A new study says electric cars produce fewer global warming emissions than hybrids - in some regions.
The Union of Concerned Scientists says electricity in California and New York isn't as reliant on older, coal-burning power plants as other regions.
"Driving an electric vehicle in those areas has lower global warming emissions than even the best, most fuel efficient hybrid gasoline vehicles that are currently on the market."
Don Anair wrote the report. He says in other regions, electric cars are at least as clean as the most fuel-efficient regular cars. But other studies predict low consumer demand for electric cars for a long time, because they can’t go that far before they have to be recharged, and they cost more.
