The batteries in electric vehicles, for example, charge on power that is coming straight off the electric grid which is itself often powered by fossil fuels. And there are questions about how energy-intensive it is to build an EV or an EV battery, versus building a comparable traditional vehicle.
Are electric vehicles greener?
The short answer is yes but their full green potential is still many years away.
Experts broadly agree that electric vehicles create a lower carbon footprint over the course of their lifetime than do cars and trucks that use traditional, internal combustion engines.
Electricity grids in most of the world are still powered by fossil fuels such as coal or oil, and EVs depend on that energy to get charged. Separately, EV battery production remains an energy-intensive process.
