Is Electric Energy Cheaper Than Fossil Fuels for Cars? A Complete Guide
As electric vehicles (EVs) become more popular in Spain, many drivers are asking: “Is electric energy cheaper than fossil fuels for cars?” Understanding the costs of electricity versus petrol or diesel can help you make smarter, greener decisions for your wallet and the environment. In this guide, we’ll explore the true cost of running an EV, compare it to traditional cars, and provide tips to maximize savings.
How Much Does Electric Energy Cost for Cars?
The cost of driving an electric car depends on:
- Electricity rates – Prices vary across regions and providers in Spain.
- Vehicle efficiency – Measured in kWh per 100 km.
- Driving habits – Speed, terrain, and climate affect energy consumption.
Example:
A small EV consumes about 15 kWh per 100 km. At an average electricity price of €0.25/kWh, driving 100 km costs: 15 kWh×€0.25=€3.7515 \, \text{kWh} \times €0.25 = €3.7515kWh×€0.25=€3.75
Compare this to a petrol car averaging 6 L/100 km, with petrol at €1.70/L: 6 L×€1.70=€10.206 \, \text{L} \times €1.70 = €10.206L×€1.70=€10.20
That’s nearly 3 times cheaper to drive on electricity!
Why Electric Energy Can Be Cheaper Than Fossil Fuels
- Higher efficiency – Electric motors convert more energy into motion than combustion engines.
- Stable electricity prices – Less volatile than petrol or diesel.
- Government incentives – Tax reductions and subsidies for EV owners in Spain.
- Lower maintenance costs – Fewer moving parts mean fewer repairs and lower long-term costs.
Factors That Affect EV Costs
While electricity is often cheaper, costs vary depending on:
- Home charging vs. public charging – Public fast chargers can be more expensive.
- Time-of-use tariffs – Charging at off-peak hours can reduce costs.
- Battery efficiency and degradation – Older batteries may use slightly more energy.
- Driving style – Aggressive acceleration increases energy consumption.
Tips to Save on Electric Energy for Cars
✅ Charge at home during off-peak hours – Take advantage of lower tariffs.
✅ Use a smart EV charger – Schedule charging and monitor usage.
✅ Optimize driving habits – Smooth acceleration and regenerative braking help save energy.
✅ Regular maintenance – Keep tires inflated and brakes maintained for better efficiency.
✅ Consider renewable energy – Pairing your EV with a green electricity plan reduces your carbon footprint.
