It takes about 15 to 20 kWh to power an average user scale electric/plugin vehicle for about 100 km. In the US, where the distance travelled for personal transportation is more than 3 billions miles per year, http://www.fhwa.dot.gov/ohim/tvtw/10febtvt/figure1.cfm they will need more than 900 TWh/year of electricity, or the total nuclear electricity US production. Pratically, personal electric vehicles are only *one possible* strategy to electrificate transportation (both of goods and people) and home heating/conditioning with efficient electric pumps

I guess a mix of nuclear (including in the near future thorium reactors, read a post of some days ago), renewables and natural gas plants, in this order (nuclear and reliable renewables like geothermal and biomass for the base load, intermittent renewables when and where available, hydro and eventually gas plants for the peaks, including heat pumps demand) But I think that the question is badly posted, even with no nuclear or renewables, you gain a double efficiency using an electricic vehicle rather that a petrol engine and an efficient heat pums (instead a gas boiler), even if all the kWh came from a quite efficient natural gas CC plant
