there are major problems with ethanol and biodiesel (as with all "alternative fuels".

Ethanol and biodiesel are created from plant material, which means that large areas of land need to be set aside for growing those plants.
That means either reducing the agricultural land and turning it to growing plants for fuel (resulting in less food, thus famine) or turning pristine nature into farmland.
Both are currently happening (though the famine is at the moment prevented by increasing agricultural land by chopping down forests and increasing its output by more artificial fertiliser).

But that's only part of the problem. A study a few years ago discovered that it took more than a gallon of gasoline to produce and ship to the pump a gallon of ethanol or biodiesel. In other words, the system is at the moment counterproductive, nothing but a feelgood measure.
This is due to the vehicles and systems used to run the factories and farms (and the fueltrucks) all running on gas themselves, and those facilities usually being far from the places where the product is consumed due to the high cost of land near cities and the large amounts of land required for the production of "biofuels".
So instead of a 10 acre refinery on the outskirts of town you have a 500 acre production facility a hundred miles away that produces a tenth or so of the fuel.
As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.

What our country needs as a whole is a grassroots rebellion geared on energy change.

Edit: Hydrogen cells are also an excellent alternative.
Chavez is in Venezuela, not Brazil.
Sugarcane doesn't come from Venezuela though (oil does), it comes from Cuba (another country not very popular and for good reasons).

Ethanol btw can be used to drive an engine, but it would need to be a different engine and would have to be far more massive to produce a similar power output than does a gasoline powered engine due to the lower energy content of the product.

I've already addressed the production problems of the stuff, and the reasons why wind, solar, tidal, and hydrogen aren't viable alternatives due to their environmental impact.
And that's not even taking into account the massive areas of land that'd need to be relegated to the wind and solar farms to cover energy needs.
It's been estimated that if we covered Europe with wind turbines at their most efficient spacing and covered the ground between them with solar cells we'd meet at most about 30% of our energy needs, and that would be on a good day with plenty of wind AND sun, days which are quite rare as usually there's either sun OR wind.

several reasons. At the time it was thought to be a potentially viable alternative to gasoline in the long run (which turned out not to be the case).
It was also a political statement towards oil producing countries in the middle east that the US wasn't going to be strangled by them, that they were working on ways to reduce their dependency on foreign sources for energy.
And it was required to please the environmentalist lobby into supporting the bill, which bought some required votes in congress.

*align fingers away from palm, slap face* I feel dumb.
Now if ya like the help ya could always raise our reputation...
