EVs make it easier to manage the grid - the challenges are in local distribution. The vast majority of EV charges are overnight, because that's when electricity is cheap, because that's when we have more supply than demand. Most generation sources can't be quickly switched on and off; renewables generate whenever the sun is shining or the wind is blowing. EVs help to balance the grid simply by sucking up lots of off-peak capacity. The next generation of cars and charging points are expected to support vehicle-to-grid technology; in exchange for a reduction in your cost of charging, you allow your car to be used as a grid storage battery when you're not using it. A few million cars with 40kWh batteries add up to a very big storage reserve, even if you only take a couple of percent from each car. https://en.wikipedia.org/wiki/Vehicle-to-grid https://en.wikipedia.org/wiki/Vehicle-to-grid
