Ever since electric vehicles (EVs) became a viable alternative to traditional gasoline cars, there has been a push to make them greener. Rather than fueling EVs with electricity from the grid -- which is powered mostly by coal and natural gas -- nearly every major EV maker has a partnership to pair their vehicles with rooftop solar energy. Tesla (NASDAQ: TSLA) even bought SolarCity to make the integration of solar and EVs seamless.
Ultimately, the goal will be for EVs to generate some of their power themselves. Yes, the sun could provide electricity that could power your vehicle -- and solar cars may be closer than you think.
