Lack of enough electrical resources

The argument

Electric vehicles require large quantities of electricity, so lots of electric vehicles would strain the power grid. If a few electric vehicles were suddenly charging, the increase in demand for electricity could cause the surrounding area to experience electrical shortages. As a result, if everyone had an electric vehicle, there would not be enough power to charge all of those cars. In order to combat this problem, the infrastructure of the electrical grid needs to be updated. This would require massive infrastructure changes, so it is unlikely to happen on a large scale. Most power grids are set up in a way that accounts for the lower electricity use at night while people are asleep. Electric vehicles would conflict with this schedule. Most people would charge them at night--straining the grid when it is at it's lowest.

Premises

Counter-arguments

There is enough electricity in the system to charge a large number of electric vehicles. It is possible that if everyone were to plug in their cars at the same time, during peak hours of electrical use, there could be a shortage. However, that is unlikely to happen. People who buy electric vehicles can be informed about when they ought to charge their cars, and some states have started point systems to encourage people to charge their cars at specific times.

Rejecting the premises

[Rejecting P1] The premise conflates local distribution capacity with national generation. Clustered fast charging can strain a particular substation, which is a question of local network reinforcement handled routinely as demand changes; full fleet electrification is generally estimated to raise total electricity demand by a fraction of current generation, phased in over decades as vehicles are replaced. [Rejecting P2] This premise has the position exactly backwards. Overnight is the demand trough, not the point at which a grid is weakest — generation capacity sits idle then, which is why off-peak charging fills a valley rather than adding to a peak, and why tariffs are designed to push charging into those hours. Vehicles connected overnight can also be managed as flexible load, and increasingly returned to the network. [Rejecting P3] Grids are continuously rebuilt rather than replaced in a single undertaking, and the investment required is spread across the same decades as the vehicle turnover. The counter-argument on record makes the practical version of this point, noting that time-of-use pricing and incentive schemes already shape when people charge. [Rejecting C] The premises would at most show that electrification requires network planning, which every position in this debate accepts. That is a constraint on the pace rather than a reason it will not happen at scale.
