An electric car is a type of car that runs on electricity. Because it runs on electricity it is a zero emission car, a car that doesn't produce pollution at the point of use. It is probable that some type of fossil fuel would have been used to generate the electricity in the first place, in some cases all the electric car really does is move the pollution somewhere else.

Hype vs. Facts

Zero emissions sounds wonderful but it's not entirely true. While electric cars typically emit less CO₂, over its lifetime a Tesla S will emit about 13 tonnes of CO₂. The production of its batteries alone will emit 14 tonnes. [1]

Coal power still accounts for 39% of America's electricity power. This means that electric vehicles will still be responsible for producing CO₂. In these states, a traditional car has less of an impact to the environment. [2]

In coal-fired Colorado, a gasoline car with fuel economy better than 35 miles per gallon will be better for emissions than the average electric car

A North Carolina State University study showed that a nation full of electric cars powered will make no ecological difference. [3] This is due in part to its production costs, rare metal mining, energy consumed over its lifetime.

The battery is the heart of electric cars. Disposal of batteries is an environmental concern. Dead ones can't be tossed in a landfill and few companies will recycle lithium batteries and electric cars have many large batteries. Seasonal weather changes, such as extreme cold, affect battery performance. In 2014, batteries measured to be half as efficient than in normal operating temperatures. [4]
