If indeed this is as disruptive as Musk says, this will be the beginning of the end of fossil fuels and a lot of nuclear energy!

Wikipedia excerpt continued here:

Tesla Motors may have the lowest rates for electric car batteries; the estimated battery costs for Tesla Motors is around US$200 per kWh.^[96][97] Currently, Tesla Motors charges $10,000 more for the 85kWh battery than the 60kWh battery, or $400 per kWh. At $200 per kWh, the battery in the 60kWh Model S would cost $12,000, while the 85kWh battery would cost $17,000. The price increase is closer to $8,000, as supercharging is included in the higher price. It is a $2,000 option for the 60kWh version.

Commenter R. Cole has this to say:

What does the battery do? It powers your home..it saves you money rather than you pay the power company every month as I’m sure you do and last but not least..you say you it will cost you money to keep it charged…. ummm no its not….Thats what the solar panels are for. The light comes from the sun which doesnt cost you a brown penny. The panels keep the battery charged which has enough power to run your home. This is what power companies dont want you to know.. this is what the news media and negative ppl against solar want you to think..This is where you do your own homework instead of following what others THINK they know. No offense but this is the best thing to come about.

Only time will tell but this seems like a possible game changer!
