Yeah, so most, you know, if you're a university, the ones that are taking advantage of these utility scale projects, you're doing these power purchase agreements, right. In some cases, it's for to like direct delivery. But in most cases, it's virtual, where the facility could be built in Texas, and there's this thing called additionality, which is without my money that wouldn't have been built. So with my commitment for 10 years, let's say, for a purchase, that allows the wind developer to turn around and say to the bank, hey, I have university X now committed to buy this from me for the next 10 years. Now I can turn around and get the financing for that. On site, you know, in the campus, most campuses are land constrained; they can put solar on a bunch of rooftops, carports, which will be a huge new--carports are going to be one of the next areas after rooftops to get built out. It's already happening. Phoenix, for example, the city's doing all kinds of carports stuff. But yeah, for campuses, you do everything you can on site. First, make yourself efficient, then add the renewables, sometimes the batteries, and then if you need to continue to decarbonize, it usually involves some kind of a contractual structure with an external party developing utility scale stuff, which is cheaper than what you're doing on site anyway, because of the scale.
