Turn up the thermostat
Setting your thermostat to 85 degrees will prevent your air conditioning system from working overtime to cool your home while you’re not there.
Turn down the water heater
Similarly, turning your water heater down to the lowest setting will ensure that you are not using energy to heat water when you don’t need it.
Turn off the lights
Turn off all unnecessary lights, and consider using a timer if you want to use a light for security at night.
Turn off AND unplug electronics
Electronic devices like computers, TVs and microwaves use energy even when they are turned off. Use a power strip so that you can fully shut down all of your unused devices with a single flip of a switch.
Turn to technology
Technology can be a huge help when it comes to saving energy while you’re not at home. Smart and programmable thermostats can be set to automatically adjust the temperature
setting when you are away from home. In addition, smart thermostats are Internet-connected and allow you to remotely control the temperature in your home from your phone, computer or tablet.
