the thermostat setting also plays a significant role when it comes to energy usage and savings. Optimal thermostat settings
vary depending on the season and can save a family in terms of energy consumption and money. In order to appreciate these
benefits it is necessary to learn what the recommended thermostat settings are.

One of two types of thermostats may be found in most homes - manual or programmable. When a person has a manual thermostat,
he or she must set and turn on the unit manually. Once it is set, it will remain at that setting until the individual changes
it or turns it off. This type of thermostat is the most basic and is not as energy-efficient as the programmable thermostat. A
programmable thermostat is one that is programmed to automatically adjust to the best thermostat settings throughout the day.
The ideal thermostat settings for energy savings depends on the season or weather conditions.

To achieve maximum energy savings during the summer months, setting the air conditioning thermostat properly can result in a
significant reduction in one's energy bill. The optimal thermostat settings for the summer months is determined by whether
or not the house is occupied or empty. When occupied the thermostat setting should be kept at 78 degrees Fahrenheit. For every
degree warmer than 72 degrees Fahrenheit a person can expect a one to two percent savings in energy costs. In addition, ceiling
or stationary fans can also help to make the home feel cooler. When unoccupied the thermostat should be set to a warmer
temperature, such as 85 degrees. If pets are left in the home during the summer, it is important that the thermostat of an
otherwise unoccupied home is set no warmer than 80 degrees Fahrenheit.
For maximum comfort and energy savings during cold weather months, the winter thermostat setting should be kept at 68
degrees Fahrenheit while the home is occupied. As with the summer months, the winter thermostat setting should be adjusted when
there is no one home in order to enjoy the savings associated with being more energy-efficient. The ideal thermostat settings
for energy savings will be 10 to 15 degrees lower than it is when occupied. By setting the thermostat lower for a minimum of
eight hours a day, a person can save as much as 15 percent on his or her bill.
