I think it will be important as we transition to EVs to have more energy available. In Ontario, the typical family home uses something like 750 kWh/month on average. If you estimate 5km/kWh (roughly right?), and presume a car is driving something like 1000 km/month, that's an extra 200 kWh/month needed, about a 25% increase. But in the less developed parts of the world, a car might just be a much larger component of personal energy use- perhaps most of it.
