Every time you see someone in an electric car, you think they are doing a lot for the environment. However, that's not necessarily the case when you consider all the materials and minerals used to make the car, which come from mines in China. I'm thinking in particular of coal, which is currently used for electricity generation.
When you take these factors into account, it's not clear that electric cars, right now, have a huge advantage over traditional cars. There's a big debate about that. Is this an accurate description?
