Add a fuel consumption tab to the production pane.

[JasonC]

I'd like to see a summary of all resources consumed as fuel (wood, coal, solid fuel).

I think it should be a separate tab in the production pane, because the rates/minute would be too low to see when scaled on the current consumption graph.

Also somewhat related (as far as things not shown on the production window): See raw material mining rates (which I didn't really post as a suggestion, it was just a question, but mining production rates might also fit nicely on the same tab as fuel consumption rates since there's room for two graphs).
