Biofuel's alliance between Brazil and US

The US government have promoted the increased use of biofuels such as ethanol as key to achieving American "energy independence." Together, Brazil and the United States produce more than 70 percent of the world's ethanol. Cooperation in developing and spreading technologies for ethanol production, setting common international standards and opening new markets for alternative fuels could pay big dividends for both economies while reducing greenhouse gas emissions.
Brazil meets 40 percent of its domestic vehicle-fuel needs through ethanol, and it exports less than 20 percent of what it produces. Brazilian ethanol, derived from sugar cane, costs one-third less to make than corn-based American ethanol does and is more environmentally friendly.
