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?

One way to make your home more energy-efficient is to insulate the walls, floors and roofs of your house. This will help reduce the amount of heat that enters or leaves the building. You can also install double-glazed windows, which are much more energy efficient than single-paned windows. Additionally, you could look into installing solar panels on your roof to generate electricity and lower your energy costs.
