content: You have no idea how cheap charging an electric car is versus running on petrol. Heck, if you're like me and have solar you can charge your EV from that rather than worrying about paying for the electricity. Our car costs $1 for 100km (60 miles.) How much is a gallon of petrol these days? $3? More? Here it costs $2 a litre which is about $8 a US gallon and a typical car will need 10 litres to cover 100km so that's $20 to cover the same distance my EV will do on $1.
