Not So Fast, Einstein

In an article by Yuri Kageyama (AP Business/Yahoo! News, Nissan rolls out electric car at new headquarters, August 2, 2009):
"This car represents a real breakthrough," Ghosn told reporters and guests at a showroom in the new headquarters.

He said the new car and new office building in Yokohama, southwest of Tokyo, marked two fresh starts for Nissan, which hopes to take the lead in zero-emission vehicles.

Has the world gone completely nuts?  The car may be zero-emissions, but producing the electricity needed for it to run produces all sorts of emissions, depending on how the electricity is produced.

We have emissions from creating energy (in a gas-powered car the emissions are created when the car is driven, in electric-powered cars the emissions are created when the energy is produced).  The fact that the energy needed for this car to run is emitted before it is used in the car, doesn't mean that the car has the net result of being "zero-emission."

This is propaganda at its finest. The debate will continue about how to produce electricity (and how to produce more electricity as the need for it rises, especially if we are producing and buying cars that need electricity to run). In general, however, distributive processing is a better idea. All the combustion engine cars on the road are producing the energy they need, and are not reliant on the strained power grid. Increasing the demand on the power grid will require considerable investment, as well as produce emissions in its overhaul, and the fuel source that runs it.

If an electrical plant runs on gasoline (or fossil fuels) or coal, and a car uses the power it produces to run, is the car really zero-emission?

Of course not!  It seems that the concept of "net effect" is lost on most people.
