This is an old website, from Sempra Energy utilities but it really hits the head on the nail for accuracy about electric vehicles.
Electric motors have very few moving parts and don’t need fluids such as engine oil, anti-freeze or transmission fluid, so they require relatively little maintenance and are far less likely to leak.
While we know that electric vehicles emit no emissions from the tailpipe. Since the emissions are generated (if at all) at the power plants, then we can even further improve our health, reduce pollution and our reliance and imported oils.
EVs also run far more quietly than their combustion-powered counterparts which enhances worker health and comfort – a smart move in an era of rising medical costs.
The overall emissions associated with using EVs are typically far less than the emissions from their combustion-powered counterparts.
Most EVs charge up at night when system wide demand for electricity is low. They tap existing generating capacity that is not fully used rather than increasing demand for new capacity.
Choosing EVs instead of combustion powered vehicles contributes to reduced dumping of engine oils into the environment and reduced U.S reliance on foreign oil.
