New energy efficient cars cost energy to produce. What is that when compared to the cost to run an old car.?

Question

Not buying new would seem to make sense, as all manufactured products cost energy to make. The energy cost displayed on a product would be a useful guide.

Answer 1

I suppose it'd depend on how much the car is used. if  you don't drive often, it'd be a big waste, to melt down an old car.   I think drivetrain parts should have standardised mounting arrangements. that way cars would be a lot less "disposable" and planned obsolescent.  for example, if all "small 4cylinder engines " were required to fit  into a "small 4 cylinder" car, then you could just upgrade the engine.  And it'd make

engines  cheaper,too - if you could buy from whatever manufactorer was offering the best deal.

      This is not at all impractical, but don't expect car makers to do it voluntarily.

Answer 3

It's sort of like the clothes dimlemma. For instance, organic hemp clothing still takes time to make when I could have just bought vintage, gently worn clothes. That might be more green.

A benefit to buying a new, energy efficient car would be that we'd cut down energy consumption. Not driving a car is really the pinnacle, selling cars will be around for a while so they might as well be as efficient as possible.

Answer 4

My 17 year old truck  gets better gas mileage than than any truck  I can find now.   They don't even make them of simmilar size any more.   I'll drive it until there isn't a frame left for me to sit on.
