1. What is the Energy Cost Comparison?

This calculator compares the energy costs between gas-powered and electric vehicles based on your driving distance, vehicle efficiency, and local energy prices. It helps you understand the potential savings of each vehicle type.

2. How Does the Calculator Work?

The calculator uses these equations:

Where:

• \( Miles \) — Distance traveled
• \( MPG \) — Miles per gallon (gas vehicle efficiency)
• \( Gas\ Price \) — Cost per gallon of gasoline
• \( MPGe \) — Miles per kWh (electric vehicle efficiency)
• \( Electric\ Rate \) — Cost per kWh of electricity

Explanation: The equations calculate energy consumption based on vehicle efficiency and then multiply by energy costs to get total expense.

3. Importance of Energy Cost Calculation

Details: Understanding these costs helps in making informed decisions about vehicle purchases and estimating long-term operating expenses.

4. Using the Calculator

Tips: Enter your expected annual mileage, your vehicle's efficiency ratings (MPG for gas, MPGe for electric), and your local energy prices for accurate comparisons.

5. Frequently Asked Questions (FAQ)

Q1: What is MPGe?
A: Miles Per Gallon equivalent (MPGe) represents how many miles an electric vehicle can travel using the same energy content as one gallon of gasoline (33.7 kWh).

Q2: Should I include maintenance costs?
A: This calculator only compares energy costs. Electric vehicles typically have lower maintenance costs which could further increase savings.

Q3: How accurate are these estimates?
A: They provide a good baseline comparison, but actual costs may vary based on driving conditions, temperature, and other factors.

Q4: Should I use local electricity rates?
A: Yes, electricity costs vary significantly by region. For most accurate results, use your actual utility rate.

Q5: What about charging losses?
A: The calculator assumes 100% charging efficiency. In reality, about 10-15% of energy may be lost during charging.
