According to the U.S. Department of Energy, more than 40 percent of residential energy is used to cool and heat homes. New Jersey Energy Choice, developed by the N.J. Board of Public Utilities, Trenton, offers the following conservation tips to consumers to save energy and money:
• Keep windows closed during the day, and draw blinds and draperies to keep the sun out.
• If planning to stay in one room for an extended period of time, use a small fan or ceiling fan instead of central air conditioning.
• Run large appliances (dishwashers, washing machines or dryers) during off-peak hours such as early morning or late evening, when it is cooler and there is less demand for energy.
• Line-dry clothes outside instead of using a dryer.
• When cooking, try to avoid using the oven or stove. Consider preparing meals such as salads and sandwiches or use an outdoor grill.
• Set refrigerator temperatures between 37-40 degrees Fahrenheit. Be sure the refrigerator is stocked as more energy is used to cool an empty refrigerator than a full one.
• When using air conditioning, make sure other appliances are not on unnecessarily, as many appliances create added heat and moisture, causing air conditioning to work harder.
• Clean or replace filters on central air conditioners monthly and have air conditioners serviced by a professional each year.
• Set the central air conditioner thermostat at 78 degrees or higher, as each degree above 78 degrees can decrease energy usage and expense for cooling 3 to 5 percent.
• Consider planting trees or shrubs to shade the central air unit, but do not block the airflow. An air conditioner operating in the shade uses 10 percent less electricity than one working in the sun.
