{{hdr/myth|Electric vehicles (EVs) cause as much or more pollution than petrol-only cars.}}
==Myth==
===Example===
* '''2015-07-01''' [http://www.huffingtonpost.com/2015/07/01/electric-vehicles-pollution_n_7708406.html Here's Where Electric Vehicles Actually Cause More Pollution Than Gas Cars]: "The EV that caused no environmental damage on the road during the day still needs to be charged at night. This requires a great deal of electricity generated by a power plant somewhere, and if that power plant runs on coal, it’s not hard to imagine it spewing more emissions from a smokestack than a comparable gas car coughed up from a tailpipe." (reporting on the June 2015 NBER study)
===Origins===
While this myth had surfaced earlier, it was given a major boost by a [http://www.nber.org/papers/w21291 study] by the {{l/sw|National Bureau of Economic Research}} released in June 2015.

==Reality==
This argument basically holds electric vehicles solely responsible for the pollution of their electricity sources, as if those didn't ''also'' need to be made more sustainable. Nobody denies that EVs cause pollution if they are charged using polluting sources; this is pretty much inevitable &ndash; although it should be noted that electric motors are ''more efficient'' at converting energy to torque than <abbr title="internal combustion, i.e. petrol">IC</abbr> engines are, so it's not a foregone conclusion that they pollute ''just as badly'' when drawing on polluting sources.
===Points to Consider===
* EVs are ''neutral'' as to their energy source &ndash; unlike <abbr title="hydrocarbon, i.e. petrol (internal combustion) and diesel">HC</abbr>-powered vehicles, which depend on fossil fuels or synthetics (currently expensive, rare, and inefficient).
* HC fuel itself needs to be transported in ''other'' vehicles (tanker trucks), generating still more pollution, while electric power transmission is quite efficient by comparison.
* Many EV owners have solar panels at home which they use to charge their vehicles &ndash; creating essentially zero pollution &ndash; so even in an area that is powered by fossil fuels, you can't assume that any given EV is polluting vicariously.
* EVs tend to recharge (i.e. use power) at night, when there is surplus capacity.

EVs are not the ''whole'' solution to sustainable transportation, but they are an essential ''part.'' Barring new fuel technology (cheap synthetics, some manageable form of hydrogen, etc.), '''you can't have sustainable transportation without electric vehicles.'''
