Bio-fuels - not all they are cracked up to be?
I have been listening to the news in the last day or so and getting the impression that the government is now backtracking on its commitment to one of the latest renewable energy crazes, that of bio-fuels. It would now appear that certain types are more polluting than petrol.
Also, because so much land is now planted to bio-fuel crops there is a shortage in food crops. Apparently, farmers in America are getting large subsidies to grow bio-fuels, so of course they will swop over if its more profitable than growing food crops.
Save the planet, allow us to drive our gas-guzzlers, but forget to feed the people.
