On the contrary, a couple of notes from a real electric car owner:
You can charge it at home overnight. You can set the time it begins to charge for a non-peak hour. In this way you are actually being beneficial - it takes time to start and stop a power plant and you are helping to provide a steady base load when the only demands to the power grid are lights and people heating their homes. A steady base load is beneficial and you are also defraying the peak demand during the hours when everyone is awake.
The batteries in some electric cars can actually be used as storage devices and can backfeed the grid during periods of peak demand. The grid provides instantaneous power but it does not store energy very well. Teslas in particular have this ability. So instead of having to brown out the grid or have rolling blackouts (or buy power at vastly inflated rates such as during the Enron scandal), they can draw power out of fully charged Teslas that are plugged in, and keep the grid going. Tesla also makes a device called an Energy Wall which is a big battery pack you have in your garage, which can be charged with solar or grid power during off-peak hours. It can also be used to backfeed the grid. It was used to rescue a large area of Australia which was having power shortages during peak hours. Not any more.
People should do real research and use critical thinking skills.
Those power walls and similar are part of expanding grid capacity. Energy consumption typically peeks during the day, those batteries can even out the load, and at night when energy use is low, charge up.
Typical plans will have a high day time price, you can sell power to, and low price at night you can buy.
