Ameren Illinois, a leading energy company, is offering valuable tips to help you save on your electricity bill this summer. Turn off the lights: According to Ameren Illinois spokesman Brian Bretsch, a simple habit such as turning off lights in unoccupied rooms can make a significant impact on your energy bill. Make sure to also change the air conditioner filter regularly to ensure optimal performance. Additionally, be mindful of your gaming habits as paused games and other electronics left on standby still consume electricity. By implementing these energy-saving practices, you can enjoy a comfortable summer while also reducing your energy costs.
