Hello everyone, I learned last week that oil refineries use electricity that is not taken into account in the CO2 calculation. That is, they consume a huge amount of electricity! So much that the refineries have refused to publish these values since 2006. Maybe one or the other should think again before starting an “efficiency discussion” of electric cars and power plants to consider these values. It was once said that with Here is a page with the latest data from 2005:http://www.nationmaster.com/…/Consumption-by-petroleum-refineries This would mean that the combustion engine not only burns fuel, but also electricity that had never been included in the balance sheet before. I believe that if you know that, then any discussion about the efficiency of electric cars will be unnecessary. No matter how economical a verbren This is also a nice video about the topic, unfortunately only in English:http://youtu.be/BQpX-9OyEr4 saludos joered
