Charging an electric car is generally cheaper than fueling a gasoline-powered car. However, the exact savings depend on several factors, including local electricity and gasoline prices, the efficiency of both the electric vehicle (EV) and the gasoline vehicle, and your driving habits. Here's a comparison to illustrate the cost differences:
1. Electricity vs. Gasoline Costs:
Electricity Cost:
- The average cost of electricity in the U.S. is about $0.13 per kilowatt-hour (kWh), though it varies by location.
- The average electric vehicle consumes around 25-30 kWh to travel 100 miles.
- At $0.13/kWh, it costs approximately $3.25 to $3.90 to drive 100 miles in an EV.
Gasoline Cost:
- The average cost of gasoline in the U.S. is around $3.50 per gallon, though this can fluctuate significantly.
- A gasoline car with an average fuel efficiency of 25 miles per gallon (mpg) requires 4 gallons to travel 100 miles.
- At $3.50 per gallon, it costs $14 to drive 100 miles in a gasoline car.
2. Comparison Example:
- EV Example: If you drive an EV that uses 30 kWh per 100 miles and your electricity rate is $0.13/kWh, your cost per 100 miles is $3.90.
- Gasoline Car Example: If your gasoline car gets 25 mpg and gasoline costs $3.50 per gallon, your cost per 100 miles is $14.
Savings: In this example, driving an EV costs about 70% less than driving a gasoline car for the same distance.
3. Additional Considerations:
- Maintenance Costs: EVs generally have lower maintenance costs because they have fewer moving parts and don’t require oil changes, which adds to the overall savings.
- Public Charging: If you rely on public charging stations, especially fast chargers, the cost can be higher than home charging but still often cheaper than gasoline.
- Time of Use Rates: Charging at home during off-peak hours can further reduce costs if your utility offers Time of Use (TOU) rates, making EVs even more cost-effective.
4. Regional Variations:
- Electricity Prices: In areas with high electricity rates, the savings might be less pronounced, but EVs are usually still cheaper to operate than gasoline cars.
- Gasoline Prices: In regions where gasoline is particularly expensive, the savings from driving an EV are even greater.
5. Long-Term Savings:
- Over the long term, the cost savings from driving an EV can add up significantly, making the total cost of ownership lower compared to a gasoline car, despite the typically higher upfront cost of an EV.
Conclusion:
Charging an electric car is typically much cheaper than fueling a gasoline car, resulting in substantial cost savings over time, particularly when charging at home. The exact savings will depend on local energy prices and the specific vehicles being compared.
