TIP 2: Turn off the water heater. It's not like you'll be using it! You can choose to either completely shut it off, or if there's a vacation setting, feel free to use it.
TIP 3: Get rid of your energy vampires. It's not Halloween yet, but there are still vampires lurking around in the shadows of your house. Your electronics! Again, you're not going to use them, so keeping them plugged in is just a waste.
TIP 4: Keep water around. Bottle up some gallons of water and place them around the house for when it gets too dry.
TIP 5: Cover up those windows. Your windows are a major source of heat gain in your house, so just by covering them up, you'll be saving a ton of energy. A window shade screen works best, but any kind of shading will do.
Safe travels, everyone!
