High electric bill for no reason

Florida power and light told me that RV tenants who us fans, tv, Central air, washer and dryer and use of appliances use about 525 kwh on a average per month.  To calculate your monthly average electricity bill in Florida is to multiply the kwh say 525 kwh used per month times 14 cents per kwh .   525x 0.014= $ 7.35  per month.  That is the amount of electricity you should pay for.  And if the park charges an additional  $7.50 for a monthly base charge.  You should only be paying the $7.35 ( electric  charge) + $7.50 (base charge) = 14.85 per month for electric use for one month in 5th wheel.  Less usage less money.  Anything over that is a red flag.
