Efforts to find affordable alternatives to current vehicle fuel choices,
biodiesel has suddenly become one of the leading replacements
Biodiesel
is considered a renewable eco-friendly resource derived from vegetable oil or
animal fats. Once the vegetable oil or animal fat is processed, it becomes a
combustible material, like the petroleum-based diesel currently used today in
many vehicles. In fact, it is used daily around the world, and is already
rapidly becoming the main stay of a lot of family budgets, with ever increasing
popularity.
Biodiesel can and is being produced from rapeseed, soybeans,
algae, palm oil, hemp, lard, mustard seed-in fact, any vegetable oil source, and
yes, even waste vegetable oil, fish oil and animal fats. In fact, the August
2005 edition of National Geographic reported one biodiesel user who got his
waste vegetable oil free from a local potato chip shop and spent eight dollars a
month to turn it into biodiesel, which as we know is common practice now in many
places.
Some of the advantages of biodiesel include:
* Biodiesel
is an excellent way to use the vegetable oil and animal fats produced today,
solving the hugely potential problem of waste products otherwise disposed of
badly and the past problems that caused our environment.
* Biodiesel is
biodegradable on land or in water, so naturally safer for all animal and plant
life.
* Biodiesel is nontoxic.
* Biodiesel can be safer in
accidents because it has a much higher flash point (300° Fahrenheit) than
regular diesel or gasoline, and is considered a non-hazardous material.
*
Biodiesel is a better solvent, so it cleans engines that have been dirtied and
stained by long-term use of regular petroleum diesel.
* Biodiesel can be
used right now, in any concentration with current petroleum diesel engines,
making the transfer from one to the other very easy. However, older petroleum
diesel engines may experience a higher degradation of seals and gaskets which
can easily be changes for modern plastic alternatives used today.
*
Biodiesel usage dramatically reduces carbon monoxide emissions and carbon
dioxide emissions.
* Biodiesel reduces sulphur emissions by 100% (because
it does not contain sulphur), which will help contribute to the Kyoto protocol
mandate of reducing sulphur emissions.
Proponents say it may replace the
fossil fuels used today to power vehicles. But it still has a ways to
go:
* Biodiesel just like regular diesel tends to gel at temperatures
that are very low, but this can also be rectified with additives.
*
Biodiesel is more expensive to produce by the Gas Companies right now than other
fuels currently in use (although rising costs in fossil fuel production could
outstrip this problem shortly).
* Biodiesel will require a lot of
vegetable oil and animal fat to meet the demand, and critics suggest that land
use dedicated to filling the need will be astronomical, and largely an
inefficient use of land in supporting the demand.
* The EPA reports that
American restaurants produce 300,000,000 gallons of waste cooking oil every
year, and although biodiesel can be produced from it, in the past it went to
producing soaps, etc, but the cost of collecting it has caused Biodieselers to
celebrate because a lot of them are happy to collect it for free.
There
is a lot of support in the potential of biodiesel eventually helping to replace
fossil fuels. In order to generate an accurate calculation on whether it's a
viable alternative or not, there are a lot of things that need to be taken into
consideration. Check out my new book 'The Secrets of Biodiesel' and really get a
handle on this.
Biodiesel commercially, is not cost effective today
because it is not produced in such a large-scale. If it were manufactured on a
larger scale, it may have a greater effect on price. To use a different example,
it costs more-per-car to produce only one or two cars than it costs to produce
10 cars, or a hundred cars, or thousand cars. (This is why Henry Ford is hailed
as a genius of the production industry, because he reduced car prices by
creating an assembly line). So once the scale of biodiesel is ramped up, the
cost will be more effective.
The cost of biodiesel has become very
affordable as a way to fuel cars and heat homes of our individual Biodieselers,
however, replacing the current processing plants that take oil and turn it into
fuel may be so high that it is prohibitive, and asking drivers to switch
vehicles or swap engines may not be an alternative for everyone. So clearly,
there will need to be a "phasing in" effect in order to increase biodiesel or
other bio-fuels, thereby greatly reducing the stranglehold of petroleum-based
fuels.
Another thing to consider is the social cost. While many people do
have the best intentions in mind to reduce emissions and waste and improve on
their use of fossil fuels, people still make decisions based on their own
personal impact; how much money and time will they save? There may be lots of
people that are concerned about ecology, but there are so many more people
concerned about whether they can afford to make the transition. Until biodiesel
becomes the cheaper choice, the general public will not make the
transition.
