Utility company backs plug-in hybrid vehicles

So, now California's largest utility company is getting on the plug-in hybrid bandwagon (more)? And why not? It's just more business for the utility companies, right? Maybe, maybe not.

An even more important issue for many; however, is whether electricity is cleaner than gasoline?

On the face of it, maybe not, but that isn't the real point. The point is, today, hybrid cars are more efficient than conventional vehicles due to technologies such as regenerative breaking which creates electricity stored in batteries. This electricity can be used to fully power some hybrids at lower speeds, such as in the daily slow-and-go commutes of the average urbanite.

And that's where plug-in technology comes in.

Effective plug-in hybrid vehicles will need new battery technology, such as lithium-ion technology. Lithium batteries could increase the efficiency capabilities of hybrids, enabling them to act almost as electric vehicles. Still, if battery power isn't sufficient, gasoline is always available as a backup.

But let's get back to the clean energy debate. Next generation hybrid technology and software, coupled with next generation batteries, means that hybrids can generate even more of their own electricity. Consequently, the vehicle doesn't have to plug-in for all of its fuel - just to top off the batteries. Eventually, this model could even incorporate a small fuel cell, which would make the vehicle even far more efficient.

Already, labs such as Argonne, have studied the clean energy debate and their studies indicate that plug-in hybrids - ALL THINGS CONSIDERED - are cleaner than gasoline powered vehicles. Moreover, over time plug-in hybrids will achieve greater and greater efficiency.

Oh yeah, and we could end foreign oil dependency. Even if plug-in hybrids were ONLY as clean as gasoline vehicles, wouldn't ending foreign oil dependency still make them worth it?
