Energy.gov is the official website of the United States Department of Energy. On this website, you can find resources on how to conserve energy. Read the information about thermostats then consider the following question: On a hot summer day, you need to leave your house for 30 minutes. To use the least amount of energy, should you turn off your air conditioning system, turn up the thermostat, or leave it set at your normal temperature? For those of you more familiar with cold winter days, you may consider the same about your heating system on a cold winter day: Should you turn it off, turn the thermostat down, or leave it set at your normal temperature? Explain your answer.

When it comes to conserving energy in a residential setting, understanding how thermostats influence energy consumption during short absences is vital. For hot summer days, the most energy-efficient strategy is to set the thermostat to a higher temperature, effectively turning off the air conditioning or turning it up significantly. This prevents the air conditioner from running unnecessarily while the house is unoccupied, thus conserving energy. Conversely, in winter, lowering the thermostat or turning off the heating system during a short absence also reduces energy use because heating systems consume a significant amount of energy when maintaining indoor temperatures.

Research from the Department of Energy recommends setting thermostats to higher temperatures in summer when away (around 78°F or 26°C) and lowering thermostats in winter (to about 68°F or 20°C) to save energy without compromising comfort upon return (U.S. Department of Energy, 2023). These practices minimize the workload on the HVAC system, resulting in substantial energy savings. It is inefficient to leave the thermostat at a normal temperature during short periods because the system will continue to operate unnecessarily, wasting energy. Moreover, modern programmable thermostats can automate this process to optimize energy conservation based on occupancy patterns.

Therefore, the optimal approach is to adjust the thermostat to a more energy-conserving setting during short absences, rather than turning off the system entirely or leaving it at regular levels. This balance ensures energy savings and comfort while preventing excessive energy use when the house is unoccupied. Such strategies uphold the principles of energy efficiency promoted by the Department of Energy and contribute significantly to reducing overall energy consumption and greenhouse gas emissions (Energy.gov, 2023).

In conclusion, whether in summer or winter, adjusting the thermostat to an energy-saving setting during short periods of absence is the most effective way to conserve energy. This approach reduces unnecessary operation of HVAC systems while maintaining comfort upon return, aligning with energy conservation guidelines provided by the U.S. Department of Energy.
