I remain fascinated by the electric vehicle discussions and of course, the battery developments are very relevant to eCook. I saw this interesting discussion about a Tesla.
How much fuel does it cost to drive 1 mile. In a Tesla this is a kilo Watt hour kWh. A Tesla Model 3 battery holds either 60 or 75 kWh and can drive for 252 or 316 respectively. Fuel/Miles = .237 kWh/mile. That’s about the same as an Irish stew in a multicooker. An Irish stew per mile.
The writer, Carroll Lee, on Quora, then found (in 2016) the gasoline and electric prices, albeit for her home of Arkansas @ $0.098 cent per kWh and $2.631 per gallon. She compared with a BMW doing 33 miles to the gallon, giving Arkansas Electric .098 * .237 = 2.3 cent per mile, Arkansas gasoline 2.631 / 33 = 7.97 cent per mile. You can of course get cheaper electricity at night, and more expensive electricity in other states – but even in Massachusetts, she had Electric .2063 * .237 =4.9 cent per mile and Massachusetts gasoline 2.853 /33 = 8.64 cent per mile.
Makes carbon sense and save US cents.
(Ok neglecting the Capex and the O&M costs!)
