I wish I could give you a good figure for that, but I don't have one. What I can give you is the estimate that NRCan has put forward to build the public charging network that it thinks we need, which I would argue is a little bit too small. They're estimating that it will cost $20 billion over the next three decades to build that number of public chargers. My estimate is four times that. Using very back-of-the-envelope math here, we're talking about $80 billion.
