OG&E offers this tip to keep homes cool and comfortable and lower energy costs:

 Use a programmable thermostat to manage your home’s temperature. Set your thermostat at the highest comfortable temperature when you’re home and raise it a few degrees when you’re not home. Each degree a thermostat is raised can save up to three to four percent on the cost of operating an air conditioner. Customers on OG&E’s SmartHours® program receive a free programmable thermostat and incentives for shifting their energy outside of the company’s peak hours—nearly half-price electricity during non-peak times.
