Nuclear is one option, but I am not so sure it's the only one. For
example, Denmark right now generates 15% of their electricity with
wind factories.

I also think hydrogen is expensive to manufacture, was not aware that
ethanol also is.
I think that Brazil has cheap ethanol manufacturing plants from sugar
cane (and corn? not sure).

The real cure is Hydrogen

Providing electricity used to make it is generated by a source using renewable
energy.

It takes 4 to 10 times as much energy to make hydrogen than the resulting
hydrogen provides.

Ethanol has the same negative efficiency problem.

For the long term, only nuclear powered electricity generating plants will
provide most of the necessary energy for direct and (hydrogen making) indirect
uses.

Carlo: Nuclear is one option, but I am not so sure it's the only one. For

factories.

Of course, wind and solar, which are true renewable sources of energy, should
be used wherever they are feasible. But, NIMBYs aside, the resulting
electricity cannot power reciprocating engines. Hydrogen can, but it takes lots
of energy to make it. The only feasible way is to use electricity -- the
electrolysis method. But then, again, it would take a lot of electrical energy.
Thus the only source of seemingly unlimited electricity is from a breeder
reactor. Even for a conventional reactor there is something like 500 year's
worth of uranium available. But the breeder would take care of the waste
problem, too.

The electrolysis method, which is certainly better than the negative result of
converting methane, requires water, another commodity that is getting scare.
There is, in Florida I believe, an experimental site that is mating a
desalinating plant with a nuke power plant. The possibilities there seem
endless. Between sea water and nuclear energy, all the water and energy needs
of the world could be fulfilled.

CB,

This is due to Brazil's being an Oil Poor Country with Cheap Farm
Labor Costs and certain Government Policies related to the Production
of Ethanol and a Petro Mixture of 76% Gas and 24% Ethanol.
NOTE: India is developing a major Ethanol Fuel Program.

* Brazilian Ethanol is three times cheaper than U.S. Ethanol,
about 60 cents a Gallon compared with today's American price
of $1.80 a Gallon.
* Brazil has the Ethanol. It is the world leader in Sugar Production,
Ethanol Production and Ethanol Exports.
- In 2003, Brazil Harvested 350 Million Metric Tons of Cane.
- Produced 3.6 Billion Gallons of Ethanol.
- Owned 50 Percent of the Global Ethanol Export Market.

In Brazil, ALL of the Automotive Fuel sold 'contains' "Ethanol".
ALCOOL= http://www.ne-ethanol.org/piaui2.htm
In fact, Brazilian motorists can choose from two different fuels.
One contains about 22% ethanol blended with gasoline.
The other is 100% pure ethanol known as "ALCOOL".
Engines can be designed to run on 100% ethanol.
