Electric Cars for 2010: Shift from Foreign Oil to Riding on Local Renewable Energy

Plug-in electric cars will reduce but not eliminate CO2 emisions. 50% of our electric power is generated by coal fire power plants, 10% by nuclear and the rest mainly by natural gas along with some hydro, solar, wind etc. Power plants, especially combined cycle, are generally more efficient than internal combustion engines by about a factor of 2. So, there would be a reduction in CO2 even if all the power came from coal fired power plants.
