I was assuming a car that cost $30K and lasted 15 years.
The parent seemed to be talking about cars in general, so I wasn't referring to Teslas in particular.
I can try this again using some different sources and methods.
- GDP of $1000 equates to about 1540 pounds CO2.[1]
- Each pound of CO2 implies about a kWh based on average power generation intensity.[2]
- Therefore, a $30K car implies 30 x 1540 or about 46,200 kWh.
- Divided by 15 years and by 365 days gives about 8.5 kWh per day.
So, I was probably off by a lot, and may still be off, but I feel like my point is intact, because 8.5 kWh still almost doubles the energy requirement originally stated. It's not negligible.
