   Thank you, Your Honor!   
      
   Energy must also be reserved to repair and build the power-generation   
   facilities, be it solar panels or wind farms. All these facilities need   
   factories to produce, and factories themselves need energy.   
      
   I am wondering how all those big solar-panel farms process dead panels   
   without polluting their underground water ... :)
