The Clean Tech Revolution
"Today, Brazil gets more than 30% of its automobile fuels from sugar cane-based ethanol. In the United States, ethanol is nearly a 5-billion-gallon-a-year industry, on target to reach 7.5 billion gallons (about 5% of total gasoline consumption) around 2010. One of the greatest opportunities will lie in distilling fuels and creating materials from cellulosic nonfood crops such as switchgrass and jatropha." (p. 21)
