The Carbon Footprint Of Electric Vehicles | Earth Wise

November 29, 2022 By EarthWise Leave a Comment

Electric vehicles are widely known to be the environmentally friendly alternative to internal combustion-based cars.   But there are skeptics who argue that EVs actually have a larger carbon footprint than nonelectric vehicles.  The argument is that the manufacturing and disposal of vehicle batteries is very carbon intensive.  They also point to the reliance on coal to produce the electricity that powers the cars.

These claims have led to multiple studies in the form of life-cycle analyses comparing the amount of greenhouse gases created by the production, use, and disposal of a battery electric vehicle to that associated with a gasoline-powered car of a similar size.

In short, the studies have found that while it is true that the production of a battery electric vehicle results in more emissions than a gasoline-powered one, this difference disappears as the vehicle is driven. 

According to a study conducted by the University of Michigan and financed by the Ford Motor Company, the emissions equation evens out in 1.4-1.5 years for sedans, 1.6-1.9 years for S.U.V.s, and about 1.6 years for pickup trucks.

Emissions from driving come from burning gas in the nonelectric vehicles and from the generation of electricity used by the battery-powered cars.  In the current average power mix across the U.S., driving an EV results in a 35% reduction in emissions.  However, it varies tremendously by location.  There are some places with very dirty power and some with very clean power.  But of the more than 3,000 counties in the U.S., only 78 end up with higher emissions from electric cars.  Of course, as the electric grid gets greener, the advantages of electric cars only become greater.

Misconceptions About Electric Cars

February 8, 2019 By EarthWise Leave a Comment

Tesla’s Model 3 was one of the best-selling cars in the United States last year, eclipsing all but a handful of sedans.  This was the first time that an electric car had that honor and is indicative of how electric cars are finally becoming mainstream.  A host of other new electric models from multiple manufacturers will be the entering the market over the next couple of years.

Despite all of this progress, there is still a great deal of misinformation about electric cars.  A new study commissioned by Volkswagen revealed some of the widespread misconceptions about the vehicles.

Some people believe that electric cars can’t be driven through puddles.  Nearly one in five people believe that electric cars slow down as the battery depletes.  Many people believe that electric cars are fundamentally less safe than gas-powered cars.

More generally, people are unaware of how far current electric cars can drive on a charge.  More and more models can go 200 and even over 300 miles between charging sessions.  People also don’t know how quickly cars can charge up either.  Fast chargers like Tesla’s Superchargers can add 200 miles worth of charge in about 20 minutes.  And people don’t know what it costs to charge electric cars.  In most places, it is only a fraction of what it costs to drive the same distance using gasoline.

Despite their limited knowledge about electric cars, the 2,000 people surveyed in Britain were positively disposed towards them with nearly 6 in 10 saying that they would like to own an electric car some day and would even consider one as their next vehicle.

Electric cars will become more familiar and less exotic as more and more of them are on our roads and highways.
