There is a strong argument for incentivizing smart charging, which tends to be slightly more expensive to buy but has the huge opportunity to help people use electricity better at their homes or businesses—going back to some of the things Mr. Bradley said. Smart charging allows you to manage load, so that you're not charging at the times that are not good for the grid. We've actually patented Canadian patents on various smart energy technologies.
Typically, the biggest subsidies are required for the DC fast charging stations that you'd see at a highway or a rest stop; those tend to be the highest cost. Also, for multi-unit dwellings there are significant barriers, so incentives are helping to basically build out that infrastructure.
At a certain point, however, once we get higher levels of EV adoption, I don't think incentives will be required.
