A Tesla S running on coal generated electricity is still going to produce less emissions than most cars, the big turbines at power plants are more efficient than the light weight engines in cars.
Don't forget the inefficiencies of transmitting power over power lines for ... there is plenty lost there too. If it wasn't for this problem, there wouldn't be AC power, it would all be DC. But even AC will see losses from transmission.
There are losses in transmission, but there is also some inefficiency in transporting and storing petrol.
Think about the Bloom box [1] -- if the cost ever gets down as low as expected, then solar will be a very expensive alternative or a similar example [2] that was /invented/ in Victoria, but was exported overseas because of lack of government support (unless I am mistaken).
But that needs gas and gas prices are going to rise steadily. If we get the fracking that the government wants then gas prices will rise dramatically. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
