The good thing about electricity is that you can diversivy the source of energy, unlike gasoline where oil is the only choice, electricity can come from nuclear, coal, natural gas, hydro, wind, solar, biofuels... We aren't trapped on the petroleum treadmill if we use electric vehicles. A lot of the folks that leased the early EVs are hardcore environmentalists and already have big solar arrays on their roof that run their home, charge their car and put power back on the grid, so it's not unreasonable to expect a certain percent of people to do the same and become energy independent.

Not to mention that EVs are 5-10x more efficient in their use of energy than an ICE based vehicle (hence the reason they use electric drivetrains in hybrids).
