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

Since Biofuel can be made from the discarded parts of corn isn’t it cheaper to make than drilling for oil?

And if so why are we not all using biorenewable fuel because it is less damaging to the environment. My understanding is it is more powerful such that they use it to run many race cars. So what is the hold up on the technology if all it requires is a slightly altered system?
