Utilities with three separate tenants and one electrical panel/meter

[Autumn Brooke]

I have a three bedroom, single family home. I am currently renting one bedroom to a tenant. I am moving out of the house in June and intend to rent the other two bedrooms to two additional tenants, unrelated to the first tenant. Three separate leases.

I have one electric panel (single family home). What is the best way to handle electricity? 

Keep it in my name and divide the electrical cost by three each month and have them pay me? 

Put the electricity in one of the tenants' names and have them be responsible for collecting from other two tenants?

THANK YOU so much in advance! New tenant living situation for me!
