Why so much money ? We pay every month close to $1...

Why so much money ? We pay every month close to $1000 for a house of 2 hard working people, we have no internet, no children, we unplug everything , our water heater is set to 120, we cook 2 times a week, all lights are off in all rooms unless we are in the room which is the master bedroom. What is going on? I can't take it anymore . I lived in jersey city in New York, in Florida, I never paid so much money before, I had ch I'll Loren before living with me , I used to pay the most in winter and summer is $200 .
HELP!!!!!!!!!!!!!!!!!!!!!!
