Crunch­ing elec­tric car num­bers

The Intelligencer (Belleville) - - OPINION -

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
