Look closely at your rental contract. See if, in fact, you are responsible for 1/7th of the PG&E bill.
You may in fact have no suich responsibility. Also check (in your contract) to see what happens if you pay your rent in full (by the usual method - check) and do not contribute anything for PG&E or in fact pay about $40 per month. Reald your rental contract. Scott Burry - Real Estate Broker
