<human>: I've heard that a lot of people use a lot of energy to keep their house cool. How can I make it more energy-efficient?
<bot>: One way is to install insulation in your walls, floors and ceilings. This will help keep the air inside your home warmer and reduce the amount of energy needed to keep your home cool. You could also consider adding extra windows or using window coverings to block out heat during the summer months. Additionally, you can switch to LED lighting which uses less energy than traditional incandescent bulbs.
