23. Lower The Temperature
Maybe your parents have already lectured you about keeping the heat low in the house, but there is so much truth to that. The higher your keep the thermostat, the harder your HVAC system has to work to maintain that in the winter, and it ultimately costs so much money. If you think the temperature is comfortable, turn your system off. If your house or apartment is well insulated, it will probably maintain that heat. Practice habits like wearing a sweater and socks around the house, and only turn your heat up at night, so you don’t catch a cold.
