The Cost of Driving an EV Versus a Petrol Car
Share
“It’s tears at the pump and smiles at the charging station.” — Olof van der Gaag, chairman of NVDE. 😄 And the numbers prove him right.
Let’s compare the cost of driving an EV versus a petrol car over 100 kilometres. For the electric-car calculation, we use a BlueSky charger with a dynamic energy contract.
Cost of driving an EV versus a petrol car
100 km in a petrol car
- Assumed average consumption: 1 litre per 16 km, or approximately 6.25 litres per 100 km
- Assumed petrol price: €2.23 per litre
- Energy cost per 100 km: €13.94
The petrol price used in this example was taken from the ANWB overview of the cheapest filling stations in North Holland on 8 April 2026.
100 km in an EV with a BlueSky charger and dynamic energy contract
- Average consumption: 16 kWh per 100 km
- Average electricity price paid by our users in April: €0.17 per kWh
- Energy cost per 100 km: €2.72
That is a difference of more than a factor of five.
These calculations compare only the petrol or electricity needed to drive 100 kilometres. They do not include other vehicle expenses such as purchase price, depreciation, insurance, maintenance or road tax. Actual costs will also vary depending on the vehicle, driving style and current energy prices.
Solar charging can reduce costs further
The comparison does not yet account for the fact that more than 90% of our users have solar panels and can charge their cars partly using their own solar energy.
Electricity generated by your solar panels does not have to be purchased from an energy supplier at the normal retail rate. This means the effective cost of charging can be even lower, depending on your solar installation, household consumption and the amount of surplus solar energy available.
A BlueSky home charger can automatically adjust charging to make better use of your own solar production. Through the BlueBird Power app, you can monitor charging sessions, energy consumption and available solar energy.
More than a financial difference
But it is not just about money.
Petrol is expensive and polluting, and its price is affected by international markets, regions and political decisions. Every litre you do not need to purchase represents another step towards energy that is cleaner, more local and more resilient.
With a BlueSky charger from BlueBird Power, you can automatically charge during the cheapest periods of the day when you have a dynamic energy contract. You can also make better use of electricity generated by your own solar panels.
Cheaper. Cleaner. Less vulnerable.
