Here is the beginning of a piece of news:

A group of U.S. Senators visited Brazil in August
to take a look at the country’s ethanol industry.
“It was a real eye-opener. I was just amazed what
we learned,” said Sen. Mel Martinez ( R-Fla).

What most impressed the delegation was the
choice Brazilians have at the pump. Since the
1973 oil embargo, Brazil has battled to achieve
energy independence, replacing gasoline with
ethanol, an alcohol distilled from sugarcane…

In Brazil ethanol, or ‘alcool” as it is called, costs
only $2 at the pump, compared to $4 for a gasolineethanol
blend ( Brazil no longer sells regular
unblended gasoline). And while ethanol-powered
cars consume 25% to 30% more fuel per mile than
gasoline cars, the average motorist can save about
$820 a year by switching to ethanol.
