State of Charge: Electric Vehicles’ Global Warming Emissions and Fuel-Cost Savings Across the United States
"Electric cars produce lower global warming emissions and cost significantly less to fuel than the average compact gasoline-powered vehicle."
"The UCS report, State of Charge: Electric Vehicles' Global Warming Emissions and Fuel-Cost Savings Across the United States, compares the global warming emissions from EVs with those from gasoline-powered vehicles and finds that:
*Nationwide, EVs charged from the electricity grid produce lower global warming emissions than the average compact gasoline-powered vehicle (with a fuel economy of 27 miles per gallon)—even when the electricity is produced primarily from coal in regions with the “dirtiest” electricity grids.
*In regions with the “cleanest” electricity grids, EVs produce lower global warming emissions than even the most fuel-efficient hybrids.
*EVs charged entirely from renewable sources like wind and solar power produce virtually no global warming emissions."
"The report compares charging costs in 50 major cities across the United States and finds that:
*On the best rate plans, electric vehicles can save $750 - $1,200 a year on fueling costs compared to a gasoline vehicle averaging 27 miles per gallon and fueled at $3.50 per gallon.
*EV owners can save money on fueling costs without changing electricity plans, but taking advantage of rate plans that offer lower-cost electricity at night (“time-of-use” plans) can mean hundreds of dollars in additional savings per year, especially in California.
