Editor’s note: In the article below, the writer uses the term “up to” several times in discussing potential yearly savings from driving an electric car. I understand the temptation to use such phrasing, and it’s quite common to do so, but it’s a highly inaccurate way of phrasing it for this topic. Annual savings depend on a lot of factors, and in doing an analysis like this, you have to make a lot of assumptions. I assume the analysis uses averages in every opportunity possible .
The largest savings were found in areas with high gasoline prices, low electricity prices, and where drivers drove longer distances, and used older, less fuel-efficient vehicles.Adoption of Plug-In Electric Vehicles: Local Fuel Use and Greenhouse Gas Emissions Reductions Across the U.S. Researchers found that states with older vehicles have highest potential to save with an EV. Idaho has the highest savings — up to $2200 per year — where less fuel-efficient vehicles are common along with high gas prices and cheap electricity. Washington and Oregon are also high on the savings list.
