What started off as one sugar mill is now 11 with two refineries producing sugar, ethanol and power.
Narendra's obsession with sweating assets and using "every piece of bagasse and drop of molasses" spurred Renuka's early move into producing ethanol and power.
It also takes biodiesel, biofuel, cellulosic ethanol, nuclear power, more drilling in ANWR.
Under the administrations of George W. Bush and Barack Obama, the federal government has tried to reinvent the automobile with ethanol and battery power.

There are only two big drivers for this legislation: power and ethanol subsidies.
Corn ethanol's low power density is inherent in all biomass, which leads us to the second of the Four Imperatives.
Farming subsidies are continually under threat, but when the federal government started subsidising ethanol production and wind power, farmers realised that renewable energy offers new streams of revenue.
Brazil is a pioneer in the use of ethanol made from sugar cane to power cars.
Matching that power output with corn ethanol would require intensive farming on more than 21, 000 square miles, an area nearly the size of West Virginia.
Pure Power processes the woody biomass to produce ethanol for fuel, xylitol for food sweetening and lignin for the production of biopolymers.
We provide subsidies for ethanol that distort global corn prices and subsidies for wind power and solar energy that pay executives of otherwise nonviable companies.
Big solar power companies, just like the cutting-edge ethanol and biofuel companies also popular with venture capitalists these days, usually need to tap the debt markets and borrow money to build large production plants.
It has not, for all the hype, taken in any great measure to alternatives such as ethanol and other biofuels or to renewables such as solar, wind and wave power.
Less than a year into office, Culver is making a serious case for Iowa--already the leading ethanol producing state in the nation--to become the leader in wind power as well.
Second, governments should not pick winners or give out extensive subsidies. (Translation: Ethanol is a bad idea, and other existing "renewables, " such as wind power, are unlikely to ever be more than a niche source.) Better to have a small carbon tax to place a price floor for competing technologies, and offer large cash prizes, similar to the X-Prize for private space flight, for specified energy breakthroughs.
So despite higher incomes and more spending power, few of them are equipped to help Cosan develop better technologies at its ethanol processing plants.
