Totally agree with BigTuna. You do not NEED fast recharges. You do not NEED 500 mile ranges. My household has 2 cars and 1 person that commutes. So for awhile I suspect we will have 1 ev and 1 phev or hev (like keep our HCH).

Of course - recharging fast during the day would be nice - a luxury. Guess what - in capitalism we have a way of having a luxury - it is called $$$. Cheapest option - plug in at home at night, more expensive - charge during the day....

Full (by full, I mean probably 80%) penetration of EVs will take 30 years - and we are talking about the grid today. I am guessing the grid 30 years ago could not support a/c in every home that we have today - I bet there was a lot of panic about that back in 1978.... I hope we don't expect the grid to look the same in 30 years.

The thing about all this bs about daytime peak usage and ev's may be all hoopla if solar becomes cheap and efficient. Then - we will have so much daytime power that we won't know what to do with it.

To whoever posted that they use 100 kwh a month - great. But look at average US household electricity consumption 10,600. So 800+ a month. If you can go 5 miles per KWH and 40 is the magic mileage - then 8 kwh/day, 240/month. That requires a 30% reduction in use to keep at the same usage. You can get 30% for an average household with current efficient technologies that will get phased in over the next 10-15 years. Between CFLs, efficient fridges and A/C, better insulation - you will get there. The CFLs and more efficient appliances are already mandated and will happen without any new changes - over time but will happen.

Mind you - those numbers are for 100% penetration but they also are for Prius like vehicles. No population increase, no increased usage. So you definitely need more grid generating capacity over 30 years - big surprise.
