How Green Is an Electric Car? Depends on Where You Are

A common criticism of electric cars is that they’ve simply got “long tailpipes”—that is, they still pollute, albeit at the power plant where their power is generated rather than at the auto itself. But this critique ultimately doesn’t hold much air, our sister publication Mother Earth News has found after crunching the numbers on electric car emissions:

In terms of climate change emissions, electric cars are generally much cleaner than conventional gas vehicles. In areas of the country that have the cleanest power generation (more wind, solar and hydropower), electric cars emit far less greenhouse gases, not only compared with conventional vehicles, but also compared with efficient hybrid-electric vehicles. In areas of the country with the dirtiest power generation (coal), an efficient hybrid may be your best environmental bet, though if you’re gentle on the pedal, an electric car may yield comparable results. On a national average basis, an efficient electric car emits about half the amount of carbon dioxide as a conventional car, and roughly the same amount as an efficient hybrid.

Read the full article to learn about all the factors that determine auto efficiency and emissions, and see the accompanying U.S. map of electric car CO2 emissions by region to get a sense of how your area stacks up. 

The next time you hear the long-tailpipe argument, you’ll know enough to challenge this bit of common nonsense.

Electric car is an automobile which is totally pollution free. Electric car has so many benefits over conventional internal combustion engine. Combustion engines are emitted poisonous gases which is very dangerous for the environment. Electric cars are cheap as it totally depend on its battery. If there are so many pros factors then why not to use electric cars . http://shoresautomotive.com/bmw-repair/

Electric cars produce low emission than the other cars so as per the use of the car, performance also far better. As per the use of the electric car, power should be needed for the better use and future so how can we use in a proper way for the low electric consume is important. http://www.monacomotors.com/

Green as in economical and environment friendly. Americans have been reacting to the gas price hike by changing their car buying habits. Small automobiles that sip from the tank in the lightest manner possible have proven to be the best sellers, as buyers have been avoiding less useful and more costly green choices. The proof is here: http://www.cardealexpert.com/news-information/auto-news/compact-cars-vs-electric/ .Considering the economic condition in saving expenses.
