The world needs a new source of energy, an unspillable source.

If hybrid cars are part oil/part electric, aren’t we using up our coal supply?

I was thinking about it, since hybrid cars are 1/2 oil 1/2 electric…..or whatever. I am wondering if hybrids are getting that electricity from coal, and if so, how much more is the electric bill? Because I’m starting to think that it might not save as much money as we think, and is just solving the problem with another non-renewable resource.
