Charging at night time uses base load, so greater proportion of nuclear power.
Maximum efficieny of a gasoline engine is about 30%, versus 96% for an electric motor, though the battery does have less efficiency.
Electricity generated at a power plant using fossil fuels and steam turbines is more efficient than locally in an engine.
It's cheap to transport electricity over wires. Fuel still needs to be piped and trucked.
So even if your electric car was powered by fossil fuels at the power plant, it's still more efficient.
