Heating and Cooling Seal leaks around doors, windows, and electrical sockets to prevent heated or cooled air from escaping. Keep doors and windows shut, and close fireplace vents when the fireplace is not in use to keep cooled or heated air inside the home. During heating season, wear an extra layer of clothing instead of turning up the thermostat. Keep the thermo- stat at about 68°F. For further conservation, turn the thermostat down at bedtime. Keep the thermostat at about 78°F during air-conditioning season. Use a fan to keep air circulating— this will make the area feel cooler. Water Conservation Wash clothes in warm or cold, not hot, water. Accumulate a full load before washing laundry or running the dishwasher. Fix leaky faucets, and never let water run unnecessarily. Turning off the water while brushing your teeth or shaving can save 4.5 gallons of water per minute. If you have a large-capacity toilet tank, fill plastic bottles with water, seal them, and place them in the tank. The bottles will keep the tank from filling completely, which will save up to a gallon of water per flush. Lighting and Appliances Replace traditional lightbulbs with compact fluorescent bulbs, which use less energy and last longer. Switch off lights when you leave a room. Turn off televisions, radios, computers, and other appliances when they are not in use. Use a microwave or toaster oven instead of a conventional oven when cooking a small amount of food. Don’t preheat a conventional oven for longer than necessary. Avoid opening the oven door unnecessarily while the appliance is in use.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
