A friend of mine asked me an interesting question when I told him about my hybrid. He was wondering how green the manufacturing process is. Is there any effort to use recycled materials in the cars? How far do materials travel to get to the factories? How far are the cars typically shipped to get to the dealerships? Do car manufacturers even take that sort of thing into account? My guess was no. Is there any push by consumers to make the manufacturing process greener for hybrids or just cars in general?
