One of the best ways I save on utility bills is by being mindful of my energy and water usage. I keep the thermostat at an moderate temperature and dress in layers instead of constantly adjusting the heat. I also make sure to unplug electronics when not in use and install LED light bulbs. For water conservation, I take shorter showers and only run full loads of laundry. Additionally, I thoroughly airsealed my home to prevent heated/cooled air from escaping. These simple behavioral changes and efficiency upgrades have really helped reduce my monthly utility costs.
