Yes. Most car batteries are about 60kwh. If you werenāt horsing the thermostat up to 21 that would power a house for a few days. Not all cars have the ability to feed back to the house so worth checking when buying a car with that in mind.
If someone has an EV and with an impending storm comimg, Iām sure that they would charge it up prior to the storm and potential outages. I doubt theyād leave it at absolute zero. So for the potential couple of days maximum without power, Iām sure theyād manage whatever necessary driving is required during a storm where people are told to stay off the roads in any case. Similarly, a house heated by a heat pump wouldnt have a major drop off in heat for 3 or 4 days, if that. And those with either solar or an ev could utilise both of them to keep the house electrics going for the period of the outage.
It always seems that people want to be so against new technology or different ways of doing it without actually knowing what could be done or what the practicalities of the different ways are in real life.
Thereās obviously an element of ball-hopping to my point but I think, with the drive to have more and more of peopleās lives (and heating and transport are critical to peopleās lives) dependent on electricity, we need to ensure that the network is robust enough to handle that. What you say regarding making sure the car is charged and the house is insulated properly makes sense it may not be possible for people, especially vulnerable people who live at home alone or in a rural area.
With storms like the one we just saw predicted to become more and more common, we need to ensure that the switch to fully electric doesnāt leave people stuck. An ICE car is better for an emergency trip. A stove is better when the power goes.
