Annual Fuel Savings (EV) vs Electricity Rate

How to Compare EV vs Gas Costs
EVs are typically cheaper to fuel and produce less CO2 even accounting for electricity generation.
Formulas
EV Fuel Cost = Miles * (kWh/100mi) / 100 * Electricity Rate
Gas Fuel Cost = Miles / MPG * Gas Price
EV CO2 = Miles * kWh/100mi / 100 * Grid Factor / 2,204.6
Gas CO2 = Miles / MPG * 19.6 / 2,204.6
计算示例
Driving 12,000 miles/year comparing an EV (30 kWh/100mi) at $0.15/kWh to a gas car (28 mpg) at $3.50/gal.
- 01EV fuel cost: 12,000 * 30/100 * $0.15 = $540
- 02Gas fuel cost: 12,000 / 28 * $3.50 = $1,500
- 03Annual savings: $1,500 - $540 = $960
- 04EV CO2: 12,000 * 0.30 * 0.92 / 2,204.6 = 1.50 metric tons
- 05Gas CO2: 12,000 / 28 * 19.6 / 2,204.6 = 3.81 metric tons
常见问题
How much cheaper is an EV to fuel?
EVs cost about 60-70% less to fuel than gas cars. At average US rates, an EV costs about $0.04/mile versus $0.12/mile for a 28 mpg gas car.
Are EVs really better for the environment?
Yes. Even on the average US grid, EVs produce 50-70% less CO2 than gas cars over their lifetime, including manufacturing and battery production.
What about home charging costs?
Most EV owners charge at home overnight. At $0.15/kWh, a full charge for 300 miles costs about $13.50 compared to $37.50 in gas for the same distance at 28 mpg.
