I was under the impression that EV's are more efficient than petrol. A quick google got me to the article linked below. which says...
"Energy efficient. EVs convert over 77% of the electrical energy from the grid to power at the wheels. Conventional gasoline vehicles only convert about 12%–30% of the energy stored in gasoline to power at the wheels."
