Material usage

It would be useful if we could get a report on how various materials are being used; similar to electricity and computing.
e.g. for hydrogen; 5% for cracking units, 25% for rotary kilns, 10% for silicon reactors, 60% for trucks, or some such.
Sometimes I find myself running low on a particular material and if it's heavily used material like hydrogen, coal, etc. it can be difficult to figure out where it's going.
