Not for long, not if the utilities get their say. For example: http://srprevealed.com/ The short version: Salt River Project is poised to make solar customers pay just about what they'd pay if they didn't have any panels on their roofs in the first place.

Affordable EV batteries also mean affordable off-grid solar, whether or not the batteries travel with the car. A decade from now, as many people will have a Tesla-branded black box the size of a clothes hamper sitting next to the water heater and no power meter as currently do a cellphone and no landline. It's up to the utilities to decide if they want to get in on that action...and they're currently trying to re-run the same plays as Ma Bell did. Why they want to commit suicide in that particular manner is a mystery to me, but go figure.... Cheers, b& -------------- next part -------------- A non-text attachment was scrubbed...
