Yes they are/will be a viable alternative, but not for every application.

The pollution equation is indeed complex and varies hugely from country to country and region to country. Take a country like Norway, which to my knowledge has a very high percentage of renewable energy in its mix - here e-cars really make a significant net pollution reduction contribution. For other countries it is questionable whether burning gasoline in an ICE engine produces more pollution than producing electricity for e-cars from dirty old fossil fuel power station. Personally I think not, but clearly it varies a lot from region to region.

My guess would be that the efficiency of a modern petrol ICE >30%, whereas an old power station <20%. Efficiency of an e-car can easily be 80-90% or more. Maybe someone has better figures? Varys country to country, you say ;)
