Since the U.S. became a net exporter of petroleum, how do EVs improve U.S. fuel security?

The transportation sector still accounts for about 66% of U.S. petroleum consumption and because the U.S. imports and exports oil, it is still subject to highly volatile global markets. Since EVs don’t use gasoline, they reduce U.S. dependence on fossil fuels. Plugging into the U.S. grid diversifies U.S. transportation energy to renewables and other domestic sources. This protects markets from embargoes, shortages, and political conflicts. It also protects drivers from price volatility at the pump.
