I remember also several important things now. To produce electric cars we as EU member states and also including Germany needs Lithium for the batteries and other rare microelemnts, which is found only in China and China already do a prohibition of export of that rare microelements. So the EU is bumping the heads again into the wall. Lithium is limited into the nature and have to be mined. Only a few countries have Lithium for the batteries for the electric cars. Lithium and Silver will skyrocketing because they are needed also for Solar panels and Batteries for the energy indipendent Solar power plant homes. China is building mixed batteries based on Lithium and Graphene, but still that dirty bastard called Lithium is needed to produce good batteries.
