7 litres per 100 kilometres.

The figure gets worse for the Gallardo when the emissions from fuel production are added, which contribute 25g/km CO2.

Victoria generates the bulk of its electricity from brown coal, which contributes greatly to the carbon footprint of power production in the state.

The surprise, though, is Mitsubishi’s all-electric i-MiEV compact hatchback, which in Victoria accounts for 185g/km CO2, or about the same as a mid-size car.

Tasmania, which sources most of its power from hydroelectricity, drops the i-MiEV’s figure to a more manageable 47g/km CO2, beating even the Toyota Prius, while the Tesla, at 81g/km CO2, just slips under the Prius’ 89g/km.

New South Wales electricity is also much cleaner than Victoria’s, with the i-MiEV producing the equivalent of 144g/km — about the same as a small car — and the Tesla 247g/km, or about the same as a high-end V6-powered Holden Commodore.

Barry, you should check your figures — the title should be the opposite Green Smack for ICE’s — production of 1ltr of fuel produces over 5kg of C02 (1 barrel of oil after production is 73lts and 371kg’s of C02. therefore 1lt of fuel is 5.082kg’s of C02)

1kWh of energy produced even from coal = 900gms of C02, and 1kWh will drive a Tesla Roadster just under 10kms with 87% efficiency (ICE at best are maybe 25% — thats important to know) — so its more like 110gms (not your 316 as quoted)

In any event, this is mute when EV’s are powered by renewables like Solar from the home — the effect is then ZERO — thats what EV owners do in Australia — no such thing as renewable petrol. The Green Smack for ICE’s

I appreciate you love your cars, and this is an automotive column, but lets get some tech savvy peeps input with accurate information to such articles otherwise they seem ill informed —

Cheers! Michael

The conclusion is bleedingly obvious. The Feds and States need to work together, tell the coal companies to shove it and convert ALL coal-fired stations to natural gas while greener alternatives are found. That is an immediate 30-40% reduction in CO2 depending on the plant. An added bonus is that we don’t need a Carbon Tax then

Cue the But I will use solar panels commentators.

The standard 1.5Kwatt, heavily taxpayer subsidised installation will not make much difference to Victorian electricity supply.Our Federal and State Governments only have token plans for renewable energy with no overall plans to phase out Brown coal consumption.They have plans to sell Victorian Brown coal to India in a 25 year contract. Any coal saved will be producing CO2 in India.

Clearly you don’t have solar panels. But thanks for commenting on something you have NFI about.

I’ve seen dodgy figures before, but these take the cake. And this is what our government are using? Now wonder they are opposed to any action that might actually see progress, their views are all bought and paid for.

Time to join the occupiers, this is a joke.
