Annual Fuel Savings (EV) vs Electricity Rate
公式
## 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.
