Kyle Sandilands reveals his outrageous electricity bill after leaving the air-conditioning on in his $13.8m mansion when no one's at home. This is over 25 times the average household energy bill in New South Wales, which according to the Australian Energy Market Commision (AMEC) is $1,253 a year. 'I don't worry about electricity bills,' Kyle said to his co-host Jackie O Henderson on their KIIS FM show on Friday.
