More good news about electric cars in the U.S.: the emissions associated with the electricity used to charge them have fallen. Again. Based on the latest data on powerplant emissions from the EPA, an electric car on the road in the U.S. now has average emissions as low as an 80-mpg car. DON'T MISS: Electric cars cleaner than any gas-only car for... Electric cars got even cleaner in a year, new grid data shows

When electric cars first arrived in 2011, it was a reasonable question: Aren't you just shifting emissions from the tailpipe to the smokestack? The answer is yes, but the carbon emissions per mile of an electric car—properly measured on a wells-to-wheels basis—are virtually always lower than those of a gasoline or diesel car. It's not... 
Mazda is a tiny carmaker on a global scale, producing just 1.6 million vehicles a year. It competes with four companies (GM, Nissan-Renault, Toyota, and VW Group) that each sell around 10 million a year, as well as numerous other smaller makers still larger than Mazda. In a world where reducing the carbon emissions from road vehicles is... ![Electric cars dominate U.S. climate-friendly vehicles [data: U.S. EIA; map: Climate Central]](http://images.hgmsites.net/tmb/electric-cars-dominate-u-s-climate-friendly-vehicles-data-u-s-eia-map-climate-central_100608171_t.gif)
The question is a reasonable one: electric cars may be zero-emission, but what about the electricity to recharge them? While renewable energy is growing globally, burning fossil fuels is still the source of most electric power today. The good news is that in most areas of the U.S., the "wells to wheels" carbon-dioxide emissions associated with... 
It's now clear that the zero-emission vehicles of the future will be powered by electric motors. The electricity to power those motors, however, will come from one of two competing technologies: high-capacity batteries or hydrogen fuel cells. The debate over which technology is superior, which has the lowest wells-to-wheels carbon footprint, and... 
Electric cars are simply nicer and calmer to drive than conventional cars, and as their prices fall, that may be what will lure mass-market buyers over time. But they have undeniable benefit of lowering wells-to-wheels carbon emissions per mile driven, and they can also be powered entirely on renewable energy. Which makes them good for drivers and... 
Transitions into new technologies always generate confusion and misinformation, and certainly that has been the case with modern electric cars. Buyers, automakers, and analysts debate their cost, suitability, real-world range, wells-to-wheels carbon footprint, and recyclability, among other issues. Six years after the first modern electric cars...
