There are around 270 million passenger cars in the EU+UK.
Assuming they drive around 12,000 km/year and use around 800 liters of gasoline/diesel for that, their final energy demand is around 8 MWh/year each, and 2,000 TWh in total. That’s around 1/6 of total final energy demand.

If you’d replace all of them by electric cars, those would use 2-2.4 MWh/year each, so around 600 TWh in total.
This would reduce EU+UK final energy demand by over 10% (from 12,000 to 10,600 TWh), and increase electricity demand by 20% (from 3,000 to 3,600 TWh).

So just this passenger car replacement would drive up the share of electricity in EU+UK final energy demand from 25% (3000/12000) to 34% (3600/10600).
OK, that was back of the envelope. Would be nice to redo with more precise numbers, but should be in the ballpark.

So where you'd think electricity production would have to grow by over 1/3 to bring its share in total (final) energy demand from 25% to 34%, in this example growing it by 1/5 is sufficient.
The much higher efficiency of the electric car does the rest.
