A Better Way To Compare Gas & Electric Prices - CleanTechnica

The article from CleanTechnica addresses the challenge of comparing gasoline and electric vehicle (EV) fueling costs, noting that traditional metrics like MPGe (miles per gallon equivalent) are technically accurate but not user-friendly for everyday budgeting. Instead, the author proposes a new metric called the “Fair eGallon,” which translates electricity costs into a gasoline-equivalent price based on the actual work done to move a vehicle the same distance. This approach accounts for the real-world efficiencies of internal combustion engines (about 20%) and electric motors (about 80%), including factors like regenerative braking limitations at highway speeds. By dividing the energy content of a gallon of gasoline (33.7 kWh) by four, the Fair eGallon is defined as 8.4 kWh of electricity, allowing consumers to multiply their electricity rate by 8.4 to get a comparable gas price. Using this method with 2026 U.S. averages, the article finds that home charging at $0.18
