What will all the tree hugging envinromental activitists EV lovers do when there is no electricity to charge their zero emissions vehicle? According to the short piece below, from Automative Magazine, as few as 3 EV's in one neighborhood will overload the grid. --------------------------------------------------------------------- Could electric vehicles and plug-in hybrids tax our existing power grid to the point of failure? According to Peter Darbee, CEO of the Pacific Gas & Electric Corporation, the answer is yes. As few as 3 EVs in a single neighborhood could "overwhelm the circuits." According to Darbee, a single vehicle drawing power from a 220-volt outlet is akin to adding another house to the grid. Darbee also expects EV owners to plug in at similar times, especially if they're returning home during typical rush hours. "You would create a peak load on top of the peak load," he said. "What happens if three to five vehicles show up in one neighborhood? You're going to overwhelm the circuits."

And not many people are going to have an "extra" 220 volt plug in the garage - most have 1, and their dryer is using it. Automakers will provide us with 110 V charging cars. 2. Like anything else new, early adopters will have to be "trained" to plug their cars in later in the evening, rather than when they first get home. 3. Automakers are already planning for this: Ford's new vehicle-to-grid software program allows the driver to "to accept a charge only during off-peak hours between midnight and 6 a.m. when electricity rates are cheaper, or when the grid is using only renewable energy such as wind or solar power." So not only could you minimize your electricity costs by charging only when its least expensive, but you could also minimize your CO2 emissions (if you don't already get 100% of your electricity from green power, that is). 4. There already pilot systems in place where the electric cars FEED BACK INTO THE GRID during peak hours, then start re-charging themselves after peak hours. 5. The main thing is that electric cars will NOT "boom" immediately upon the release of the first vehicles. The grid, software, and battery hardware will have time to "catch up" before the number of electric or PHEV cars reaches critical mass in regard to the grid. They are not going to sell a million cars the first year. If they sell 50,000 over the first year or two I would be surprised. Worry not your pretty little heads about electric cars overwhelming the grid. That ain't gonna happen. "I got 99 problems and the grid ain't one."

I don't see anybody posting on the kia sorento diesel hybrid, that was at the 2009 frankfurt auto show. It is now being road tested in europe. I have a question for anybody who can answer. What's the difference between euro-v diesel passenger car standards and the eqiuvalent u.s. epa standards? ie ppm, co. so2, and so on. How much difference is there that keeps their diesels from meeting our govt's standards. By all means, read between the lines.
