More vehicles that require a plug in charge will put more load and demand on the electrical grid. The electrical industry (I work in it) is taking more generation facilities off line in the interest of “eliminating carbon emissions”, and we are not building new ones to go back in their place. Taking x amounts of Megawatts in generation abilities off the grid, while simultaneously increasing the load demand by everyone having to charge cars, will cause problems and power outages. Power systems are designed to protect theirselves and breakers and units will trip when voltage gets too low/high, gets out of frequency, detects a fault, etc. When the load goes up, the voltage goes down. If there’s no generation facilities to turn the power up to keep the voltage at the correct levels, lights go off. It can cascade in extreme scenarios and effect large geographic areas and cross different electric companies.
I saw a report on Fox News today that California had told people with electrical vehicles to not travel over the holiday weekend because their grid couldn’t support the charging demand, but yet they mandate more electric vehicle purchases.
