Well, I cannot defend many hybrid technology vehicles because they still ultimately run on gasoline. Pure electric vehicles are another story.
Ozzie Zehner simply makes the same mistakes (or purposely overlooks the same facts) as other electric car critics. Here's the most important of them:
1) Gasoline cannot ever be cleaner than electric cars because gasoline also needs electricity! Huge amounts of electricity and other fossil energy is used to refine oil into gasoline. The US Energy Information Administration estimates around 6 kilowatt-hours for every gallon refined. An electric car could drive 20 to 30 miles just on that wasted refining energy, without even burning a drop of the oil.
At least EVs don't burn a side of oil with their electricity!
2) Electric cars are far more energy efficient. This is obvious just from looking at the energy costs per mile. Electricity for EVs costs 2 to 4 cents per mile. Gasoline costs much more, 15 to 30 cents per mile, because most of gasoline's energy is simply wasted as heat in a typical gas engine.
Greater efficiency means more miles driven on less fuel, and therefore far less pollution per mile, no matter what fuel has been burned.
3) The only energy source on the electric grid dirtier than gasoline is coal, and most EV critics compare gasoline only against coal power. But this argument is out of date - the grid is no longer mostly coal power. Last year (2012) coal hit a low of just 32% of the grid, and coal is slowly on the way out. Every other source of electricity - most of the grid - is much, much cleaner than gasoline, and the grid gets cleaner every year.
