Biofuels in Brazil

The two topics that I am currently trying to learn more about are biofuels – using crops or other plant matter for fuel – and water. Meanwhile, I ran across an article in the Christian Science Monitor: flex cars are now the most popular new car there.

Computers in flexible fuel cars adjust to whatever the fuel mixture is, from all gasoline to all ethanol. These are the pertinent figures for Brazilians:

Ethanol engines use 25 percent more ethanol per mile than gasoline. But ethanol (the alcohol produced by fermenting sugar) usually sells at somewhere between a third to half of the price of gas.

If you have something to say about biofuels, water, or other environmental topics, let me know.
