Eco-friendly cars kinder to some cities

The following graphic summarizes the story of electric vehicles (EVs) and their true contribution to the reduction of greenhouse gases. It makes the point that since an electric car requires charging through the local electric grid, the source of that electricity greatly influences the overall carbon footprint of driving. However, a report from the Union of Concerned Scientists shows that “in every part of the country, EVs outperform most gasoline-powered vehicles when it comes to global warming emissions.”

More from the Union of Concerned Scientists:

While the environmental benefits of driving an EV vary depending on where the driver charges the EV, electric grids across the country are getting cleaner. In fact, 29 states and the District of Columbia are implementing renewable electricity standards while a greater number of older and dirtier coal plants are retired.

“The good news is that as the nation’s electric grids get cleaner, consumers who buy an EV today can expect to see their car’s emissions go down over the lifetime of the vehicle,” said Anair.

Wherever EV owners charge their vehicles, they will also save money. Based on electricity rates in 50 cities across the United States, the analysis found drivers can save $750 to $1,200 dollars a year compared to operating an average new compact gasoline vehicle (27 mpg) fueled with gasoline at $3.50 per gallon. Higher gas prices would mean even greater EV fuel cost savings. For each 50 cent increase in gas prices, an EV driver can expect save an extra $200 a year.

Maine is fortunate to be on the cleaner end of the scale with very little electricity sourced from coal-fired power plants. According to the U.S. Energy Information Administration (EIA)

  • Maine had the lowest average electricity retail prices in New England at the end of 2011.
  • In 2011, half of Maine’s net electricity generation came from renewable energy resources, with 25 percent from hydroelectricity, 21 percent from wood, and 4.5 percent from wind.
