Over in Sweden it would be hard to replicate these results. Gasoline is ~18SEK/l ($7.5 per gallon).
My electricity production cost changes by the hour, so I can steer my cost by charging when it’s costs are low. Taxes and transfer costs give me a minimum of about $0.07/kWh. A smart charger that picks when to charge based on price can probably average you a cost of $0.10/kWh over the year.
The EU has strict climate goals to push away from fossil fuels. The current goal is to ban the sale of new combustion engine cars by 2035.
The fuel here contains a bit more renewables, which also costs more o produce. Still, more than half of the cost of fuel is tax. They had a nice tax break for buying a new electric car for a while, but that window has passed.
