Research question: how do electric cars affect air environment?
Barry Saxifrage, who consistently researches and writes about climate changes for the Vancover Observer and other publications, argues that generally electric cars cause less or equal climate pollution than gasoline cars. To support his claim, the author analyzes data from energy databases and industry websites on pollution released by producing the cars and batteries, burning gasoline, and generating the electricity as the vehicle’s fuel, drawing a chart to vividly compare the climate impacts of all electric, plug-in hybrid and all gasoline cars. According to the chart, the author concludes that in most regions such as Ontario and California where most of the electricity comes …show more content…
First, the author questions the motive of electric cars’ producers that they tries to convince their customers that electric vehicles cause less pollution to sell their products and thus make profits. Then, he employs a study on the life cycle of car emissions which “estimate how levels of fine particular matter and ground-level ozone-two important constituents of air pollution would change if each of 11 ways of powering a car were to be responsible for 10% of the vehicle-miles expected to be driven in America in 2020” researched by Christopher Tessum, Jason Hill and Julian Marshall of the University of Minnesota to illustrate his claim. The result of the study shows that electric cars equipped with renewable electricity are responsible for 231 deaths and power from natural-gas-fired stations are 439 deaths per year, while the deaths caused by gasoline cars are 878. However, the vehicles recharged by electricity from coal can lead to over 3,000 deaths. The purpose of the author is probably to contradicts the general belief that electric cars are cleaner than petrol …show more content…
To back up his opinion, he uses the study anticipating the influence of electric cars in the US to 2050 published in the journal Environmental Science and Technology [Samaneh Babaee, Ajay S.Nagpure, and Joseph F. DeCarolis]suggest that whether electric cars improve air quality depends on many factors such as whether their ultimate fuel originates from coal. Also, the answer remains uncertain because the future is unknown: we don’t know whether US will have a law regulating car emissions, whether batteries will be cheat, and whether oil or natural gas costs more. Furthermore, he mentions different computer models predicting the changes in driving patterns in a few decades ran by researchers to support that regulations on decreasing CO2 and other pollutants matter more than increasing the number of electric cars. What might stimulates Biello make this report is that Tesla plans to sell its Model S (a supposedly zero-emissions vehicle but actually not in Biello perspective) in
