The next step is to work on cleaner electricity. While most EU got the message long time ago, eastern bloc countries are much behind. Currently in Poland it is better for the environment to drive a diesel VW Golf than Tesla, as the electricity is produced from brown coal.
That's not true. Even with coal, the end-to-end emissions are better with electric cars. Proof: Poland is 800gCO₂/kWh [1]. With an average electric car (i.e. my hyundai ioniq), you average 11kWh/100km, or .11kWh/km. Taking emissions into account, that gives us 88gCO₂/km. A VW golf is 120gCO₂/km [2] [1]: https://www.electricitymap.org/map [2]: https://www.fleetnews.co.uk/cars/Car-CO2-and-fuel-economy-mp...
From a regular EV I would expect around 16.5kWh.
