Are you tired of spending significant dollars at the fuel pump and interested in ways to save on your next car?

According to the U.S. Environmental Protection Agency – which actually suggested this topic to us – the cheapest cars to “fuel” don’t take liquid fuel at all, but rather, are all-electric.

How cheap is cheap? A 23-mpg combined 2014 Chrysler 300 with 3.6-liter V6 is one car representing an average efficiency rating and costs $2,400 per year to fill up – or, $1,900 more than one of a few $500-per-year electric cars on our list.

The EPA’s annual fuel cost estimates assume: average fuel/electricity prices and 15,000 miles driven comprised of 55 percent city and 45 percent highway driving. Under each car’s rating, the EPA has a “personalize” link to estimate your actual costs.

EVs are rated by miles per gallon equivalent (MPGe) and most get over 100 MPGe.

But can’t you do just as well with a high-mpg car or hybrid? Not necessarily. The Toyota Prius gets 50 mpg but its gasoline still costs $1,100 per year, more than double the best EVs’ annual energy costs.

Even at double the 12-cents per kilowatt-hour the EPA figures, a Nissan Leaf’s annual electricity bill on 24 cents per kwh juice would just equal the Prius at $1,100 annually.

Of course an EV involves acquiring a home charger, and accepting range limitations, but there’s a growing contingent of people who’ve jumped in and say the EV waters are fine – some having purchased, and others leasing to avoid long-term commitment.

Unfortunately however, some of the cars on our list are what are called “compliance cars” to meet California mandates. Only four cars are sold in all 50 states, some are sold in several states from east-to-west, and others are quite limited indeed.

For those who “get it” now, EVs are also gratifyingly zero emissions vehicles, and even factoring in “dirty coal” as the energy source, they wind up being cleaner in most cases. And, no soldier or civilian has ever been killed over the right to electricity extraction from the Middle East, nor do we need to transport electricity by tanker across the sea. Nope, we make it here, in the U.S., and the grid is getting cleaner year by year.

EVs also qualify for up to a $7,500 federal tax credit and state credits where applicable.

So, without further ado, here’s the list ranked by annual energy cost or MPGe:
