Could sugar cane save the planet?

For the past few months, motorists in Somerset have been taking part in an unusual experiment: filling their cars with fuel made of fermented Brazilian sugar cane. Only a handful of cars, including 10 police vehicles, can use the resultant ethanol and only five pumps – on Morrison’s forecourts – can supply it. Nevertheless, the council has high hopes. In three years it aims to have 300 cars running on bioethanol. By then, it will be made at a special plant for turning the county’s wheat surplus into biofuel.

It sounds like a dream of the future. Forget about digging up more and more oil to run the ever increasing number of cars. Just grow the fuel and relax as the problem of CO2 emissions is finally solved. If only it were so simple.
