Purchasing a new car presents itself with a lot of possibilities to be green, save some green, and get going in style. Rising gas prices create consumer demand in alternative sources of transportation which resulted in automobile manufacturers providing a large range of electric options. We will post information on hybrid technology soon, but for now lets stick with traditional vehicles (gasoline powered) and electric as two distinct categories to compare.

Vehicle kWh per mile Avg. use kWh per 100 miles Avg. MPG Gallons per 100 miles Cost
Nissan Leaf .24 24 0 0 $2.40
Nissan Versa Hatchback 1.8S 0 0 28 3.57 $14.28
Ford Focus Electric .303 30.3 0 0 $3.03
Ford Focus SE5 Doors 0 0 28 3.57 $14.28
Mitsubishi i-MiEV .258 25.8 0 0 $2.58
Mitsubishi Lancer ES 0 0 26 3.85 $15.40

$/kWh = $0.10 , $/gallon = $4.00

Unfortunately gas prices change every day and electricity has different costs based on local utility companies. A great way to keep your costs constant is independently producing your energy with renewable energy sources like solar panels. We used the values of $.10/kWh and $4.00/gallon…

There are many factors which affect the actual mileage and cost per mile accordingly. For example, any car whether electric or conventional may perform not at their best under the following conditions:

Driving conditions – you might drive less miles per one charge of the battery or per gallon of gasoline in summer and winter months compare to fall and spring months. It generally depends on extreme temperatures that are outside and weather conditions. Therefore, the more energy your car uses to heat or cool the cabin the faster your battery will exhaust or more fuel will be taken. Too strong winds might affect your energy surplus because then it may require using much more electricity and gasoline to overcome air resistance.

Cargo and topography come also into play because your heavy loads and driving up steep long inclines will reduce range also. The range can be decreased by your driving style. If you are a careful driver and use smooth acceleration and deceleration then it will extend range. On the other hand, your excessive acceleration and deceleration might reduce it significantly.

Note: all numbers are a simple prices comparison which might vary or change by car manufacturers at any time as well fuel prices are constantly changing. The data is a general idea what are the main expenses for conventional and electric vehicles and it is only a driver’s decision which car to buy after analyzing budget, practical needs and preferences.

How Green Are Electric Cars? Depends on Where You Plug In
An electric vehicle is only as green as the options around it. Depending on the fuel mix in a particular area the environmental impacts from plugging in an electric vehicle can be quiet different. In the end the difference isn’t just gas vs. electric. Its just gas vs. every option and technology available for producing electricity. Have some freedom and enjoy the choices of coal, natural gas, and oil if you want but also open yourself up to solar, geothermal, wind, hydro, and so much more. With electric you have consumer demand, independence, and a voice in what moves you.

If you live anywhere in the United States you can find out your energy portfolio using the EPA Power Profiler
