Yesterday (Oct. 4) marked Energy Efficiency Day, and NIPSCO is reminding customers that small changes around the house can have big energy savings during the colder months ahead.

• Use natural light: Natural light is a source of free heat that many homes overlook. Leave your
curtains open during the day to allow your rooms to absorb some warmth. Furthermore, natural
light has physiological benefits – it improves your vision, helps you sleep, and can improve your

• Turn back the thermostat: First and foremost, be cautious of how high you set the thermostat
temperature during the winter. Your energy bills will rise as you use more heat, especially if it is
competing with colder outdoor temperatures. You’ll also make your heating, ventilation and air
conditioning (HVAC) system work harder, perhaps shortening its lifespan. Turn down the
thermostat a few degrees if you’re looking for strategies to save energy.

• Save on hot water – Don’t set your water heater temperature higher than 120 degrees. This will
help save energy and avoid scalding.

• Seal cracks and leaks: According to the U.S. Department of Energy, fixing leaks around the
house can reduce energy expenses by five to 30 percent. Spending a day caulking, or
weatherstripping your windows and doors will help seal air leaks, which may be significant
energy drains.

• Maintain your furnace – Schedule your annual furnace tune-up, ideally before the first cold
weather arrives. A licensed HVAC technician can make sure your furnace is clean and safe before
its season long workout.

• Buy ENERGY STAR products – Look for ENERGY STAR labels when purchasing new electronics.
These products have been certified as high-efficiency and low-energy, consuming up to 65 percent
less energy than non-certified alternatives.

Beyond these helpful tips, NIPSCO offers a range of programs designed to help customers save energy
and money, including rebates, home energy assessments, an online marketplace and more.
