EV's

As the United States and the world runs headlong into electric cars many potential problems go by the wayside. The number of charging stations needed is often discussed but where the station gets its power is not mentioned. It so happens that most people will charge their cars at home at night but this puts an extra load on transformers that are designed to cool at night. Add to that summer temperature where the air conditioners run at night and many transformers are not able to carry the load. As the demand for charging increases the stress on the already over loaded grid reaches a brake point and new transmission lines must be installed. This is followed quickly by the building of new power sources which means windmills and solar panels and all of this including the batteries for cars means more mining and refining. Then what is done with all the materials when they wear out. On top of all this people like electric cars until they have one and then are not that excited about buying another one sort of like convertibles in times past. Every body wanted one but one was enough.
