"Any plant based fuel grown in soil is
subject to all kinds of vagaries - blight, drought, locust plagues"
Brazil does quite well with cane ethanol , very successful at it, for
running cars there.
Big National Geographic story on it a few years ago.
The processing plants even generate their own electricity from the fuel
they produce.
not saying it's perfect or a panacea ...just that at least that one
country has done a lot in the direction of not using fossil fuels for cars.
I believe they are a net exporter of petroleum even.
