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?

You could try using natural light instead of electric lighting during the day, which would help you save on electricity costs. Additionally, you could install insulation in your walls and windows to reduce the amount of heat entering or leaving your home. Finally, you could switch to LED bulbs for your lighting, as they are much more efficient than traditional incandescent bulbs.
