Ernie,

Could you  provide some data source for this claim?  I understand  
that electricity is produced with fossil fuels but I also believe  
that electric cars are so much more efficient  than internal  
combustion heat engines at providing transportation.  So how do the  
efficiencies compare between CO2 emissions at the source (tailpipe vs  
smokestack)?
