Utilities & Energy — one of 53 categories on the board (verticals above, functions below).
Every offering binds one capability (the provider-independent resource) to one provider, and resolves to one category of the register board — the vertical it serves or the function it performs, with the occupations whose work it carries and the records it keeps. Browsing the directory is browsing the economy graph.
