Currently the price of energy per mile at a Tesla Supercharger is about 1/3 to 1/2 the equivalent amount of gasoline. If you charge at home it's more like 1/4.

Currently the price of energy per mile at a Tesla Supercharger is about 1/3 to 1/2 the equivalent amount of gasoline. If you charge at home it's more like 1/4. A large fraction (probably more than half) of EV owners charge at home and rarely need a fast charger. Approximately zero ICE owners refuel at home. ICE cars must be refueled at gas stations. Demand for fast chargers will never be as high as demand for gas stations for this reason. Anybody with $10,000 can install PV panels and charge their EV at home for free forever. Fleet owners with $50,000 can charge their entire fleet for free forever. No impact on the grid with these latter options.

> Currently the price of energy per mile at a Tesla Supercharger is about 1/3 to 1/2 the equivalent amount of gasoline. Is there a citation for that? It was my understanding that fast chargers were much more expensive, but I could be wrong. > Approximately zero ICE owners refuel at home. Nor do they currently use the extra electricity needed to fuel their cars each night. Again, at scale that's going to have an effect on electricity costs. > Anybody with $10,000 can install PV panels and charge their EV at home for free forever. Edit: bonus if you have links to any youtube vids of people who have done this and are currently subsidizing the entire cost of daily commutes with solar. I don't know anything about solar and would love some citations if you have them.

  Here's one: https://www.youtube.com/watch?v=jG_yIcLlzYk https://www.youtube.com/watch?v=jG_yIcLlzYk This guy has an Aussie accent but I'm pretty sure he's talking about US dollars. His numbers look accurate to me. He's estimating $5000 for charging a long-range Model 3. I think that might be a bit optimistic so I'd stick with my original estimate of $10k. Caution: I strongly suggest you buy your PV panels from a company other than Tesla. Tesla's PV business is a bit of a clusterf*ck. Just get regular PV panels and a good inverter from a local installer. If you want to charge at night, you could either install a grid-tied system with net metering (which decreases your cost of grid power), or you could install a battery just for car-charging. In that case, the Tesla Powerwall battery is a perfectly suitable option. Tesla makes great batteries, but their PV offering is overpriced and they seem to have horrible customer service.

  "free forever" doesn't imply 100% off-grid or batteries. It could imply that you only charge your car when the sun is shining.
