The problem is our addiction to irresponsible (read wasteful and cheap) uses
of readily available supplies of fossil fuels.

Let's move beyond academic controversy that waste countless hours and
millions of dollars and start describing ways to implement more sustainable
solutions -- NOW.

It has been know for more than 15 years that Ethanol blended gasoline
produces slightly higher criteria pollutant emissions than other forms of
oxygenated gasoline and other alternative fuels, such as compressed or
liquefied natural gas and hydrogen-natural gas blends.

Unfortunately publicity about the transitional benefits of widespread
conversion to natural gas fuels for vehicles has withered as the ethanol and
Biodiesel advocates have taken center stage and attracted billions in
investment and subsidies. Because environmental benefits have not been
internalized into the economic analysis, it is widely perceived that less
expensive, and thus less risky, use liquid fuels in vehicles is preferable
to the difficult and expensive switch to gaseous fuels.

The economic philosophy of Keynes, who said something like "In the long-term
term we are all dead" still drives financial decision making.

But in the long term everybody will be driving vehicles that use one or more
energy carriers derived from renewable, nuclear or carbon-sequestered fossil
energy sources. Those energy carriers are as follows:

Electricity
Hydrogen
Methane
Ethanol
Biodiesel

There are many energy sources, many proven and emerging technologies and
many business strategies available today. Pick you favorites and make a more
sustainable energy future happen -- NOW. 

Carpe diem.

Subject: Ethanol may cause more smog, more deaths

Yet another controversial study to consider in the ongoing ethanol debate...

WASHINGTON - Switching from gasoline to ethanol ? touted as a green
alternative at the pump ? may create dirtier air, causing slightly more
smog-related deaths, a new study says.
