How is the energy bill split in academic departments?
At the institutions where I worked in the US, a fixed overhead from grants, negotiated with the granting agency usually (e.g. X University takes YY% from all NSF grants held at X) went to those kinds of costs. I do not know of any exceptions, but we were more likely to be running refrigeration units and ovens than ion accelerators and each individual institute may have special exceptions. You would have to inquire directly.
