The idea of turning farms into fuel plants seemed, for a time, like one of the answers to high global oil prices and supply worries. That strategy seemed to reach a high point last year when Congress mandated a fivefold increase in the use of biofuels.
As crude oil prices soar to new highs, Brazil's state-owned petroleum company Petrobras is looking beyond the windfall to place bets in the growing alternative energy market. The company does
Clearly, there is a mismatch between demand and supply of cereals. And the factors contributing to this widening gap are more than just population growth.
The us demand for corn-based ethanol could cause nutrient-pollution in the Gulf of Mexico, expanding its dead zone, say scientists. The dead zone forms in the Gulf of Mexico every summer
Advice for those trying to solve the global food crisis: do not start from here. As governments across the developing world impose export bans on staple foods, further worsening the shortages on inter

The environment minister, Sigmar Gabriel, had planned to introduce the new fuel to motorists next year. It is known as E-10, and 90% of it would consist of petrol and the rest of ethanol.

From his Cessna a mile above the southern Amazon, John Carter looks down on the destruction of the world's greatest ecological jewel. He watches men converting rain forest into cattle pastures and soybean fields with bulldozers and chains. He sees fires wiping out such gigantic swaths of jungle that scientists now debate the "savannization" of the Amazon.
