Sierra Club pushes electric vehicles – Chicago Tribune

The Sierra Club’s EV Guide uses the EPA’s national electricity grid to calculate emissions by region. The region encompassing Chicago and West Virginia uses 69.9 percent of coal-powered electricity. The national average is 44.5 percent. (EPA)

The Sierra Club got on the emission-free electric vehicle bandwagon last month by launching its Electric Vehicle Guide. The guide features the typical range, price, MPGe and carbon- and cost-saving metrics. The blog section will report positive news, says Jesse Prentice-Dunn, a transportation policy analyst for Sierra Club. “We’ll be publicizing success stories of communities going electric and doing what they can to reduce their dependence on oil,” Prentice-Dunn says.

One of the more interesting components of the site is the state index. Entering your zip code will turn up your annual oil savings, CO2 emission savings, and state incentives from rebates to reduced vehicle registration fees. The oil and CO2 savings are based on the EPA’s national breakdown of 26 electrical grids and the estimated emissions in each of those grids. Numbers were last calculated in 2009.

“This does take into account the full lifecycle emissions of the electricity generated to power the EV, based on the region you’re in,” Prentice-Dunn explains.
