Producing biofuels will further drain “the world's most valuable, irreplaceable and finite natural resource: fresh water.” ++ For example, 9,000 gal. of water are needed to make just one gal. of diesel fuel; 666 gal. are used daily to feed one person. ++ To have any effect on global energy problems, biofuels “will require much more water than the world can afford to give up.” ++ Water is too often wasted because it is free. ++ Pricing policies would encourage the development of water efficient crops and smart irrigation systems.
