THANKS! Well, THAT'LL certainly 'clean up' the other discussion....

The global demand for PV panels is far outstripping manufacturing capacity and these subsidies are only agravating the situation. The result is that over the last 2 years the cost per watt has actually increased. The positive side is that manufacturers are increasing capacity at a rapid pace but this might have occurred even with slightly lower subsidies. The comment that millions of EV owners charging their batteries is going to overtax the grid is unfounded. For one thing it will probably take at least 10 years for there to even be 1 million EVs on the road. Also, the people that operate our nation's electricity grid welcome these vehicles. I don't pretend to understand how this works but apparently it creates the potential for load levelling, which has a positive impact. Not to mention your vehicle can now be an emergency back-up power supply for your home.

Also, are the PV systems being installed supposed to fill all of that homeowners needs (regular domestic use + EV) or just reduce daytime demand on the power grid. "Also, the people that operate our nation's electricity grid welcome these vehicles." I think I can understand this. Most recharging of EV's would occur at night. Typically, the demand to the system is currently much lower at night than during the day (when AC systems are running full blast, businesses are operating, etc.). Under the current system, the power plants are constantly cycling up during the day to meet the higher demands and then cycling back down to a reduced level to meet the lower nightime demands. Perhaps the plants don't operate as efficiently as they cycle up and down? Hadn't considered the possibility of using the EV as a back-up power supply for the house.

Whether or not that ends up being the case it is positive to see government programs that aren't designed to last indefinitely.

| Isn't there any plan in place (or being proposed) that would require the replacement (or clean up) of the old "dirty" coal plants? It seems that both the reduction of the use of gas and emissions are critical and need to occur quickly! | |
Yes, this is a more general electric vehicle topic, but let's keep this autiomotive related and not go off into the various ways that electricity are generated and forget about the cars please.

Replying to: prm2000 (Aug 08, 2006 7:00 pm) I'd say my biggest concern regarding the Tesla and all the other EVs is how these new Li-ion batteries will hold up. I know they've done extensive testing regarding safety and number of cycles but what about aging? My understanding is that Li-ion batteries lose storage capacity purely as a function of time, regardless of whether they are even being used. I'm not sure how well you can test this in the lab and I haven't read of any breakthroughs along these lines. If the Tesla, which is advertised at 250 miles per charge, can only get 150 miles per charge after 3 years I suspect there will be some unhappy owners. I hope this doesn't turn out to be the case but I think that only time will tell.

Replying to: pf_flyer (Aug 09, 2006 3:27 am) If we can't talk about how the electricity is generated in an EV car discussion, where CAN we talk about it? Are you saying that one simply CAN'T talk about electrical production ANYWHERE ON EDMUNDS?
