The Bottom Line On Electric Cars: They're Cheaper To Own

The price of electric vehicles is coming down, but they still look expensive
compared with many gasoline-powered cars. That comparison, though, is
misleading. Once you figure in the cost of ownership, especially maintenance
and fuel, electric vehicles are a bargain despite the up-front price tag.

This year, the average electric car transaction price decreased by 11
percent from 2016. Some affordable models are the 220-mile range Tesla Model
3 for $35,000 and the Chevrolet Bolt with a 238-mile range for $37,495. The
Nissan Leaf with a 107-mile range starts at $30,000 and the Hyundai Ioniq
with a 124-mile range begins at $22,000, after federal tax credits.

Gas-powered automobiles require replacing parts that go bad over time.
Electric vehicles are different because they do not need as many components
to operate. For instance, electric motors only have one moving part while
engines in traditional automobiles contain dozens.

Items that do not need to be replaced in electric vehicles include oil, fan
belts, air filters, timing belts, head gaskets, cylinder heads and spark
plugs. Thus, keeping an electric car running costs less when compared to
conventional automobiles.

In addition, regenerative braking could extend the life of brakes on
electric cars. Since an electric motor is able to slow itself down, the use
of brake pedals is reduced and brake pads and rotors last longer. Electric
motors are also more efficient because they do not generate and waste as
much heat as combustion engines that need tiny controlled explosions to

However, not all car maintenance is eliminated with electric vehicles. Some
required upkeep includes replacing windshield wipers, suspension and tire
rotation. But routine maintenance will occur less frequently, meaning not as
much time and money would be spent on sustainment.

Another cost associated with electric vehicles is a home charging unit. A
charger that can provide 30 miles of range an hour costs about $600.
Electric vehicle chargers can be purchased from common retailers such as
Home Depot or Amazon.

To make installing chargers more affordable for drivers, some electric
utilities provide discounts. For example, Alliant Energy offers customers in
Wisconsin and Iowa up to a $500 rebate for purchasing and installing a Level
2 home charger.

Level 2 chargers supply 240 volts which is what an electric dryer or oven
needs to operate. This type of charger provides up to 70 miles of range per
hour and could be purchase for about $450.

One of the pricier components of owning an electric vehicle is replacing the
battery, which costs thousands of dollars. Some factors that may shorten the
life of the battery include high temperatures or overcharging. Hence, it is
important to be aware of the battery warranty before purchase.

One benefit of driving a car that operates on electricity instead of
gasoline is that it is not subject to cost spikes due to political
instability. This is because electricity is domestically produced.

The true cost of electricity is dependent on where one lives. Last year,
electricity ranged from about 24 cents per kilowatt hour in Hawaii to about
seven cents per kilowatt hour in Louisiana. The average cost of electricity
in the U.S. is about 12 cents per kilowatt hour.

According to the Department of Energy, charging an electric car costs about
half as much as fueling a gasoline-powered car. The U.S. average per gallon
of gasoline is $2.50 while it would cost $1.10 per eGallon to charge an
electric car, according to a tool developed by the Department of Energy
which compares the cost of driving with electricity by state.

An average person would spend about $540 driving an electric vehicle for the
typical 15,000 miles per year. In some states, electric vehicle owners can
fuel their vehicles to capacity for less than dollar. Oregon is an example
of a state where most drivers spend about $30 per month to charge their
electric cars.

To further decrease transportation costs, utilities could allow parked
electric vehicles to deliver power to the grid and provide owners with a
monetary return. Not only would this allow drivers to make money off their
vehicles, but it would also boost the grid's reliability and resilience.

Power delivered by electric vehicles onto the grid would allow for more
flexibility during peak demand times for less cost. Electric cars could
charge their batteries when prices are low and sell electricity onto the
grid when rates are high. Balancing the supply and demand of electricity
with electric cars could result in avoiding costly upgrades, such as
investing in new power plants.

A year-long study in Denmark conducted by Nissan and Italy's largest utility
Enel SpA demonstrated that electric vehicles could be utilized to benefit
the grid. Nissan and Ovo, one of the United Kingdom's largest energy
suppliers, will offer the vehicle-to-grid service to buyers of the Leaf next
year. Savings from vehicle-to-grid services would cover some costs involved
with charging an electric car.

The bottom line, though, it quite clear. If you buy an electric vehicle
rather than a gasoline-powered one, you are probably going to save a lot of
money during the time you own it. You don't need to be a member of the
Sierra Club to see the appeal of going electric.
