Is the Prius as Environmentally as it sounds
Hi Guys,
Our Quarterly motoring club magazine has arrived, and they have a long article discussing rising fuel prices, hybrids, hydrogen, LPG and CNG.
What they basically did in the article was rate the cost of a variety of cars per KM over the life of the car. This included the cost of manufacturing, fuel, servicing, maintenance and then disposal.
The figures they came up with were suprising.
Cars like a Toyota Yaris or a Honda Jazz and Golf TDI were rated at about $2.20 per km for the life the car.
A Larger car like a Passat, Falcon and Commodore were rated at about $2.90 per km
Where it go screwy and I could beleive it, was that at Range Rover was rated at about $3.50 per km (11mpg)
AND, the Prius was rated at $3.80 per km
What the point of the article was, was that car companies need to keep exploring the hydrogen option, as once you take into account the environmental as well as the manufacturing cost of 2 - 4 sets of batteries in a Hybrid its actually worse for the environment over the same time frame as driving a Large SUV.
I was gobsmacked.
Then I realized that what they meant was:
It takes just as much energy/resources/pollution to manufacture/maintain the batteries/generators etc in a hybrid as it does to drive an big SUV. IE the extra environmental cost in the manufacturing/maintainance is the same as the environmental cost of using the fuel.
In short, they're suggesting that Hybrids are a stop gap measure but over the lifecycle of the car are no better for the environment than an SUV. Bring on Hydrogen I say
