So here we are for my third and last article about the World Forum for responsible economy in Lille 2012.
This time I will report the conference “The third industrial revolution : renewable energies”.
This conference was split in three parts :
– Energetic mix in Roquette (biochemistry, potato starch specialist)
– Negawatt and network optimisation by Mr.Jaquin of Schneider Electrics
– Energetic revolution in Brasilia by Mr.Rielly of Renovaveis
Energetic mix : the future
Roquette is a french company specialised in the treatment of potato starch and its chemistry.
The company started thinking about renewable energies when it came out that the source of all energies in the world is biomass and starch is the most flexible biomass product. It can be used as a way to produce polymers, energy (our body consume starch to live)… So what does Roquette do to include biomass -and other renewable energies- into its consumption?
Mr Roquette takes the example of his factory in Alsace – East of France- that has reduced its consuption of gas of 25% and in fine it gas has to be only 20% of the consumption of this factory. It is not enough. CO2 is released by the very production of starch. The factory found one solution : Almost 50% of carbon gas is sent to a tomatoe hydroponic cultivation that needs that gas !
About electrical production, it is assured by two sources : a wood unity -which is fed by the underused local forest- and a geothermal plant.
As a conclusion, Mr Roquette underlines a simple figure : From one provider -with nuclear, fuel and gas production (EDF)- Roquette opened to more than 10 (wood , water, farmers…). It has several pros. First of all : it is local, not centralized. Roquette saves so much because there is less inline loss. Moreover, it reduces the risk of a cut.
Mr Roquette concluded his talking with a proposition : what if the European Union took the head of industrial projects that deal with energy sources by applying an old mecanism that consist in deducting when we import (with tax) and giving back when we export (subvention)?
Negawatt in France and expansion in Brasilia?
Mr.Jaquin and Mr Rielli introduced us about two totally different situations :
In France -and more generally in Europe- we’re making huge efforts to reduce our consumption because it becomes very difficult to pay hydrocarbons, and winter peaks are hardly handled by the network.
In Brasilia, everything is growing up, especially middle class. Something that can look weird to us is that the first purchase of a new middle class familly is… a fridge.
That means an exponential consumption and even if Brasil has ressources, this power has to be provided as soon as possible. As a consequence, renewable energy are a choice that they are forced in because they are local whereas nuclear plants are centralised.
This world forum was really focused on the ideas J.Rifkin developps in his book “the third industrial revolution”, the need of energetic driving by information was the main idea. I think the best conclusion I can bring is just “we have to make it plural” : more technologies to produce, to save, to share… Centralism, monopoly and specialisation are not welcome in the 21th century.
