I was talking to somebody about electric and hybrid cars recently. They told me that, over the life cycle of the car, hybrid cars (e.g. Toyota Prius)are actually worse for the environment than regular petrol/diesel cars!
Independent tests suggest that hybrid cars can pump out up to 56 per cent more carbon dioxide than the manufacturers claim, and that their fuel economy is (in some cases) comparable to a standard diesel car.[The Times]
I also heard that the batteries used in electric and hybrid cars are damaging to the environment.
Does anyone know if this is true? And what are the alternatives? How does Biofuel compare? And whatever happened to Ethanol cars? (I remember that Ford used to sell an ethanol-powered car in Brazil, because ethanol could be cheaply produced from the crops over there)
And has anyone actually tried running their car off chip fat?
