Myth 2: Plug-in cars will lead to the production of more coal and nuclear plants.
Reality: Even if the majority of drivers switched to electric, the existing electrical grid's off-peak/nighttime capacity for power generation is sufficient without building a single new power plant. Studies have shown that electric vehicle owners will largely charge their vehicles at night when there is plenty of capacity on the grid. In some areas, new "smart charging" allows you and the utility to set up a system by which you and other electricity users distribute the load evenly during charging so that the system is not overwhelmed by increased demand.
