Yes. With regard to transportation, I indicated that we should focus on public fleets, largely because public fleets scale faster than individual light-duty cars and they scale faster than private heavy-duty fleets.
For example, in transit, buses are not purchased one by one. They are purchased in units of 10, then 50 then 100. They're mass fleet procurements that allow for a stepwise function of growth.
In the heavy-duty sector, electrification and hydrogen electrification of transit buses are the gateway to coaches and trucks because they fuel at the same pressure levels and they use the same high-powered charging systems that are not transferable to the car light-duty sector.
There is a component here where if we want to get bang for our buck, the focus should always be on the heavy-duty fleet sector—public first, followed by the private freight sector. They get greater bang for their buck and greater greenhouse gas emissions reduction, and they buy en masse. They do not buy them one by one.
In comparison, with electric cars, which I'm a big believer in, you still have to convince households to make an individual economic choice. That is a much slower logarithmic growth compared to what you get in the stepwise function of fleet adoption on the heavy-duty side.
