Nationally, though, the Democrats are going to have to get over their squeamishness about nuclear power, to make this work. I hope the next batch of Republican presidential candidates make that a priority, using the National Security argument. If we don't need foreign oil to run power plants, that reduces our dependence on regimes that support terrorism, and reduces the dollars going to them.
The current Saturn Vue would make a poor "plug-in" hybrid. The electric motor is only to boost the gas motor so the vehicle really cannot be driven on electric alone.
It makes for a more efficient gasoline motor, but can't be made to go full electric (unless you are happy with 20 mph max speeds or a 10 mile range).
Next year's (2008) model uses a different driveline which will make a Plug-in hybrid possible.
