Well, when the zombie apocalypse happens relying on the grid is unsustainable.
But in reality, there are also transmission losses (which I think are actually quite small when you have high voltage) when you produce energy away from where you use it.
- abalone 10y agoThere are also losses from battery charging. I haven't researched thoroughly but some Tesla fan discussion thread puts it at 20-30%[1], which would be vastly higher than transmission losses. Especially since the electricity typically wouldn't have to travel very far at all before it's used.

- sowbug 10y agoThat's the Roadster from 2011. The Model S is more than 90% efficient (https://www.teslamotors.com/support/model-s-specifications https://www.teslamotors.com/support/model-s-specifications).
- dvdkhlng 10y agoI think most of the losses are due to the cost of building and maintaining transmission lines. These have to be paid for by users of the power grid. In Germany these transmission costs constitute about 20% of the total end-user price per kWH (i.e. about 5 cent/kWh).
