Something I've been missing in this discussion is a notion of scale.
This is a statistic from 10 years ago from the US:
- the average citizen uses 10 times more energy when going from and to work each day (the use of their car) than all their energy use of the rest of the day combined.
If I'm not mistake, this includes natural gas.
Now this number has shifted in the past 10 years.
But let's say a batterypack for the average home is about quarter the size of what goes into a car.
Also what would happen at homes when electrical cars are driving down the price of batteries ?
What if you life in a country where power from the grid has a different price for night than day ?
Well, that system isn't going to last is it ?
Will it smooth out demand on the grid during the day ?
Lots of changes coming in the future, they could be bad, they could be good. They will be bad for some people, good for others.
I do know one thing Elon Musk will probably make some more money if he can deliver on some of his goals.
