> Unless some fantastic new battery is invented very soon, there literally isn't enough lithium on earth to support the electric car market and lithium ion batteries are soon going to become prohibitively expensive.

And unless the power networks from a lot of countries are not modernized. Not sure about the States, but over-here in Eastern Europe we get power-cuts from time to time during summer months because everybody has their AC turned on (they usually don't last long, but it happens). If half of the 1 million cars that are now driving on the streets in my city were to be electric then I'm pretty sure that the local power network will just give up spectacularly.
