CA, NY, MA and other states have had Zero - Emission Vehicle programs since the early 1990s because battery electric vehicles in those states, taking into account power plants, are far
cleaner than gasoline cars in reducing urban air pollution and smog.
That said, it is true that older diesel cars do pollute
more than gasoline cars, because they don't have DPFs, and diesel cars in general emit far more nitrogen oxides, which cause smog and acid rain, the study also noted.
For example, when the electric car and it battery technology have matured and become
cheaper than the gasoline car, everybody and their dog will jump on the bandwagon and try to cash in.
Specifically, I've been struck by studies (and hyperbolic headlines) that claim that EVs can cause more
pollution than gasoline cars, depending on the grid's energy mix at any given location.
If the LEAF is charged from a coal plant, it might not be much
better than a gasoline car (and maybe even worse if it's a very old and inefficient coal plant), but if it's charged from wind, solar, hydro, nuclear, etc, the impact from each mile driven could be extremely small.
In particular, because of the mechanical and structural simplicity of the EV, which have many fewer
components than their gasoline car counterparts, offer greater opportunities for achieving commonality in vehicle platforms and components, as well as manufacturing processes.
Tesla was founded in 2003 by a group of engineers who wanted to prove that people didn't need to compromise to drive electric — that electric vehicles can be better, quicker and more fun to
drive than gasoline cars.
Combined with battery swapping stations AND charging pods in every street, this combination will insure that electric car drivers will go to the battery swapping stations less
often than gasoline car drivers go to gas stations.
California Air Resources Board studies show that battery electric vehicles emit at least 67 % lower greenhouse
gases than gasoline cars — even more assuming renewables.
Also, you will find that refueling is actually
faster than gasoline cars - only taking about three minutes from start to stop.
EVs powered by the grid currently produce 54 percent less (lifetime) carbon
pollution than gasoline cars, which could grow to 71 percent by 2050 as our power supply gets cleaner.
If the LEAF is charged from a coal plant, it might not be much
better than a gasoline car (and maybe even worse if it's a very old and inefficient coal plant).
The world's biggest car maker won't say when it would begin mass - producing the vehicles, but Burns said that if 500,000 to 1 million were built, they would «cost no
more than a gasoline car.»
Those that run on California's electricity are two - thirds cleaner
than gasoline cars.
With no tailpipe emissions, these vehicles can be up to 99 % cleaner
than gasoline cars, even when power plant emissions are included.
