Last night, I posted a simple calculation to Twitter. Based on gasoline energy content of 32.2 MJ/l LHV, and a conversion of 3.6 MJ/kWh, I calculated 8.94 kWh/l of gasoline, and thus stated that $1.30/l gasoline was approximately equivalent to 14.4c/kWh electricity. This had, in a sense, the desired result. Many of my followers followed up with questions on my assumptions and provided alternative calculations, so I thought I would open this space and allow them to do so in more than 140 characters.
So, here’s the question. At $1.30 per liter gasoline, take us through the decision of Leaf vs. Corolla or similar. What’s the break-even price of electricity if gas is$1.30/l (the price we paid yesterday in BC)? At 14c/kWh electricity delivered to your home, assuming you have a 30amp feed to your garage for a charger, what’s the NPV of an electric car at $1.30/l gas?
Thanks for your contributions!
