Wells to Wheels
What Does it Mean?
What does "Wells-to-wheels" mean?
Wells-to-wheels emissions take into account the production and distribution of the fuel. It is a type of analysis that allows individuals to compare emissions over the entire life cycle of a vehicle —from the energy and materials used to power a vehicle, to the direct tailpipe emissions. This makes it more “apples-to-apples” when comparing to gas-powered rides. For example, although EVs produce no tailpipe emissions, the electricity used to power them does produce a certain amount of emissions, albeit notably less than a conventional car.
A wells-to-wheels analysis tracks emissions across two stages: well-to-pump and pump-to-wheels. The well-to-pump stage begins with the fuel feedstock recovery, followed by fuel production, and ends with the fuel available at the pump. The pump-to-wheels stage simply represents the vehicle’s operation.

EVs cost about 75 cents per gasoline gallon equivalent when driving on electric power. The price of gasoline is expected to rise by about 65 percent between 2009 and 2015, while the price of electricity is more likely to remain stable. Source
