   Those mistakes were done in the past but now you find more wind mills   
   out on the sea plus attempts are being made to distract the birds before   
   they are flying in to a wind mill.   
   What about airplanes?   
   Birds fly in to airplane turbines once in a while.   
   We will use dirty energy first to create machines that produce clean energy.   
   Then we will use clean energy for the first step of production too.   
   I am not a fanatic.   
   If we can reduce CO2 emission by half and reduce our energy consumption   
   by making better use of energy it would be enough.   
   We have reached peek oil anyway and from now on oil can only get more   
   expensive.
