I've never really bought the argument that biofuels are causing a food
shortage considering that there is still so much unused farmland in the US
and farming practices here in the EU.  I must admit this out of my field so
I have no real evidence to support my suspicion, but there have been a
trickle of articles from publications like Der Spiegel and the NY Times
which indicate there is some suspicion these shortages have just as much to
do with commodity speculation and manipulation.

Even worse,
Why is there subsidy on bio fuels that get produced out of food eaten  
by poor people?

This causes as we speak people dying as they can no longer for a cent  
or so buy food made out
of it; the prices have doubled if not more for such types of cheap  
food because of subsidy in the
1st world countries for this.

I assume EU will take measures to turn back those subsidies on bio fuels
that get produced out of food that feeds billions, who now hardly can  
afford to buy food anymore as
it gets burned for energy in first world countries, whereas  
commercially spoken it cannot get burned,
it is just because of subsidy it can exist.

Even better i would be in favour of a ban on bio fuels that are  
outright food products in 3d world countries.

When i just walked previous week into a shop and my sister was  
interested in a new washing machine,
i pointed her to the fact that the thing she was interested in, was  
eating 3.8 kW, versus the 100 euro more expensive
thing next to it was eating 1.14 kW. It is something that only very  
few will notice.

It is easy to cheaply produce equipment that eats more power than  
equipment of competitors, that is the fundamental problem.
