On the face of it Bio-fuels seemed a good idea. Instead of using fossil fuels, which will eventually run out anyway, here was a fuel solution made from renewable sources. Already used in commercial trucks, soy bio-diesel is considered by many as environmentally friendly. Another bio-fuel, corn ethanol is also being added to gasoline, to give it some “Green” credentials.
The trouble is, to grow enough crops for both fuel and food, more arable land is needed. Already large areas or previously “natural” habitats, are going under the plough. Literally, extra thousands of acres of rain forest around the world are now been cleared and planted up with soy and corn crops, all in anticipation of the demand for their new uses.
This in turn means that the net carbon footprint of producing these fuels from renewable sources is actually far higher than that caused by using conventional fossil fuel. Instead of reducing the carbon footprint as everyone hoped, bio-fuels production is causing nearly four times as much carbon di-oxide pollution than the fossil fuels they hoped to replace.
A recent European report makes for some scary reading. While conventional diesel and gasoline have an indirect carbon footprint of 85kg of CO2 per Gigajoule, Soya-beans have a staggering Carbon Footprint of 340kg of CO2 per Gigajoule. European Rapeseed is slightly better, but still nearly double conventional fuels with a Carbon Footprint of 150kg of CO2 per Gigajoule.
Added to this, the amount of indirect resources used to grow these bio-diesel crops is high as well, when compared to the production of conventional fossil fuels. Especially, when land clearance and water use is taken into consideration. Then there is the hidden cost of vehicle maintenance. Not many people realise that when ethanol is added to gasoline, it can have a long term deteriorating effect on the engines they fuel. There is also an unwanted reduction of overall mileage efficiency. This can be nearly a 25% reduction with some vehicles.
As for the environment, as previously stated, we are loosing even more rain forest ,which cannot be a good thing. Around the world, especially in poorer nations, where land and labour is cheaper, native crops are being replaced by others, like rapeseed, that are being grown solely for fuel. This in a time of growing food and water shortages. In the long term, this will affect consumers in the West as well, in the form of ever increasing food prices. Again, this is at a time when many people are already feeling the financial pressures and strain of a collapsing economy.
So at the end of the day, sadly, the present range of Bio-fuels are not really going to prove to be of much benefit. Even fossil fuels at this stage seem to preferable but this really is the lesser of two environmentally damaging evils. Still, there is hope, as many emergent new fuel technologies are been developed.
The only danger is that financial institutions, that have tightened their belts when it comes to lending money for research, will settle for what they know and continue to support the now impaired “bio-fuel Venture” that now seems doomed to failure.
Then again we always use to have an efficent bio-fuel in straw and hay and the “engine” we all used had a low carbon footprint, low production costs, and produced a useful byproduct, instead of enviromentally damaging waste. Considering the short time that the combustion engine has been in use, compared to the thousands of years that came before it, perhaps we should consider going back to the horse and cart for transport.


I am continually referring to the natural world around me for the starting point for my artwork. In my Garden I can watch the light as it plays across the leaves, caused by the sun's reflections in the pond or the swaying patterns of shadows they create on the path. Above my head are amazing intricate laceworks, caused by the interlaced crossing of slender branches with their delicate leaves. The tactile surface of the bark on the trees. The solitary fallen leaf. Any of it might form the basis for a composition.
