Crunching electric car numbers
In a recent letter to the editor, it was stated that “it takes two kilowatt hours to produce one litre of gasoline.” And recently it was published that the 2019 Audi e- tron all- electric SUV full battery storage holds 95 kilowatt hours of electricity that will drive the vehicle 400 kilometres.
Now current gasoline cars ( city and highway) average approximately nine litres per 100 kilometres. So a gasoline vehicle would use 36 litres per 400 kilometres, and multiplying that with two kilowatt- hours per litre of gasoline, only 72 equivalent kilowatt hours would be used to drive 400 kilometres. However, this by far is not an accurate scientific analysis.
My objective is to develop a constructive conversation on this topic and encourage the scientific community to study this subject as global warming harm moves in on us. Proper study results would provide valuable information where improvements could make the electric car the best way to go. This is not a subject limited to just Canada and Ontario, with its solar farms and wind turbines. Electric cars are being globally encouraged as a means to limit global warming, while the U. S. still has approximately 50 per cent of its electricity produced by fossil- fuelled generating plants, and
China about 90 per cent. Mel Grandame Kingston
