<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, roof and attic to reduce the amount of heat that escapes through your home’s exterior surfaces. You can also switch to energy-efficient light bulbs or appliances, and consider installing a programmable thermostat to control your home's temperature. Finally, you can look into solar panels to generate electricity for your home.
