Biofuels: false good idea?

crude vegetable oil, diester, bio-ethanol or other biofuels, or fuel of vegetable origin ...

But no, it's very good biofuels, especially diatom oil.
It's just that you will not forget to use them to fix
greenhouse-effect gas.
And yes, we are talking about producing to consume, but we fail to produce to repair!

ps to christophe and to all: site and forum very informative.

As usual, it takes a while to notice the bullshit that has just been done; and yet all this was predictable.

The negotiations on global warming this week in Bangkok come against a backdrop of harsh criticism of agrofuels, improperly called "biofuels", which are no longer considered a miracle solution ...
But experts say the demand for agrofuels is causing unfortunate effects for the global economy and food security, and could ultimately cause more harm than good to the environment ...

The cultivation of some agrofuel source plants also implies major environmental aggressions.
This is the case in Indonesia: this archipelago has become the world's leading producer of palm oil, grazing immense natural forests, especially on peat bogs, a very special ecosystem composed of an accumulation of organic matter.
A peatland forest contains thirty times more carbon than a normal rainforest and turning it into a plantation results in the release of huge amounts of carbon stored in the soil.
A study published in February in Science magazine concluded that it would take 840 years for biofuels from Indonesia's peatland plantations to erase the "carbon debt" generated by the transformation of this natural environment ...

"Each time that in a country a cultivated surface is dedicated to fuel, the price (of the cultivated food) goes up and other farmers produce more, by extending largely on forests and pastures", underlines Timothy Searchinger, an expert from the American Georgetown University.

The Germans lower their arms. Germany renounces forced and forced development of biofuels.
http://www.orange.fr/bin/frame.cgi?u=ht ... -2009.html

Germany had to give up Friday one of the pillars of its environmental policy, the massive development of biofuels, a bitter setback for a country that is pioneering in this area.
"All together, we underestimated the problems", admitted the Minister of the Environment, Sigmar Gabriel. An admission that condemns E10, the new fuel that Berlin wanted to impose from next year and which contained 10% ethanol mixed with conventional gasoline.

Far too many cars in circulation in Germany are unable to support it for technical reasons - more than three million according to the latest published figures, very far from the one million barrier set by the minister.

Motorists who could not have put E10 in their tank should have fallen back on Super-Plus, more expensive.

"Environmental policy does not take responsibility if millions of motorists have to pay more" for their gasolineexplained the Social Democrat.

For several weeks, Sigmar Gabriel had to face growing criticism against his strategy of reducing greenhouse gas emissions.

The ADAC motorists' club refused the additional cost of E10, relayed by politicians of all stripes, and the ecologists themselves denounced the methods of growing rapeseed or soya to make agrofuels, which compete with food plantations.
"Biofuels represent a danger for biodiversity, they impose massive pressure on the tropical forest and destroy the natural sensors of greenhouse gases contained in uncultivated soils," Christian Hey, secretary general, told AFP. of the Federal Office for the Environment (UBA).

Friday, however, the Minister of the Environment has defended his ambitious strategy step by step: Germany wants to go faster and further than the European Union to reduce CO2 emissions, with a decrease of 40% between 1990 and 2020 , against 20% for the EU, and will continue to bet on biofuels ... but second generation.
"Today is a bad day for climate protection", moreover immediately denounced the association Greenpeace, radically opposed to agrofuels.

Waiting for the second generation, which should not happen for several years according to the expertsit is other sectors of the industry that will have to bear the car's mistakes. The goal of 40% emission reduction remains sustainable if the share of renewable energy in power generation increases to 30% by 2020, instead of 27,5%, announced Mr. Gabriel.

A way to pass on the baby that is not to the taste of the energy industry. A renewables share of 30% "is very ambitious, but feasible", however "only under certain conditions", commented a spokesperson for the BDEW federation. Among them, the construction of high voltage lines to transport the electricity produced by wind turbines to the coast.

Another problem was that biofuels were to help the German car industry, which specializes in large fuel-efficient and more polluting sedans than small cars, to meet the European Commission's target of 120 grams of CO2 emitted per kilometer.

Manufacturers will now have to find "other technical measures" to achieve this, according to the minister.

"We know we still have a long way to go with our bigger cars",
Moreover, Matthias Wissmann, president of the German manufacturers' federation, said in a plea for second-generation biofuels.

Will it be better to think of gillier / pantone?
And what's worse, lowering the price of rapeseed oil? :D
And France, will she follow?

bham : I was going to post this info; I came across the key

The lobby of the car has won as the corn lobby will do in France for GMOs.

It would be better to stop meeting in Bagkok, IPCC, Al Gore Grenelle Paris..etc ..; it's all pipo.

Germany is building 20 coal centales (open pit mines).

Manufacturers will now have to find "other technical measures" to achieve this, according to the minister.


But what technical measures to reduce CO2 emissions from these big sedans? Mrs Merkel what do you propose?

Help Remundo, comes to defend the Germans : Lol:

Well, I think it's good news because it's a brave challenge to a pioneering biofuel country. It has already been said on this forumagrofuels are far from being a panacea, especially for environmental reasons.
What does it involve?
-Investments made at national or individual level are reduced to nothing, the economic consequences are probably very important and unfortunate but they have the courage to do so.
-A challenge for the German car manufacturers and for a part of the German industry.
-An acceleration of studies for 2è generation biofuels (from coal?).
-A faster evolution than expected for more fuel-efficient cars, with engines even more optimized (Gillier / Pantone?), Which also leaves the field to electric cars.

In short this temporary difficulty, they will undoubtedly make it a strength by damning the pawn to everyone and by maintaining a pioneering position necessary for the good health of their industry.

By comparison, in France we began to use “agrofuels” later, the investments made being less important. Compared to the new "CO2" deal, we are doing quite well, both for nuclear power and for our cars, mostly diesel-powered and small in size and therefore low in consumption (compared to large German sedans). For the moment, therefore, we have an undeniable advantage, but which can turn into a disadvantage if we stick to what we have learned, which is likely to happen.

Unless they are biofuels produced from the anthrax : Mrgreen:
