Ethanol
As a small business owner, you
may have a delivery service, or a company fleet or
you may want a more efficient personal vehicle. For
any of these reasons, take the time to read about
ethanol and its potential as an alternative fuel.During the State of the Union
address, January 24, 2007, President George W. Bush
discussed fuel consumption in the US and mentioned
alternative fuel sources to gasoline including
ethanol. He discussed ways to produce ethanol from
wood chips, grasses, agricultural wastes and other
biomasses. Ethanol from these products is called
Cellulosic ethanol. Ethanol is also known as ethyl
alcohol, or grain alcohol. President Bush’s goal is
to grow the use of alternative fuels such as ethanol
to 35 billion gallons by 2017. According to the
Washington, D.C.-based Renewable Fuels Association,
the nation produced an estimated 4.9 billion gallons
of ethanol in 2006.Currently there is a miss conception that if you
want to have a green vehicle you need to give up on
performance. Because ethanol has a high octane
number this misconception is false.Check out the
specific
Performance Rating of Ethanol.
Today the world is dependent on energy to power
growth. As a small business owner, your choice of
energy usage can determine future availability of
natural energy resources and prevent adverse
environmental effects. Using energy efficiently and
considering alternative fuel sources provides a way
to conserve energy and improve quality of life.
Research into and use of renewable energy sources
like Sun, wind, geothermal, hydrogen, ocean,
bio-mass power offer more choices as energy sources.
Solar energy power is the focus of this newsletter
and may be one way for small businesses to become
more energy efficient.

What is Ethanol?
Ethanol is being produced domestically in the US
mainly from corn. In Brazil ethanol is made from
sugar cane, it is produced at low cost without any
subsidies and at a very competitive price to petrol.
In Spain ethanol is made from grain. Below is the
table which shows ethanol yield in gallons from each
crop. Different crops yield varying amounts of
ethanol to be used for fuel. As you can see
the US’s current source for ethanol may not be the
best source for ethanol.

Ethanol
Blends E85 and E10
E10 is a blend of 10% ethanol and 90% gasoline, many
car manufactures allow use of E10 in their cars.
Some car manufacturers even recommend use of E10
because it adds 2-3 octane numbers to the fuel,
which also helps to keep the engine clean. By using
E10 in your car, it is possible to reduce use of
gasoline up to 10%. We recommend that you check with
your car manufacture to make sure that your car can
use E10. [More
Information]
E85 is a blend of 85% of ethanol and 15% of
gasoline. Only FFV (Flexible Fuel Vehicles) can run
on the E85. Currently there are close to 3 million
FFVs on the road. You can consult your owners
manual to see if your car can run on E85 blend.
The FFVs have logos indicating FFV or E85 capable
on your car or fuel. You can verify that your
vehicle can run on E85 by checking your car
manufacturer [Check].
Although E85, a mixture of 85 percent ethanol and 15
percent gasoline, has not yet found widespread use,
the nation is hungry for ethanol as an additive in
regular gasoline. If you currently have a
vehicle which can run on E85 and you can find gas
station with E85 [Search

Ethanol
and Clean Air
Below is the table which shows the
emissions of the vehicles which run on two ethanol
fuels one names E85 and the other names E10. The
table compares these two ethanol fuels with gasoline
with respect to potential air pollutants.

Some
additional facts about ethanol clean air facts
*The use of
E10 reduces greenhouse gas formation by 12-19%
compared to conventional gasoline.
*In 2004
ethanol use in the U.S. reduced CO2 equivalent
greenhouse gas emissions by approximately 7 million
tons, equivalent to removing more than 1 million
cars from the road.

Future Biofuels
Ethanol is alternative
fuel that can be found today, but ethanol is more of
the first generation of biofuels. Two giants BP and
DuPont announced partnership for development of
advanced biofuels. BP can also be considered a
leader in the biofuel developments [More
Info]
In fact DuPont was
visited by President Bush day after his State of the
Union [
Report]. DuPont also told President Bush about
their latest development in biobutanol, next
genereration biofuel which has lower vapor pressure,
more tolerant to water, it can use current gasoline
supply and distribution centers. Biobuthanol can be
produced at current ethanol producing facilities.
Biobuthanol also does
not require any upgrades to the car, unlike ethanol.
It can replace gasoline up to 100%, not just 85%
like ethanol [More]
“Developing
biobutanol, which has properties that are closer to
gasoline, will help to accelerate the adoption of
biofuels in the transportation fuels industry,” said
John Ranieri, DuPont Biofuels vice president and
general manager.
