Electric and gas expense are part of my rent. How do I get my own accounts and meters so I can track my own expenses?

I don't understand your question.

If you are in an apartment complex, then you should already have your own service and the apartment complex should have a separate meter for all common areas.

If you are renting a duplex unit, the same as above is true.

However, if you are renting part of a home that has been renovated to have an apartment, then it is a bit dicey because there can be only one meter for a residence.

The cost of reworking the electrical system may far outweigh the existing set-up, unless the area you are renting is a stand-alone unit as in a "Mother-In-Law" home.

I would talk to the landlord and the utility company.

That is something you discuss with the landlord, and utility company.

If the gas and electric are part of your rent and is a set fee there is not much you can do.

If the rent fluctuates from month to month then you should discuss this with your landlord to get a copy of bill with your rent tab.

First there may or may not be separate meters. One of my duplex houses just has one meter and I charge a certain rent that covers electric, water, trash and so on.

So first you need to talk to the landlord and see if there are separate meters to start with. Then you discuss a new rental agreement where you pay the electric and gas yourself. Then you call up the provider and change it to your name, normally paying deposit and sometimes a hook up cost.

Years ago, I have added a second meter to show power consumed by 1/2 of a Duplex.
You read the Main Meter, Subtract the reading of the second Meter, you can determine who used how much.

Sitesage has Inductive coils you place around each wire at the breakers, You can easily monitor How much Electricity is used Remotely with Their App. Also displays a Graph showing how much each individual circuit is used and at what time.

Bottom line here is you need to talk to the landlord and the utility. You have to get permission from the landlord and pay the utility for the installation.
