PGE released information documenting the fuel cost savings to owners of electric vehilces at the recent 2017 Portland International Auto Show.
According to PGE, a gas-powered vehicle averaging 30 miles per gallon and driven 12,000 miles per year will use 400 gallons of gasoline. At a recently low $2.50 per gallon, the annual fuel cost is $1,200, or 12 cents per mile.
In comparion, an EV will use approximately 3,000 kilowatt hours of electricity to travel the same 12,000 miles. At an average price of 10 cents per kWh, the owner would spend about $300 to charge the vehicle, or 2.5 cents per mile.
PGE also stressed that because electric vehicles do not use a conventional transmission or combustion engine, additional maintenance costs including oil changes, tune-ups, and other expenses can be eliminated.
