Maybe its something more basic, Disney did announce going Carbon free by whenever, maybe its something along those lines. replacing electric grids, adding solar power, wind power, etc, etc.
I never understood why Disney did just cover the undeveloped areas of the southern part of the property with solar panels and wind farms, sure the capital investment might be high but you would end up with a sustainable power supply and wouldn't have to deal with the pricing of electricity.
If they then had enough capacity they theoretically could also start cracking their own hydrogen and run all the buses off of that too so the ever changing price of fuel doesn't need to be budgeted or figured out.
Thats just my 2 cents though, but its what I would do.
