Industry sources are confident that they can handle the demands of the upcoming release of plug in hybrid vehicles by the major manufacturers. They are confident because they went through a similar mini evening surge in demand once Plasma TVs became common.

"We've already added to the grid the equivalent of several years' production of plug-in hybrids," Duvall said at a conference on electric vehicles in San Jose. "The utilities, they stuck with it. They said, 'All right, that's what's happening. This is where the loads are going, and we're going to do this."' ed.z.: It will sure help if employers and municipalities start to work on charging stations for cars at parking spaces and lots.

I bought a new TV about six months ago. I asked about power consumption and the salesman insisted that an LCD TV will use more power than Plasma TV. I bought the LCD anyway but it left me wondering about the way they use power.

I have a desktop image from the hubble telescope with a bright star in the field and whenever it comes up I have to put a window on top of that star because it is too bright to look at. LC displays work by filtering out light from a bright backlight so the whole display is pumping out the maximum amount of light all the time.

CRT and Plasma displays drive their output up and down depending on the amount of light needed so they should consume less power for a dark image.

So what uses more power? LCD or Plasma?

I tought LCD used less power than CRT, if plasma TV use less than CRT when CRT TVs are replaced by plasma TVs should it not take less power that before? confused ...

We need a sense of proportion here. A typical plasma screen is rated to consume 300W peak. Of course the power grid doesn't even flinch. (An oven or clothes dryer takes ten times that, and a plug-in car is bound to be more yet.)

Now that oil heat is more expensive than just wasting electricity, we'll likely see some much larger than 300 W spikes in electricity usage, too.
