> Energy use for cars is substantial, a significant percentage of the energy usage of homes. If that energy use shifts from fossil fuels to home electricity supplies we'll need to substantially increase the energy delivery possible to homes.
Will it, though?
Earlier this year I had 12kW of PVC installed for about A$7k. That nets me, this time of year (3 weeks away from the winter solstice in AU) about 35kWh a day. In summer I expect an average of 50kWh / day.
A Tesla 3 standard has a 50kWh battery - providing 350 km driving range. The 75kWh long range version provides 500km range.
So worst case (winter) A$7k of residential grade panels can provide charge for 200km / day - and that's on a Tesla, which is definitely a premium EV in this part of the world. (A vanilla model 3 is A$63k - the long range version A$78k.) Add in off-peak grid charging (say A$0.10 / kW) and we're really knocking ICE out of the game.
For a lot of people, not just in the same part of the world I'm in, factoring in some panels on the roof would be a proportionally small capex delta, but make the TCO hugely more compelling.
